Tiny little connect middleware to mount and auto-deploy apps from a git repository. Pretty cool.
$ npm install connect-girrorThe sample below "mounts" the github repository https://github.com/eladb/foo into the /foo
route on the connect/express server. When the program is started, girror is used to
checkout a local copy of this repository and spinner is used to spawn app.js from
this repository and keep it alive. HTTP requests into this route are proxied
using http-proxy into the child app.
var connect = require('connect');
var girror = require('connect-girror');
var app = connect.createServer();
app.use('/foo', girror('https://github.com/eladb/foo'));
app.get('/', function(req, res) {
res.end('Nothing to see here. Try /foo\n');
});
app.listen(5000);A working example is available under samples (start with node server).
connect-girror implements a simple POST endpoint which triggers redeployment when invoked.
This is commonly used to serve git post-receive hook such as github's.
To set up the hook, just pass the { hook: '/path/to/secret/endpoint' } option when calling the middleware:
app.use('/foo', girror('https://github.com/eladb/foo', { hook: '/bhmn489dkjh8m' }));Then, any HTTP POST request sent to /foo/bhmn489dkjh8m will trigger a redeployment.
connect-girror supports arbitrary post-deployment handlers via the build option.
The default handler will execute npm install if package.json exists in the root of the
fetched repository (and npm is installed).
var exec = require('child_process').exec;
var foo = girror('https://github.com/eladb/foo', {
hook: '/bhmn489dkjh8m'
build: function(dir, callback) {
console.log('foo was just updated! horray!');
return callback(); // first argument can be an error which will fail the deployment
}
});remote is any legit git URL (e.g. https://user:password@github.com/account/repo, git@github.com:account/repo.git,
file:///repo/file/system/path). Any credentials must be supplied in case they are not implicitly installed on the machine.
options.main is the app's file name. Defaults to app.js.
options.hook is the relative URL of the deployment hook endpoint. Any HTTP POST requests sent to this hook will cause a re-deployment. Use some form of obscure key for security.
options.build is a function(callback) which is called after deployment. callback is a function(err) that should be called when the build process is over. The default is to run npm install in the working directory in case there is a package.json file and npm is installed.
options.verbose can be set to true for maximum log verbosity. Otherwise, only errors and warnings will be emitted.
