You need to write a parser / lexer and implement basic functionality like code completion. Full language support requires a lot of work. You need to specify a place for execution of the tool and write simple code to run the tool and parse the results. Usually, integration with external tools isn’t a big deal. If a framework extends some existing functionality, supporting it is relatively easy. Depending on the framework, adding support for it can be similar to supporting a new language. There are different types of plugins that we can build: Let’s get started with building our first plugin.

Step 1: Decide on what plugin you want to build Second, Kotlin, which can be also used for writing plugins, is syntactically similar to TypeScript. First, you can build some plugins without writing any code, and we’ll see how in a moment. There’s some good news for those who don’t know Java. If not, then you can try building a plugin. It may be available out of the box or as a plugin in our marketplace. So, where do you start if you’re interested in building a plugin? First of all, double-check whether the functionality you’re looking for already exists. For example, the Import Cost plugin runs the import-cost npm package under the hood. You can use JavaScript-based integrations in plugins, though. Because of this, you can’t build plugins for them using JavaScript or TypeScript. Both the IntelliJ Platform and WebStorm are JVM applications, written mostly in Java and Kotlin. Like all other JetBrains IDEs, WebStorm is built on top of the open source IntelliJ Platform.

In part 2 and part 3 of this series, we’ll build more complex things.

In this part, we’ll cover some basic concepts for developing plugins for WebStorm and show you how to build a simple plugin without writing any code. Where do you start? How to work through if you don’t know any Java? We’ll try to answer these questions by walking you through the process of building three plugins for WebStorm.

There are thousands of open APIs for extending our IDEs and dozens of ways to do one simple task for a plugin.

This documentation is written for those who understand basic Java concepts.

There’s comprehensive documentation on plugin development, however: If you’ve ever wondered how to build a plugin for WebStorm or any other JetBrains IDE, you might know it’s not an easy task.
