tsify

Browserify plugin for compiling TypeScript

Example Usage

Browserify API:

var browserify = require('browserify');
var tsify = require('tsify');

browserify()
    .add('main.ts')
    .plugin('tsify', { noImplicitAny: true })
    .bundle()
    .on('error', function (error) { console.error(error.toString()); })
    .pipe(process.stdout);

Command line:

$ browserify main.ts -p [ tsify --noImplicitAny ] > bundle.js

Note that when using the Browserify CLI, compilation will always halt on the first error encountered, unlike the regular TypeScript CLI. This behavior can be overridden in the API, as shown in the API example.

Installation

Just plain ol' npm installation:

1. Install browserify

npm install browserify

2. Install tsify

npm install tsify

For use on the command line, use the flag npm install -g.

Options

• tsify will generate sourcemaps if the --debug option is set on Browserify.
• tsify supports almost all options from the TypeScript compiler. Notable exceptions:
  • -d, --declaration - See tsify#15
  • -m, --module - This is defaulted to CommonJS automatically (or None when in ES6 mode).
  • --out, --outDir - Use Browserify's file output options instead. These options are overridden because tsify writes to an internal memory store before bundling, instead of to the filesystem.
• tsify supports the following extra options:
  • --typescript - This allows you to pass in a different TypeScript compiler, such as NTypeScript. When using the API you can either pass in the name of the alternative compiler or a reference to the compiler.

does this work with...

tsconfig.json?

tsify will automatically read options from tsconfig.json. However, some options from this file will be ignored:

• compilerOptions.declaration - See tsify#15
• compilerOptions.module - This is defaulted to CommonJS automatically (or None when in ES6 mode).
• compilerOptions.out and compilerOptions.outDir - Use Browserify's file output options instead. These options are overridden because tsify writes to an internal memory store before bundling, instead of to the filesystem.
• files - Use Browserify's file input options instead. This is necessary because Browserify needs to know which file(s) are the entry points to your program.

Watchify?

Yes! tsify can do incremental compilation using watchify, resulting in much faster incremental build times. Just follow the Watchify documentation, and add tsify as a plugin as indicated in the documentation above.

Gulp?

No problem. See the Gulp recipes on using browserify and watchify, and add tsify as a plugin as indicated in the documentation above.

Grunt?

Use grunt-browserify and you should be good! Just add tsify as a plugin in your Grunt configuration.

IE 11?

The inlined sourcemaps that Browserify generates may not be readable by IE 11 for debugging purposes. This is easy to fix by adding exorcist to your build workflow after Browserify.

Why a plugin?

There are several TypeScript compilation transforms available on npm, all with various issues. The TypeScript compiler automatically performs dependency resolution on module imports, much like Browserify itself. Browserify transforms are not flexible enough to deal with multiple file outputs given a single file input, which means that any working TypeScript compilation transform either skips the resolution step (which is necessary for complete type checking) or performs multiple compilations of source files further down the dependency graph.

tsify avoids this problem by using the power of plugins to perform a single compilation of the TypeScript source up-front, using Browserify to glue together the resulting files.
