As a vision user I want to see a list of projects So that I can select a project I want to monitor
Let's add a test to ./test/project.js for our feature List projects. This resource will GET all projects from route /project and return a 200 Ok status.
describe('when requesting resource get all projects', function(){
it('should respond with 200', function(done){
request(app)
.get('/project/?user=' + login.user)
.expect('Content-Type', /json/)
.expect(200)
.end(function (err, res) {
var proj = _.first(JSON.parse(res.text))
assert(_.has(proj, '_id'));
assert(_.has(proj, 'name'));
assert(_.has(proj, 'user'));
assert(_.has(proj, 'token'));
assert(_.has(proj, 'created'));
assert(_.has(proj, 'repositories'));
done();
});
});
});Let's implement the List projects feature ./lib/project/index.js and add an all function. We attempt to retrieve all projects by calling the static function Project.find and querying by a user id. If we get an error we return it, if we find the projects, we return the projects:
Project.prototype.all = function(id, callback){
var query = {"user" : id};
ProjectSchema.find(query, function(error, projects) {
if (error) return callback(error, null);
return callback(null, projects);
});
};Let's add a new route ./lib/routes/project.js. We start by defining a route called all. We start by retrieving a users id. In order to accommodate the fact that we have not implemented an authentication strategy; we get the user details from our hard-coded login.user object. We will clean this up in a future chapter. We attempt to retrieve a project by calling Project.all, passing the userId. If we get an error, we return 500 Internal Server Error; if we find projects, we return the projects and a 200 OK response.
exports.all = function(req, res){
logger.info('Request.' + req.url);
var userId = login.user || req.query.user || req.user.id;
Project.all(userId, function(error, projects) {
if (error) return res.json(500, 'Internal Server Error'),
if (projects == null) projects = {};
return res.json(200, projects);
});
};Now, add the following route to the Express server ./lib/express/index.js:
app.get('/project', project.all);
