gulp-create-tsindex

This gulp plugin will join your typescript files into one export file.

Installation

Install gulp-create-tsindex using npm into your local repository.

npm install gulp-create-tsindex --save-dev

Usage

Extend your typescript gulp task to create a index file.

var gulp = require('gulp');
var ts = require("gulp-typescript");
var tsindex = require('gulp-create-tsindex');
 
var tsProject = ts.createProject('tsconfig.json');
 
gulp.task('build-typescript', function () {
    return gulp.src('./src')
        .pipe(tsindex('./src/index.ts'))
        .pipe(ts(tsProject));
        .pipe(gulp.dest('dist'));
});

This will create a file index.ts and inject it into the typescript build.

Example index.ts:

export * from "./file_A";
export * from "./file_B";
export * from "./file_C";

Don't want to expose all files?

You can ignore typescript files to be added in the index, and thereby making the exports in that file "package-scoped".

To achieve that, use the token "/// tsindex:ignore" in the source file, which needs to be ignored. The file content must start with the ignore token, as shown in the example below.

/// tsindex:ignore
import { stuffs } from "somepackage1"
...
 
export class MyInternalStuffInPackage{
...
}

If you don't like the default token, you can configure it via build task:

tsProject.src()
    .pipe(tsindex(paths.src + '/index.ts',{ignoreToken:"/// my_custom_token"}))
    ...

Note that this is optional; however, in this case, the token /// my_custom_token needs to be used in the source file instead.

This strategy is too simple for you? Let us know.
