Cannot import .tsx file from .ts file (and vice versa)

Question

I have a project with .ts and .tsx files and I am trying to import a .tsx file from a .ts file, like so:

src/index.ts

import WriteEditor from './write_editor';

src/write_editor.tsx

import Events from './events';
import Actions from './actions';

export default class WriteEditor extends React.Component { /*...*/ }

Now TypeScript tells me

ERROR in ./src/index.ts Module not found: Error: Can't resolve './write_editor' in '/Users/luke/Projekte/writejs/code/writejs/src' @ ./src/index.ts 3:23-48 @ multi ./src/index.ts

So I tried this:

src/index.ts

import WriteEditor from './write_editor.tsx';

Now my IDE tells me not to write the extensions tsx and I get an errors in src/write_editor.tsx because TypeScript cannot find my .ts files from a .tsx file.

Then I went to rename the imports and added the .ts extensions

import Events from './events.ts';
import Actions from './actions.ts';

Now I am getting tons or errors telling me not to write extensions at all.

So how can we import tsx from ts and vice versa?

Answer 1

When you write

import WriteEditor from './write_editor';

Webpack will automatically look for

• ./write_editor
• ./write_editor.js
• ./write_editor.json
• (And a few others)

Since you're using .ts and .tsx, you need to tell it to look for those too in your Webpack config using resolve.extensions:

{
  resolve: {
    extensions: [".js", ".json", ".ts", ".tsx"],
  },
}
