BEMongo-stub

Why?

When I began to study methodology BEM and its tools, it was difficult to find any actual examples of project making. To solve this problem, I wrote a small project that shows how to bring the data source (in this case mongodb) to the BEM-stack.

What is BEMongo-stub?

It's a template repository to create your own BEM-project with mongodb. It has the essential functionality, including the application framework to obtain & store data in mongodb. Also I made user authorization using OAuth 2.0 API Yandex.

Used BEM-libraries for a project:

• bem-core
• bem-components

Implementation features

• Express -- used for the proper project routing;
• MongoDB -- data storage (we'll take from here :) ). I used mongodb in conjunction with the bluebird promises;
• ENB -- a tool that builds the bundles;
• [Passport Yandex](https://github.com/gurugray/passport yandex) -- authentication in the project can be accomplished through the OAuth 2.0 API Yandex.

Essentially the project is divided into 2 parts:

• server -- the server part;
• static -- the blocks and the bundles of the pages. For the blocks implementation I used priv.js, because the data will be taken dynamically.

Installation requirements

• Node.js 0.10+ is a software platform based on JavaScript that allows you to create fast, scalable network applications;
• Git Bash – for the Windows OS users.

Setup

Clone the repository and install all the required dependencies:

git clone git@github.com:evilj0e/bemongo-stub.git my-bem-project
cd my-bem-project
npm run init # do Not use root (`root`) when you install npm and bower dependencies.

Bower dependencies are installed when you run npm run init to /static/vendors.

In order to use the OAuth 2.0 API by Yandex you need to get the Client ID & Client secret keys for your own app. You can do it here. After that you need to change the config file for passport server/lib/passport.js:

passport.use(new PassportYandex({
        clientID: '--- Client ID ---',
        clientSecret: '--- Client secret ---',
        callbackURL: 'http://localhost:3000/login/callback'
    },
    function(accessToken, refreshToken, profile, done) {
        process.nextTick(function () {
            db.upsertUser(profile.id, profile, done);
        });
    }
));

Build and run the project

You can build a project using ENB. You can run commands enb from the folder node_modules/.bin/enb or you can use my shortcuts.

Available shortcuts

init -- initialization of the project and installation of all dependencies;

jscs -- checks codestyle with jscs;

jshint -- checks codestyle with jshint;

csslint -- checks codestyle with csslint;

codestyle -- executes checks with jscs, jshint, csslint. Used as pre-commit hook;

test -- it doesn’t make anything so far, because I haven’t written tests yet (lol);

server -- builds project and runs a development server;

serverOnly -- just runs a development server.

After running a development server, project will be available at http://localhost:3000. Press the key combination Ctrl + C or ⌘ + C (for MAC) in the active terminal window to stop the server.

Shortcuts are invoked in the project folder as follows:

npm run %command_name%

%command_name% -- the name of the shortcut

TODO

• To rewrite controllers/db;
• To remake authorization redirects from / to requested url & don't use forced authorization on some pages;
• To write tests;
• To make CI integration;
• To make the logging;
• To add the Helmet;
• To add the Recluster;
• To add an example of the block templating on the client.
