Typescript "cannot find module <module>" error using ES6 modules

Question

I have a file in src/shared/components/A.tsx that does import B from 'components/B' (src/shared/components/B.tsx)

Typescript gives me an error cannot find module 'components/B'

This is my tsconfig.json file which is in the root directory:

{
  "compilerOptions": {
      "outDir": "./dist/",
      "sourceMap": true,
      "module": "es6",
      "target": "es6",
      "jsx": "react",
      "allowJs": true,
      "moduleResolution": "node"
  },
  "include": [
      "src/**/*"
  ],
  "exclude": [
      "node_modules"
  ],
  "baseUrl": ".",
  "paths": {
      "*": [
        "*",
        "src/shared/*" //this doesn't seem to work
      ]
  }
}

My understanding from https://www.typescriptlang.org/docs/handbook/tsconfig-json.html is that it will try to find ./components/B first, which does not exist, then go into <baseUrl>/src/shared/components/B, which is where the file exists, so I'm not sure why I'm still seeing an error.

Out of curiosity - if you rename the .jsx file to a .js file, does that work? If you explicitly import with .jsx as a suffix, does that fix it? — Daniel Rosenwasser

It worked before I ported to typescript and if I change the file extension Typescript won't throw errors in the file. However, module B has errors in the code which would prevent it from compiling... Does typescript attempt to compile modules that are imported into a file? — PDN

Well this was silly, paths / baseUrl belong inside compilerOptions.
