Why node-packager?
Use node-packager
to generate the built package for your library or application.
It's ideal for applications that builds packages on the fly using Node.js.
Usage
package.js:
function Package() {}
extend( Package.prototype, {
// Shallow copy
"LICENSE.txt": "LICENSE.txt",
// Sync processing
"app.css": function() {
// Return a String or Buffer with the file data.
return buildCss();
},
// Async processing
"app.js": function( callback ) {
// Call `callback( error, data )`, where data is a String with the file data.
buildJs( callback );
},
"images/": function() {
var files, imagesFiles;
// this.files and this.runtime are available.
if ( this.runtime.includeImages ) {
files = this.files;
imagesFiles = {};
Object.keys( this.files ).filter(function( filepath ) {
return minimatch( filepath, "src/images/*" );
}).forEach(function( filepath ) {
imagesFiles[ path.basename( filepath ) ] = files[ filepath ];
});
return imagesFiles
}
// Skip "images/" by returning null.
return null;
}
});
module.exports = Package;
npm install node-packager
var fs = require( "js" );
var glob = require( "glob" );
var extend = require( "util" )._extend;
var Package = require( "./package" )
var Packager = require( "node-packager" );
var files = glob.sync( "+(LICENSE.txt|src/**)", { nodir: true } ).reduce(function( files, filepath ) {
files[ filepath ] = fs.readFileSync( filepath );
return files;
}, {} );
var pkg = Packager( files, Package, {
includeImages: true
});
var stream = fs.createWriteStream( "myapp.zip" );
pkg.toZip( stream, function( error ) {
if ( error ) {
return console.error( error );
}
console.log( "Built myapp.zip (" + pkg.stats.toZip.size + " bytes) in " + ( pkg.stats.build.time + pkg.stats.toZip.time ) + " ms" );
console.log( "- app.js took " + pkg.stats[ "app.js" ].time + " ms" );
});
