Quantified Self Webpack
To get you started building your Quantified Self app.
Initial Setup
One person from your project will set up the repository. That one person should follow these steps:
- Clone this starter kit repository and rename the repository to
quantified-self
in one command
git clone git@github.com:turingschool-examples/quantified-self-starter-kit.git quantified-self
-
Change into the
quantified-self
directory -
Remove the default remote (origin)
git remote rm origin
-
Create a new repository on GitHub named
quantified-self
-
Add your new repository remote - your remote URL and user name will be different in the command below
git remote add origin git@github.com:neight-allen/quantified-self.git
- Install the dependencies of the starter kit
npm install
- Add, commit, and push up to your repository
git add .
git commit -m "Initial commit using starter kit"
git push origin master
-
Now add your team member(s) as collaborators to the repository. They can now clone down your
quantified-self
repository as normal. -
Once each partner clones down the repo, they need to run
npm install
to install the dependencies on their machine.
Github Pages setup
-
Visit your repository on Github
-
Go to Settings
-
Under the Github Pages section of Options, select 'master' as your source
Be sure to npm run build
and commit before each push to master. A few seconds after you push up, you should be able to see your application at https://your-github-username.github.io/quantified-self.
Run the Server
To see your code in action, you need to fire up a development server. Use the command:
npm start
Once the server is running, visit in your browser:
http://localhost:8080/webpack-dev-server/
to run your application.http://localhost:8080/webpack-dev-server/test.html
to run your test suite in the browser.
To build the static files. This must be done before committing and pushing if you want your site to work at github.io:
npm run build
Run Tests in the Terminal
To run all of your tests:
npm test
File Organization
Webpack is a little opinionated about how files are organized. Here is a brief guide on how to organize development and test files.
Development Files
Node and webpack work together to help us organize our files and keep responsibilities separated.
For example, if we have the lib/index.js
file and a lib/food.js
file:
lib/index.js
var Food = require('./food');
var someFood = new Food();
lib/food.js
function Food(food, calories) {
this.name = name;
this.calories = calories;
}
Food.prototype.edit = function () {
//Some cool storage stuff here
};
module.exports = Food;
All of the food.js
code could live in the index.js
file, but that would go against our philosophy of separating responsibility between files.
There are two main things to pay attention to here:
-
At the top of the
index.js
file, we require thefood.js
file using the line of codevar Food = require('./food');
(we leave out the.js
). This brings in the code from thefood.js
file so we can use that file's code in theindex.js
file. -
In the
food.js
file, the bottom line saysmodule.exports = Food;
which says what we want this file to export when we sayrequire
in other files, like inindex.js
.
So now we have two files that can share code between each other, but we have to pay attention to what we export and what we require. If we didn't do this, then when we try to make a new Food in the index.js
file, it won't know what Food we're talking about!
Test Files
Near the end of quantified self, you will have multiple objects for your project that are tested separately with individual test files. The test/index.js
file serves as an "entry point" for mocha to load all of the tests you write.
Test file organization is a bit different from development files. If we want to test the food.js
file from above, then this is how we would do it. For each object file (in this case food.js
), we want to have a corresponding test file. So in the test
directory, we would create a new file called test/food-test.js
. Here is what that file would look like:
test/food-test.js
var chai = require('chai');
var assert = chai.assert;
var Food = require('../lib/food');
describe('Food', function() {
context('can create a new food', function() {
// Your tests here...
});
});
test/index.js
require('./food-test')
Two main points to pay attention to:
-
In the
food-test.js
file, we require thefood.js
file so that we can construct foods in our tests. -
In the
test/index.js
file, we require thefood-test.js
file so that we can view the test results in the browser (athttp://localhost:8080/webpack-dev-server/test.html
). But most of the time, you'll just run your tests in the terminal withnpm test
