What is the best way to set up TypeScript to utilize multiple node_modules directories in conjunction with the Webpack DLL plugin?

Utilizing Webpack's DllPlugin and DllReferencePlugin, I create a distinct "vendor" bundle that houses all of my main dependencies which remain relatively static.

The project directory is structured as follows:

project
  App
    (code and components)
  tsconfig.json
  package.json
  node_modules
  vendor
    package.json
    node_modules

In transitioning from Flow to TypeScript, I previously had this configured in my .flowconfig:

[options]
module.system.node.resolve_dirname=node_modules
module.system.node.resolve_dirname=vendor/node_modules

Currently, Visual Studio Code is displaying numerous errors because TypeScript is unaware of vendor/node_modules.

How can I set up the same configuration in tsconfig.json so that TypeScript can recognize all of these libraries?

Answer №1

After some experimentation, I managed to achieve this using the paths parameter within the compilerOptions section of my tsconfig.json file:

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "*": ["node_modules/*", "vendor/node_modules/*"]
    },

This configuration is similar to the resolve_dirname options in my .flowconfig settings:

[options]
module.system.node.resolve_dirname=node_modules
module.system.node.resolve_dirname=vendor/node_modules
