What steps are needed to enable WebStorm's autocompletion for external libraries?

As a beginner user of WebStorm and TypeScript, I am currently experimenting with incorporating the libstl library into my code. The snippet below is what I have written so far:

var PriorityQueue = require('libstl').PriorityQueue;

var queue = new PriorityQueue();

While I can compile this to JavaScript without any errors, I am facing an issue where the autocompletion feature does not suggest the methods available for the variable queue, such as enqueue() or dequeue().

Is there a way for me to configure WebStorm to recognize this library and provide autocompletion support for its methods?

Answer №1

After adding the libstl library to my project with npm install libstl --save, I found that completion works smoothly in JavaScript files. However, when working with TypeScript in WebStorm, it seems to have trouble resolving CommonJS calls and recognizing the 'require()' function without the node.d.ts file present.

In light of this, I recommend using TypeScript syntax in .ts files and sticking to JavaScript in .js files. For instance, consider updating your code like this:

import PriorityQueue = require('./node_modules/libstl/Datastructures/PriorityQueue')

var queue = new PriorityQueue();
