すべての依存モジュールを開発版(リポジトリ)からインストールするように変更する

書き捨てです

do.js

var npm = require("npm")
var fs = require('fs')

getPackages(require('./package'), function(err, package){
    fs.writeFileSync('./package_new.json', JSON.stringify(package, null, '  '), {flag: 'w'})
})

function getPackages(package, cb){
    Object.keys(package["dependencies"]).map(function(p){
        fetchRepositoryURL(p, function (err, url) {
            package["dependencies"][p] = url
            cb(err, package)
        })
    })
}

function fetchRepositoryURL(name, cb) {
    npm.load({}, function (er, api) {
        api.commands.view([name], function(err, result){
            var p = result[Object.keys(result)[0]]
            if (p.repository) cb(null, p.repository.url)
        })
    })
}

node do.js
mv package_new.json package.json

npm API非依存版

ローカルに既にnode_modules/ がある前提のスクリプトも書いた。標準モジュールしか使ってないので ~/bin/rewrite_repo_urls.js とかで呼び出せる。

rewrite_repo_urls.js

#!/usr/bin/env node

var fs = require('fs');
var exec = require('child_process').execSync;

var myPackage = require(process.cwd() + '/package');

var paths = exec('find ./node_modules -type f -depth 2 -name package.json').toString().split("\n");
paths.map(function(path){
    if(path.length === 0){
        return;
    }

    var name = /node_modules\/(.+)\/package.json/.exec(path)[1];
    var package = require(process.cwd() + '/' + path);
    if(myPackage['dependencies'][name] && package.repository){
        myPackage['dependencies'][name] = package.repository.url;
    }
});

fs.writeFile('./package.json', JSON.stringify(myPackage,  null, '  '), {flag: 'w'});
