How to Create a Basic Gantt Chart with Salesforce Lightning [Video Guides]


If you’re developing a project management application based on the Salesforce Lightning platform, you probably use the Lightning Web Components (LWC) that significantly simplify and accelerate the process of building responsive applications for any device. But any modern project management app can hardly be good enough for achieving complex business objectives without a Gantt chart functionality. And the good news is that you can easily integrate the DHTMLX Gantt chart with Salesforce Lightning components into your app.

In this post, we’d like to share with you a code example on GitHub and two video guides on how to use our Gantt component with Salesforce in your project.

Why Use Lightning Web Components for Creating Your Salesforce App?

Salesforce has become widely recognized in the software industry as a global leader in cloud-based CRM technologies, but the company is also known for its innovative solutions for front-end development such as Lightning Web Components (LWC). This modern JavaScript programming model helps to create high-performant Salesforce apps that run on modern web browsers using the latest web/W3C standards and the newest JavaScript features.

In essence, LWCs are custom elements built using HTML and ES6+ standards. Introduced at the end of 2018 as a more advanced alternative to the older model named Aura components, LWC has become a great possibility for millions of JS developers around the globe to write code on the Lightning Platform in a much easier way. The thing is that developers don’t need to learn any new frameworks to work with LWC but can use standard tools (HTML, CSS, JS), thus the whole development process becomes much simpler and faster.

Using DHTMLX Gantt for Implementation of Gantt Chart Functionality

DHTMLX Gantt is a comprehensive JavaScript library that enables developers to build Gantt charts of any complexity level complemented with numerous useful features (critical path, resource management, auto-scheduling, etc.) and make use of advanced customization capabilities. But most importantly, our Gantt component can be smoothly and securely integrated with Salesforce without any compatibility issues.

Video Guide on Adding DHTMLX Gantt into Salesforce LWC

When it comes to embedding our Gantt library into Salesforce, you have nothing to worry about, as our detailed video guide vividly demonstrates each step of the process.

Before starting you should install the Salesforce CLI for convenient coding. We also recommend installing the Salesforce Extension Pack to Visual Studio Code which enables you to work with development orgs.

Alternatively, you can also make use of the guide provided in the Gantt documentation for achieving the same goal. The guide includes detailed explanatory notes with code and images on all stages of adding our Gantt component into Salesforce LWC. In addition, the tutorial offers helpful commentaries on two important topics such as applications security and troubleshooting.

In our GitHub repository, you can find a ready-made DHTMLX Gantt demo for SalesForce with the complete source code.

DHTMLX Gantt Integration with LWC (Installation Guide)

One more significant aspect of using DHTMLX Gantt in Salesforce is making necessary adjustments in Salesforce settings for running the Gantt project. This procedure is highlighted in another step-by-step video tutorial.

Please note that the given tutorial requires an additional step. You will need to create a custom lightning tab with Gantt. You can see how it is done in this part from the first video guide or check out this step in the GitHub repository.

Apart from the Salesforce CLI, you’ll also need to enable the Developer Hub that serves for creating and managing scratch orgs. After that, just follow the instructions, and very soon you will get the desired result.

So you get everything you need for building yourown Salesforce application with DHTMLX Gantt. What’s next? Visit our GitHub repository where you can find the full source code of our Gantt component with Salesforce and follow the steps of our video guide.
