A TypeScript transformer which enables transformation of absolute imports (using baseUrl or paths) to relative ones, so they can be required from other projects or regular ol' node.
Read more about why this exists and what problem it solves
TypeScript >= 2.4.1
Unfortunately, TypeScript itself does not currently provide any easy way to use custom transformers (See microsoft/TypeScript#14419). The followings are the example usage of the custom transformer.
See examples/ttypescript for detail, and ttypescript's README for how to set up in your project.
// tsconfig.json
{
"compilerOptions": {
// ...
"plugins": [
{ "transform": "ts-transformer-imports" }
]
},
// ...
}See test for detail.
You can try it with $ npm test.
const ts = require('typescript');
const importsTransformer = require('ts-transformer-imports').default;
const program = ts.createProgram([/* your files to compile */], {
strict: true,
noEmitOnError: true,
target: ts.ScriptTarget.ES5
});
const transformers = {
before: [],
after: [importsTransformer(program)]
};
const { emitSkipped, diagnostics } = program.emit(undefined, undefined, undefined, false, transformers);
if (emitSkipped) {
throw new Error(diagnostics.map(diagnostic => diagnostic.messageText).join('\n'));
