metamorph

Morphs package meta files into each other.

Currently supports: npm, jamjs, component.

Using Globally

Install globally with: npm install metamorph -g

metamorph component.json jam will generate a jam compatible package.json meta file.

Specify a 3rd arg to change the output filepath: metamorph package.json component /some/path/component.json

Using Locally

Install with: npm install metamorph --save

var metamorph = require('metamorph');
var fs = require('fs');
 
// convert a component.json into a jam compatible package.json
metamorph('component.json', 'jam', function(err, data) {
  fs.writeFileSync('package.json', data);
});
 
// and back again
metamorph('package.json', 'component', 'component.json');

Feed it missing/override data:

var metamorph = require('metamorph');
 
var data = { repo: "shama/custom" };
metamorph('package.json', 'component', data, function(err, p) {
  console.log(JSON.parse(p).repo); // === 'shama/custom'
});

Stream

var metamorph = require('metamorph');
var fs = require('fs');
 
var mm = metamorph('component.json', 'jam');
mm.pipe(fs.createWriteStream('package.json'));

var Metamorph = require('metamorph').Metamorph;
var fs = require('fs');
 
var mm = new Metamorph('component');
fs.createReadStream('package.json')
  .pipe(mm)
  .pipe(fs.createWriteStream('component.json'));
