It's just a wrapper to build Stream transformers with functional style. It's like the koa / expressjs middlewares !
const ezs = require('ezs')
ezs.use(require('ezs-basics'));
process.stdin.resume();
process.stdin.setEncoding('utf8');
process.stdin
.pipe(ezs('split', { delimiter: "\n" }))
.pipe(ezs('counter'))
.pipe(ezs(function(input, output) {
output.send(input.toString();
})
.pipe(process.stdout);
With npm:
$ npm install ezs
Use mocha to run the tests.
$ npm install mocha
$ mocha test
Converts a transform stream with existing function or adhoc function.
const ezs = require('ezs'),
let trasnformer = ezs(function(input, output) {
output.send(input.toString())
})Each statement function have its own scope and can access to few methods :
- this.isLast()
- this.isFirst()
- this.getIndex()
- this.getParam(name, defaultValue)
- this.getParams()
Output object is an object with few methods :
- output.write(something)
- output.end()
- output.send(something)
- output.close()
Adding bundle of statements. see the avaible modules here : https://www.npmjs.com/browse/keyword/ezs
var ezs = require('ezs'),
ezs.use(require('ezs-basics'));
ezs.use(require('ezs-files'));
