Prior to creating Jenkins jobs and Capistrano recipes you should prepare NodeJS dependencies and scripts. This article does not provide in-depth details about NodeJS.
The assumptions are that nodeunit is used for unit testing, forever for process management, and ExpressJS for creating a web server.
Step 1: Create a package.json file:
NodeJS dependencies and utility scripts can be configured through the package.json file. Below is an example of such a file:
{
"config": {
"unsafe-perm": true
},
"scripts": {
"test": "node_modules/.bin/nodeunit tests.js",
"start": "./node_modules/forever/bin/foreverd start app.js",
"stop": "./node_modules/forever/bin/foreverd stop app.js"
},
"dependencies": {
"express": "*",
"forever": "*",
"nodeunit": "^0.9.0"
}
}
More details can be found here: https://www.npmjs.org/doc/json.html and here: http://blog.nodejitsu.com/keep-a-nodejs-server-up-with-forever/
Step 2: Add some tests.js content (based on https://github.com/caolan/nodeunit):
exports.testSomething = function(test){
test.expect(1);
test.ok(true, "this assertion should pass");
test.done();
};
Step 3: Add a dummy app.js file (based on: http://expressjs.com/guide.html#intro):
var express = require('express');
var app = express();
app.get('/', function(req, res){
res.send('Hello World');
});
var server = app.listen(3000, function() {
console.log('Listening on port %d', server.address().port);
});
