browserify-livescript-middleware

The middleware to process livescript files into a single javascript file for Connect JS framework and by extension the Express JS.

LiveScript is a language which compiles to JavaScript. It has a straightforward mapping to JavaScript and allows you to write expressive code devoid of repetitive boilerplate. While LiveScript adds many features to assist in functional style programming, it also has many improvements for object oriented and imperative programming.

Check out livescript.net for more information, examples, usage, and a language reference.

Try

``text
$ npm install @tic-tac-toe/browserify-livescript-middleware
$ npm install express
$ PORT=8000 DEBUG=browserify-livescript-middleware node ./node_modules/@tic-tac-toe/browserify-livescript-middleware/examples/express.js
`

Then, open chrome with devtool to visit http://localhost:7000/view/example1, and see its source tab:

Usage

The middleware serves Livescript compilation, javascript bundling/compression, and static javascript files, so its usage is very simple. Just create a middleware instance with the given options:

- src directory of livescript source files
- dst directory of produced javascript files

Here is full example:

`javascript
var bls = require('@tic-tac-toe/browserify-livescript-middleware');
var app = express();
app.enable('trust proxy');
app.use('/js', bls({
src: ${__dirname}/scripts,
dst: '/tmp/work'
}));
app.listen(8000);
`

livescript-middleware? Why?

This project was originally forked from livescript-middleware. But, after making some changes, we found there are too many changes to be merged to original module. Then, we decided to create a new middleware to meet all of our requirements. Please see Why for more rationales.

Todos

- [ ] support koa2
- [ ] support fastly
- [ ] write a simple examples/express/index.js with ES6 to test/demonstrate this middleware
- [ ] test examples/koa/index.js with koa
- [x] use a forked livescript (https://github.com/ischenkodv/LiveScript/commit/7ae73cb263cb55ae32e44fddae81510aa4401679) with correct source map support (upgrade source-map-support from 0.3.2 to 0.5.11)
- [ ] move src/liveify to a standalone transform module, similar to liveify, maybe liveify-next`
