Build Interactive Gantt Charts with Airtable, Gatsby & React — SitePoint

It’s a typical state of affairs: you want to develop an app that connects to data from a spreadsheet software program or one other data provide. On this text, I’ll current you learn to implement an software program of this type with the Gatsby framework. In our occasion software program, duties shall be imported from an Airtable workspace and visualized as a Gantt chart. The buyer can switch the duties by drag and drop, after which all changes shall be synchronized with Airtable. You must make the most of the problem as a template for each form of scheduling apps.

You can try the consequence keep on my Gatsby Cloud web site. The src data of the problem will probably be current in my GitHub repository.

Key Takeaways

• Gatsby simplifies the blending of assorted data sources like Airtable into features, enabling the creation of interactive Gantt charts for job administration.
• React is employed to develop the doorway end of the Gantt chart, which allows duties to be manipulated straight by the use of drag-and-drop and synchronizes changes with Airtable.
• The problem setup contains using Node.js, npm, and the Gatsby CLI to create a static web site that tons of shortly ensuing from pre-built HTML data served from the server.
• Airtable serves as a result of the backend, storing duties and property which can be fetched using GraphQL queries facilitated by the Gatsby provide plugin for Airtable.
• Precise-time synchronization between the Gantt chart and Airtable is achieved using every server-side (webhooks for automated rebuilds) and client-side (polling with React’s useEffect) updates.
• Enhancements like making duties draggable contained in the Gantt chart are managed through React components, with changes pushed once more to Airtable using its REST API to verify data consistency all through platforms.

Setting Up the Problem

Gatsby is a static web site generator. This suggests you write your software program with React, and Gatsby interprets your code into HTML data that are understandable to the browser. This assemble course of is carried out at frequent intervals on the server side, in distinction to straightforward web features the place the HTML code is first assembled on the buyer side throughout the client’s browser. The HTML data are on account of this truth statically accessible on the server (due to this fact the establish static web site generator) and will probably be despatched on to the buyer when requested. This reduces the loading time of the equipment for the buyer.

SitePoint’s Gatsby tutorial offers all the info it’s advisable to develop an software program with this framework. When you want to develop my occasion software program step-by-step, that you must start as outlines beneath.

First, that you must get hold of and arrange Node.js. You can check if it’s put in appropriately by typing node -v on the console. The current mannequin of Node must be displayed:

node -v
> v14.16.0

With Node we moreover get npm, the Node package deal deal supervisor. With this instrument, we’ll now arrange the Gatsby CLI:

npm arrange -g gatsby-cli

We’re capable of create a model new problem using the Gatsby CLI. I establish it “gantt-chart-gatsby”:

gatsby new gantt-chart-gatsby

Then switch into the problem folder with the command cd gantt-chart-gatsby and assemble the problem with the command gatsby develop. Now you can open the index internet web page of the problem throughout the browser on http://localhost:8000. At first, that you must solely see the welcome internet web page that Gatsby has prepared for us.

Throughout the subsequent step, that you must research the src folder of the problem. The subfolder src/pages incorporates the React components of the particular person pages of the problem. For now, it’s sufficient so as to preserve the index.js file for the index internet web page, on account of, in our occasion software program, we solely need one internet web page. You can delete the other data on this folder, other than 404.js (which will probably be useful if any individual enters a fallacious deal with).

It’s an outstanding place to start should you occur to overwrite the current code in index.js with this code:

import * as React from 'react'

const IndexPage = () => {
  return (
   most necessary>
      title>Gantt Chart/title>
      h1>Welcome to my Gatsby Gantt Chart/h1> 

    /most necessary>
  )
}

export default IndexPage;

You can assemble the problem as soon as extra with the command gatsby develop on the command line and open the index internet web page throughout the browser. Now that you must see an empty internet web page with the heading “Welcome to my Gatsby Gantt Chart”.

Establishing the Entrance End with React

The first mannequin of the index internet web page

We’re going to implement the Gantt chart as a reusable React aspect. Sooner than I make clear the implementation of the aspect intimately throughout the following sections, I’d first like to point the best way it’s initialized and embedded throughout the index internet web page. So I’d counsel you to hold off using the gatsby develop command until we’ve accomplished the first mannequin of the aspect. (I’ll allow you to perceive as soon as we’re ready!)

On this occasion problem, I benefit from the thought of “jobs” and “property”. Jobs are the duties that are drawn into the chart cells and that could be moved by drag and drop. Sources embody the labels for the rows whereby the roles will probably be moved. These will probably be names for the duties, nonetheless in numerous use cases moreover the names of people, autos or machines ending up the duties.

Jobs and property are handed to the Gantt chart aspect as properties. Sooner than connecting the obligation administration instrument to Airtable, we fill the lists with some hard-coded check out data in JSON format:

import * as React from "react";
import {GanttChart} from "../GanttChart";
import "../varieties/index.css";

let j = [
  {id: "j1", start: new Date("2021/6/1"), end: new Date("2021/6/4"), resource: "r1"},
  {id: "j2", start: new Date("2021/6/4"), end: new Date("2021/6/13"), resource: "r2"},
  {id: "j3", start: new Date("2021/6/13"), end: new Date("2021/6/21"), resource: "r3"},
];

let r = [{id:"r1", name: "Task 1"}, {id:"r2", name: "Task 2"}, {id:"r3", name: "Task 3"}, {id:"r4", name: "Task 4"}];

const IndexPage = () => {
  return (
    most necessary>
      title>Gantt Chart/title>
      h1>Welcome to my Gatsby Gantt Chart/h1> 
      GanttChart jobs={j} property={r}/>
    /most necessary>
  )
};

export default IndexPage;

CSS varieties for the Gantt chart

Throughout the subsequent step, we create a model new index.css file throughout the varieties folder. (If the folder doesn’t exist, create a model new folder varieties throughout the folder src of the problem.) The following CSS settings administration the format and look of the Gantt chart:

physique{
  font-family: Arial, Helvetica, sans-serif;
}

#gantt-container{
  present: grid;     
}

.gantt-row-resource{
  background-color:whitesmoke;
  coloration:rgba(0, 0, 0, 0.726);
  border:1px robust rgb(133, 129, 129);
  text-align: coronary heart;
  padding: 15px;
}

.gantt-row-period{
  background-color:whitesmoke;
  coloration:rgba(0, 0, 0, 0.726);
  border:1px robust rgb(133, 129, 129);
  text-align: coronary heart;

  present:grid;
  grid-auto-flow: column;
  grid-auto-columns: minmax(40px, 1fr);
}

.interval{
  padding: 10px 0 10px 0;
}

.gantt-row-item{
  border: 1px robust rgb(214, 214, 214);
  padding: 10px 0 10px 0;
  place: relative;
  background-color:white;
}

.job{
  place: absolute;
  peak:38px;
  prime:5px;
  z-index: 100;
  background-color:rgb(167, 171, 245);
  cursor: pointer;
}

Implementing the GanttChart aspect

Now I’ll make clear the implementation of the GanttChart aspect in extra aspect. First, we wish a file named GanttChart.js throughout the src folder. On this tutorial, I benefit from a simplified mannequin of the GanttChart for only one month (June 2021). An extended mannequin with select fields for starting month and end month will probably be found at GitHub beneath the establish GanttChart_extended.js.

The chart desk is constructed up in three steps, represented by the capabilities initFirstRow, initSecondRow and initGanttRows
:

import React from 'react';

export class GanttChart extends React.Half {

    names = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];

    constructor(props) {

        large(props);       

        this.state = {
            dateFrom: new Date(2021,5,1),
            dateTo: new Date(2021,5,30),
        };
    }

    render(){

        let month = new Date(this.state.dateFrom.getFullYear(), this.state.dateFrom.getMonth(), 1);

        let grid_style = "100px 1fr";

        let firstRow = this.initFirstRow(month);
        let secondRow = this.initSecondRow(month);
        let ganttRows = this.initGanttRows(month);

        return (

            div className="gantt-chart">
                div id="gantt-container" mannequin={{gridTemplateColumns : grid_style}}>
                    {firstRow}
                    {secondRow}
                    {ganttRows}
                /div>
            /div>
        );
     }


    initFirstRow(month){...}

    initSecondRow(month){...}

    initGanttRows(month){...}


    

    formatDate(d){ 
        return d.getFullYear()+"-"+this.zeroPad(d.getMonth()+1)+"-"+this.zeroPad(d.getDate());  
    }

    zeroPad(n){
        return n10 ? "0"+n : n;
    }

    monthDiff(d1, d2) {
        let months;
        months = (d2.getFullYear() - d1.getFullYear()) * 12;
        months -= d1.getMonth();
        months += d2.getMonth();
        return months  0 ? 0 : months;
    }

    dayDiff(d1, d2){   
        let diffTime = Math.abs(d2 - d1);
        let diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24)); 
        return diffDays;
    }

}

Throughout the initFirstRow function, the first row of the chart desk is generated. As you can see from the picture above, the first row consists of two grid cells. These are generated as divs, which in flip are inserted as children into the “gantt-container” (see the itemizing above). The second div moreover incorporates the label for the current month.

React requires a singular “key” property for all components that are part of an enumeration. This helps to optimize the rendering effectivity:

 initFirstRow(month){

    let components = []; let i = 0;

    components.push(div key={"fr"+(i++)} className="gantt-row-resource">/div>);

    components.push(div key={"fr"+(i++)} className="gantt-row-period">div className="interval">{this.names[month.getMonth()] + " " + month.getFullYear()}/div>/div>);

    return components;
 }

The next row of the chart desk is generated throughout the initSecondRow function. We use the equivalent principle as soon as extra: for each desk cell, a div is created. It is advisable make sure that the divs are nested appropriately (the second div throughout the row incorporates specific particular person divs for day by day of the month) so that the CSS Grid settings (see the index.css file) will produce the required format:

initSecondRow(month){

    let components = []; let i=0;

    
    components.push(div key={"sr"+(i++)} mannequin={{borderTop : 'none'}} className="gantt-row-resource">/div>);

    let days = [];

    let f_om = new Date(month); 
    let l_om = new Date(month.getFullYear(), month.getMonth()+1, 0); 

    let date = new Date(f_om);

    for(date; date  l_om; date.setDate(date.getDate()+1)){

        days.push(div key={"sr"+(i++)} mannequin={{borderTop: 'none'}} className="gantt-row-period interval">{date.getDate()}/div>);
    }

    
    components.push(div key={"sr"+(i++)} mannequin={{border: 'none'}} className="gantt-row-period">{days}/div>);

    return components;

}

The remaining rows of the chart desk are generated throughout the initGanttRows function. They embody the grid cells into which the roles are drawn. As soon as extra, the rendering is completed row by row: for each row we first place the establish of the helpful useful resource, then we iterate over the particular person days of the month. Each grid cell is initialized as a ChartCell aspect for a particular day and helpful useful resource. With the cell_jobs guidelines, the particular person cell is assigned the roles that should be drawn into it (normally that’s exactly one job):

initGanttRows(month){

    let components = []; let i=0;

    this.props.property.forEach(helpful useful resource => {

        components.push(div key={"gr"+(i++)} mannequin={{borderTop : 'none'}} className="gantt-row-resource">{helpful useful resource.establish}/div>);

        let cells = [];

        let f_om = new Date(month);
        let l_om = new Date(month.getFullYear(), month.getMonth()+1, 0);

        let date = new Date(f_om);

        for(date; date  l_om; date.setDate(date.getDate()+1)){

            let cell_jobs = this.props.jobs.filter((job) => job.helpful useful resource == helpful useful resource.id && job.start.getTime() == date.getTime());

            cells.push(ChartCell key={"gr"+(i++)} helpful useful resource={helpful useful resource} date={new Date(date)} jobs={cell_jobs}/>);
        }

        components.push(div key={"gr"+(i++)} mannequin={{border: 'none'}} className="gantt-row-period">{cells}/div>);

    });

    return components;
}

Now add the following code for the ChartCell aspect on the end of GanttChart.js. The aspect renders a single desk cell of the chart as a div containing quite a lot of jobs as child components. The HTML code for displaying a job is obtainable by the getJobElement function:

class ChartCell extends React.Half {

    constructor(props) {

      large(props);

      this.state = {
        jobs: props.jobs
      }
    }

    render(){

      let jobElements = this.props.jobs.map((job) => this.getJobElement(job));

      return (
        div 
            mannequin={ this.props.date.getDay()==6) ? "whitesmoke" : "white" } 
            className="gantt-row-item">
            {jobElements}
        /div>
      );
    }

    getJobElement(job){

        let d = this.dayDiff(job.start, job.end);

        
        return (
        div    mannequin={{width: "calc("+(d*100)+"% + "+ d + "px)"}} 
                className="job" 
                id={job.id} 
                key={job.id}
        >

        /div>
        );
    }

    dayDiff(d1, d2){   
        let diffTime = Math.abs(d2 - d1);
        let diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24)); 
        return diffDays;
    }
}

At this degree, you can assemble the problem from the inspiration folder using the gatsby develop command. The hard-coded jobs from the index internet web page must be seen throughout the Gantt chart. They will’t be dragged and dropped however, nonetheless we’ll preserve that later.

Integrating Info from Airtable

It’s time to connect our software program to Airtable so we’ll import jobs and property from there. First, create a free account at Airtable. After logging in, you’ll see an “Untitled Base” (see image beneath). Click on on Add a base, then Start from scratch, and enter a repute to your base. I entered “Course of Supervisor”.

Organising the Airtable base with the “Jobs” and “Sources” tables

Now you can define the tables to your base, throughout the following steps:

1. Define the desk “Jobs” with the fields id (space type: textual content material), start (space type: Date) and end (space type: Date).
2. Define the desk “Sources” with the fields id (space type: textual content material) and establish (space type: textual content material).
3. Go to the desk “Jobs”, add a space helpful useful resource with the sector type “Hyperlink to a special doc”, then choose the sector id as a lookup space for the desk “Helpful useful resource”.

After these steps, your tables must look like throughout the footage beneath.

Importing data from Airtable with GraphQL and Gatsby’s Airtable plugin

Subsequent, we want to import data from Airtable into our software program. For this goal, arrange the plugin “gatsby-source-airtable” with npm arrange --save gatsby-source-airtable. Then, modify the gatsby-config.js file in your problem folder as confirmed throughout the guidelines beneath:

module.exports = {
  siteMetadata: {
    siteUrl: "https://www.yourdomain.tld",
    title: "Gatsby Gantt Chart",
  },
  plugins: [

  "gatsby-plugin-gatsby-cloud",

  {
    resolve: "gatsby-source-airtable",
    options: {
      apiKey: "XXX", 
      concurrency: 5, 
      tables: [
        {
          baseId: "YYY",
          tableName: "Jobs",    
        },
        {
          baseId: "YYY",
          tableName: "Resources",
        }
      ]
    }
  }
  ],
};

Now we’ll try and fetch data from Airtable. Start your software program with gatsby develop, then open the GraphiQL editor throughout the browser at http://localhost:8000/___graphql and paste the following query into the world on the left:

{
  jobs: allAirtable(filter: {desk: {eq: "Jobs"}, data: {}}) {
    edges {
      node {
        data {
          id
          start
          end
          id__from_resource_
          helpful useful resource
        }
        recordId
      }
    }
  }
  property: allAirtable(
    filter: {desk: {eq: "Sources"}}
    sort: {fields: [data___name], order: ASC}
  ) {
    edges {
      node {
        data {
          id
          establish
        }
      }
    }
  }
}

Click on on on the arrow picture to run the query. The outcomes of the query ought to look on the exact side.

Now it’s time to remove the hardcoded lists with jobs and property in index.js. Substitute the code in index.js as confirmed throughout the following itemizing. What’s occurring proper right here? First, on the end of the file you can see a so-called “internet web page query” that requests all jobs and property. The outcomes of the query is mechanically assigned to the data property of the aspect IndexPage. Thus, the data property retailers exactly what you’ve seen as a query consequence throughout the GraphiQL editor on the exact side. We’ll use the map function to transform the jobs and property arrays into our most popular format.

Even when it seems a bit cumbersome, we have to keep up the properties recordID and id__from_resource, which can be mechanically created by Airtable, for all jobs. That’s wanted so as that we’ll later save changes to the roles by the use of the Airtable REST API:

import * as React from "react"
import { useStaticQuery, graphql } from "gatsby"
import {GanttChart} from "../GanttChart"
import '../varieties/index.css';


const IndexPage = (data) => {

  let j = data.data.jobs.edges.map(edge => {

    let s = new Date(edge.node.data.start);
    s.setHours(0);

    let e = new Date(edge.node.data.end);
    e.setHours(0);

    return {
      airtable_id: edge.node.recordId,
      id:edge.node.data.id,
      start: s,
      end: e,
      helpful useful resource: edge.node.data.id__from_resource_[0],
      resource_airtable_id: edge.node.data.helpful useful resource[0]
    };
  });

  let r = data.data.property.edges.map(edge => {

    return{
      id: edge.node.data.id,
      establish: edge.node.data.establish
    }
  });

  if(r && j){
    return (
      most necessary>
        title>Gantt Chart/title>
        h1>Welcome to my Gatsby Gantt Chart/h1> 
        GanttChart jobs={j} property={r}/> 
      /most necessary>
    )
  }else{
    return (
      most necessary>
        title>Gantt Chart/title>
        h1>Welcome to my Gatsby Gantt Chart/h1> 
        p>Missing data.../p> 
      /most necessary>
    )
  }
}

export const query = graphql`
      query{
        jobs: allAirtable(filter: {desk: {eq: "Jobs"}, data: {}}) {
          edges {
            node {
              data {
                id
                start
                end
                id__from_resource_
                helpful useful resource
              }
              recordId
            }
          }
        }
        property: allAirtable(
          filter: {desk: {eq: "Sources"}}
          sort: {fields: [data___name], order: ASC}
        ) {
          edges {
            node {
              data {
                id
                establish
              }
            }
          }
        }
      }
  `
export default IndexPage;

If you assemble and start your software program domestically with gatsby develop
, the data is fetched from Airtable and displayed in your Gantt chart. If you’ve prepare a Gatsby Cloud web site in step with the Gatsby tutorial, the placement is updated as shortly as you push the code changes to the associated GitHub account. Nonetheless, you’ll uncover that the Airtable query is just executed when the problem is constructed (irrespective of whether or not or not that happens domestically or on the Gatsby Cloud web site). If you modify the data in your Airtable base, the changes aren’t mirrored throughout the Gantt chart besides you re-build the problem. That’s typical for the server-side rendering technique of Gatsby.

Throughout the subsequent half, we’ll concentrate on learn to address changes throughout the data.

Realizing a Two-way Synchronization between Gatsby and Airtable

In our occasion, changes to the data will probably be made in Airtable (by modifying the desk cells) or throughout the Gantt chart (by drag and drop). For synchronizing these elements, I observe a hybrid approach that features every server-side and client-side substitute operations.

1. Change changes from Airtable to the Gantt chart (server-side)

Gatsby gives webhooks to remotely set off the server-side assemble course of. It’s doable to configure Airtable to mechanically set off the assemble hook on certain events (akin to creating or altering data), supplied you’ll have knowledgeable membership there. (You’ll uncover further detailed particulars in regards to the settings that are wanted for this goal proper right here).

2. Change changes from Airtable to the Gantt chart (client-side)

Whereas the equipment is used throughout the browser, the Gantt chart must load updates from Airtable dynamically (for example, at a certain time interval). To make the tactic straightforward, we merely want to re-download the entire lists of jobs and property on the required interval. For this, we’ll use the official Airtable API.

Throughout the IndexPage aspect, we use React’s useState hook to set the lists with the roles and property as a result of the aspect’s state. Then we apply the useEffect hook to set an interval at which the function loadDataFromAirtable must be referred to as as quickly because the aspect has been initialized:

const IndexPage = (data) => {

  let j = data.data.jobs.edges.map(edge => {...});
  let r = data.data.property.edges.map(edge => {...});

  const [resources, setResources] = useState(r);
  const [jobs, setJobs] = useState(j);

  useEffect(() => {
    const interval = setInterval(() => { 

      let jobsLoaded = (j) => { setJobs(j) };
      let resourcesLoaded = (r) => { setResources(r) };

      loadDataFromAirtable(jobsLoaded, resourcesLoaded);

    }, 60000);  

    return () => clearInterval(interval);
  }, []);

  if(property && jobs){
    return (
      most necessary>
        title>Gantt Chart/title>
        h1>Welcome to my Gatsby Gantt Chart/h1> 
        GanttChart jobs={jobs} property={property}/> 
      /most necessary>
    )
  }else{
    return (
      most necessary>
        title>Gantt Chart/title>
        h1>Welcome to my Gatsby Gantt Chart/h1> 
        p>Missing data.../p> 
      /most necessary>
    )
  }
}

For the implementation of the loadDataFromAirtable function, we try the documentation of the Airtable API. The documentation is tailor-made to the chosen base (in our case “Course of Supervisor”). If you click on on on Jobs Desk and Itemizing data on the left side, you’ll see the exact development of a GET request to retrieve the data of all jobs throughout the “curl” house. This request will probably be utilized very merely in JavaScript using the “fetch” approach.

So, to acquire the data of all jobs and property, we execute two asynchronous GET requests to Airtable in sequence. I’ve masked the exact URLs on account of they embody my personal API key:

As a check out, you could make some changes to the job data in your Airtable base. After the given interval time (proper right here one minute) the Gantt chart ought to switch mechanically in your browser.

3. Change changes from the Gantt chart to the Airtable base (client-side)

Sooner than the buyer can modify the Gantt chart, we must always first make the roles draggable. For this, substitute the ChartCell aspect as follows:

class ChartCell extends React.Half {

    constructor(props) {

      large(props);
    }

    render(){

      let jobElements = this.props.jobs.map((job) => this.getJobElement(job));

      let dragOver = (ev) => {ev.preventDefault()};

      let drop = (ev) => {

        ev.preventDefault(); 

        let job_id = ev.dataTransfer.getData("job");  

        this.props.onDropJob(job_id, this.props.helpful useful resource.id, this.props.date)

      };

      return (
        div 
            mannequin={ this.props.date.getDay()==6) ? "whitesmoke" : "white" } 
            className="gantt-row-item" onDragOver={dragOver} onDrop={drop}>
            {jobElements}
        /div>
      );
    }

    getJobElement(job){

        let d = this.dayDiff(job.start, job.end);

        return (
        div    mannequin={{width: "calc("+(d*100)+"% + "+ d + "px)"}} 
                className="job" 
                id={job.id} 
                key={job.id}
                draggable="true"
                onDragStart={this.dragStart}>
        /div>
        );
    }

    dragStart(ev){ ev.dataTransfer.setData("job", ev.objective.id);}

    dayDiff(d1, d2){

        let diffTime = Math.abs(d2 - d1);
        let diffDays = Math.ceil(diffTime / (1000 * 60 * 60 * 24)); 
        return diffDays;
    }
}

Implementing drag and drop isn’t notably troublesome with JavaScript. It is advisable implement handlers for the events onDragStart (for the draggable components), onDragOver and onDrop (for the drop targets), as confirmed in this tutorial.

We’ve got to specify which handler function is called on the onDropJob event, which is triggered by the drop handler. Throughout the initGanttRows function, substitute the following line:

cells.push(ChartCell key={"gr"+(i++)} helpful useful resource={helpful useful resource} date={new Date(date)} jobs={cell_jobs} onDropJob={this.dropJob}/>);

Throughout the GanttChart aspect, add the function dropJob:

dropJob(id, newResource, newDate){

      let job = this.props.jobs.uncover(j => j.id == id );

      let newJob = {};
      newJob.helpful useful resource = newResource;

      let d = this.dayDiff(job.start, job.end); 
      let end = new Date(newDate);
      end.setDate(newDate.getDate()+d);

      newJob.start = newDate;
      newJob.end = end;

      this.props.onUpdateJob(id, newJob);
  };

The exact modification of the job guidelines is completed throughout the mom or father IndexPage aspect in index.js. The slice approach is used to create a reproduction of the job guidelines. The job that was moved using drag and drop is positioned throughout the guidelines based on its ID and is given the model new properties. After that, the state of the IndexPage aspect is updated by calling setJobs. Please observe that, exactly now, a re-render of the Gantt chart aspect is triggered and now the job ingredient appears at its new place:

const IndexPage = (data) => {

  ...

  let updateJob = (id, newJob) => {

    let new_jobs = jobs.slice();

    let job = new_jobs.uncover(j => j.id == id );

    job.helpful useful resource = newJob.helpful useful resource;
    job.start = newJob.start;
    job.end = newJob.end;

    setJobs(new_jobs);
    updateJobToAirtable(job);
  }

  if(property && jobs){
    return (
      most necessary>
        title>Gantt Chart/title>
        h1>Welcome to my Gatsby Gantt Chart/h1> 
        GanttChart jobs={jobs} property={property} onUpdateJob={updateJob}/> 
      /most necessary>
    )
  }else{
    ...
  }
}

Throughout the closing step, we have to implement the updateJobToAirtable function. As soon as extra, we observe the Airtable API documentation, this time throughout the half Substitute data:

function updateJobToAirtable(job){

    let data = {
      data: [
      {
        id: job.airtable_id,
        fields: {
          id: job.id,
          start: formatDate(job.start),
          end: formatDate(job.end),
          resource: [
            job.resource_airtable_id
          ]
        }
      }
    ]};

 fetch("XXX", {
    approach: "PATCH", 
    headers: {"Authorization": "ZZZ", "Content material material-Form": "software program/json"},
    physique: JSON.stringify(data)
  });
}

Now you can switch jobs throughout the Gantt chart and watch how the desk “Jobs” updates in precise time in your Airtable base.

Remaining Concepts

The easy job administration software program on this text reveals that server-side rendering can also be used for features with rich client-side interaction. The first profit is the fast preliminary loading time, on account of the DOM is prepared on the server. Significantly for features with a very difficult client interface (for example, dashboards for planning duties), this can be important. The periodical fetching of current data on the buyer side usually doesn’t end in principal effectivity points, on account of React makes use of a refined algorithm to seek out out which changes to the DOM are actually wanted.

The Gatsby framework drastically simplifies the tactic of making such hybrid features by providing seamless help for server-side rendering along with fairly a number of plugins for importing data from exterior sources.
