4 Steps to Add Custom Language Support to Monaco Editor

In many services where we need to provide users with the ability to write code, we need to provide users with an editor that is powerful enough to make writing code smoother, reduce the number of document queries, reduce the probability of errors, and improve coding efficiency.

To provide these capabilities, we need a powerful enough code editor and add our custom language support to it, so that users can get enough support in syntax highlighting, autocomplete, etc.

Why Monaco Editor?

Visual Studio Code is a very popular code editor in the world, and the Monaco Editor is the code editor used to build the core functionality of VSCode, which provides quite a lot of features for implementing various code editing capabilities. And Microsoft provides a standalone project for Monaco Editor, with a separate packaging script, so we can easily integrate Monaco Editor into our own web applications.

The Monaco Editor already provides a series of infrastructure to complete the support for custom languages, and in a few small steps, we can build a code editor with our own language support.

So, let’s get started!

Step 1. Register a Language

Here we will not go over how to introduce the Monaco Editor into the web application, instructions for integrating Monaco Editor in various ways are provided in the Monaco Editor repository.
