I’m currently working on a javascript project. I usually use typescript and ts has the path mapping feature. Is there something similar in javascript ?

TS path mapping:

"compilerOptions": {
        "baseUrl": "src",
         ...
        "paths": {
            "@app/*": ["app/*"],
            "@config/*": ["app/_config/*"],
            "@environment/*": ["environments/*"],
            "@shared/*": ["app/_shared/*"],
            "@helpers/*": ["helpers/*"]
        },
        ...

>Solution :

In Webpack this feature is available via resolve.alias. The configuration is similar, for example via webpack.config.js:

const path = require('path');

module.exports = {
  resolve: {
    alias: {
      "@app": path.resolve(__dirname, 'app/'),
      "@config": path.resolve(__dirname, 'app/config/'),
      "@environment": path.resolve(__dirname, 'environments/'),
      // Etc
    },
  },
};
