A boilerplate project for writing applications using Koa2 and React

What?

I became disillusioned with frameworks for Node.js, so here is a comprehensive MVC boilerplate project with most of the modern application components implemented in a consistent code style without any frameworks (well, on backend anyway). Note that this stack assumes you have intermediate to advanced understanding of Node.js. It is not for beginners.

Stack supports

• Koa2 (i.e. async await - you need Node.js 7.6, 8+ highly recommended for debugging with inspector protocole)
• React for frontend using Webpack
  • Modules
  • Async functions
• Gulp asset pipeline (disabled by default - may conflict with some of the ports webpack uses)
• MongoDB
• MariaDB/MySQL
• Migrations
• SASS css preprocessor (uses .scss syntax by default)
• Basic security (CSRF)
• Both ejs and pug view engines

How?

Get started with

git clone https://github.com/megakoresh/koa2-react.git yourprojectname
cd yourprojectname
rm -rf .git
git init .

You now have the code base for a new project. The base classes are documented as to what they do. Project is meant to allow easy extensibility without breaking code style. You might want to

• Inject ORM (e.g. Sequelize or Mongoose) - wrap it with Database class methods, or Model class methods, then extend from it.
• Security - place it in middleware package, then use where needed
• Policies - Add them as static methods to Authenticator, then use them when setting routes in controllers
• Foundation/Bootstrap - see comments in webpack config
• Migrations - npm install -g db-migrate and db-migrate create:sql my-new-migration -e test-maria, see https://db-migrate.readthedocs.io/en/latest/ for details
• Global configuration - place it to common package where appropriate, then require. For database-related things, place to database package
• File uploads - set the {multipart: true} option for the bodyparser

I highly recommend you use Visual Studio Code for developing Node.js applications and this one in particular. It already includes launch configurations for both frontend and backend debugging, and in general VSCode is nowadays the best Node.js development IDE. You will save a lot of time with it.

Why?

I have used Sails.js for a long time, and in every single project, I spent more time fighting Sails and specifically - Waterline than building the actual application. I have used Meteor several times, and in every project when I wanted to change small details that made a lot of difference, I found it was impossible because "That's not how Meteor works". Same thing with Hapi. In the end, when you are building a more or less unique project (i.e. not yet another blog or web store or another kind of template site), you'll run into the framework's limitations sooner rather than later. Yes, building something without framework makes it more verbose, but with modern Javascript techniques and consistent code conventions that can be an avantage as well.

This project aims to give you a quick start by eliminating the tedium of setting up an application, as well as providing you with a reasonably flexible, yet consistent and robust coding style and architecture with proper error handling and an example of every boilerplate feature both in implementation and usage. It is not a generic solution that will cover every possible use case. It is a solution that will help cover your use case.

FAQ

• Why does it not have [insert feature x here]?
  • Because not everyone needs it. It is probably fairly straighforward to add this feature though.
• I found a design problem/bug/suggestion
  • Put it to issues.
• What would be the recommended way of adding feature X?
  • If it's not obvious and the feature is not very niche, then it's a design flaw, put the question to issues.
• Why React?
  • In my opinion it's the most complicated to set up. You can swap React for Vue in the project simply by replacing webpack plugins and loaders. You can't do it another way around. And Angular 2 has it's own ecosystem. You can easily enable TypeScript on this project, but I didn't want to make it a default.
• Koa1/Express/Node.js < 7.6?
  • No.
• Why local modules?
  • To avoid ../../../relative.hell.js and ensure consistent loading of each module (in index.js, you can ensure some logic always runs before module is loaded). It's similar to Java packages in a way.
• Why is gulp disabled?
  • Ran into problems running it together with webpack (or webpack through gulp to be more precise). Didn't see enough benefit to it, so left it alone. I think gulp is a good way to prepare and optimize assets before deployment to production, but Webpack is better for development.

TODO

• Some kind of visual diagram for how the project is organized when I have time.
• Some actual boilerplate functionality for React/Redux
