dist-js

Create dist version of your JS.

Combines tools for adding comptibility and optimizations to your JS compiler's output.

$ dist-js dist/app.js

This will

• Run babel with babel-preset-env.
• Run uglify-es.
• Use sourcemaps when given input and output paths.

Also see dist-css for your CSS files.

Install

$ npm i -D dist-js

dist-js [file] [...options]

The easiest way to use the tool is transforming a file in place:

$ dist-js dist/app.js

It will also detect when you want to use stdio:

# Using stdout
$ dist-js dist/app.js | wc -c
6780

# Using stdin
$ echo "console.log(1 + 2)" | dist-js dist/app.js
finished dist-js at dist/app.js

# Using both
$ echo "1 + 2" | dist-js > dist/app.js

Alternative to this, use the --input, -i and --output, -o flags, where if a flag is absent it uses the stdio equivalent instead.

Also note that you can only accept a sourcemap with an input path, and write a sourcemap with an output path. Inline sourcemaps are not supported out of simplicity.

To disable sourcemaps regardless, supply the --no-sourcemap flag:

$ dist-js --no-sourcemap dist/app.js
