When I set up typings to run with typescript, I got stuck for a while trying to get imports from external libraries to work, with this error:
typings/main/definitions/react/index.d.ts(2322,5): error TS2666: Exports and export assignments are not permitted in module augmentations.
This happens, for instance, trying to use React:
import * as React from 'react';
interface IMessage {
msg: String;
}
class TestApp extends React.Component {
public render(): Element {
return test;
}
}
The reason for this is you need use a special incantation to install libraries:
typings install react --ambient --save
In order for this to work without weird reference comments in the file, you also need a tsconfig.json:
{
"compilerOptions": {
"module": "commonjs",
"target": "es5",
"jsx": "react",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"outDir": "dist"
},
"exclude": [
"node_modules",
"dist",
"node_modules",
"typings"
],
"files": [
"./app/index.tsx",
"./typings/main.d.ts"
]
}
