IMPORT REDIRECT

This is a tool to redirect the import specifier, it is used to transform the relative import path into a bare specifier.

BASIC USAGE

Suppose we have the directory structure below:

/PROJECT/index.ts        ->  import { vec2, vec3 } from './math/index';
        /math/.
        /math/index.ts    ->  export * from './vec';
        /math/vec.ts      ->  export const vec2, vec3;

const { ir } = require('import-redirect');

const code = ir.transformFileImport({
    file: '/PROJECT/index.ts',
    moduleIndex: '/PROJECT/math/index.ts',
    moduleName: 'MY_MATH_LIB',
});
console.log(code);  // import { vec2, vec3 } from 'MY_MATH_LIB';

FEATURE

• mergeSpecifier: merge multiple import statement with the same specifier.

const { ir } = require('import-redirect');

const code = ir.transformFileImport({
    file: '/PROJECT/index.ts',
    moduleIndex: '/PROJECT/math/index.ts',
    moduleName: 'MY_MATH_LIB',
    mergeSpecifier: true,
});
console.log(code);

// PROJECT/index.ts
import { vec3 } from './math/index';
import { vec2 } from './math/index';

code in PROJECT/index.ts should be transformed into:

import { vec2, vec3 } from 'MY_MATH_LIB';
