JS Squish

Concatenates a bunch of Javascript files together into a single deployable source file. It's like Browserify, but faster.

Right now, this acts as a stand-alone binary with a rule implementation, but once we have something substantial building with it, build should live in @io_bazel_rules_js//js/tool.

CLI Usage

From the command line, jssquish takes a js_tar and entrypoint, and creates an output file. For more information on what a js_tar is, see the README for //tool/build_rule/rules_js.

```sh
bazel run //tool/js-squish -- -h
Usage of js-squish:
  -entrypoint string
      Entrypoint (default "index.js")
  -jstar string
      Path to JSTar
  -output string
      Squished JS Output
```

Build artifact usage

To generate js-squish'd files, include the rule file included in this module and use the js_squish rule.

```python
load('@io_bazel_rules_js//js:def.bzl', 'js_binary')
load('//tool/js-squish:rules.bzl', 'js_squish')

js_binary(
  name = 'my-prog',
  src  = 'cool_proj.js',
  deps = ['@react//:lib'],
  main = 'my/cool/prod',
)

js_squish(
  name = 'my-prog.dist',
  src  = ':my-prog',
)
```

This will create a build artifact named my-prog.dist.js
