Bolt

Super-powered JavaScript project management

Introduction

Find it difficult to manage lots of components, libraries, or services? Juggling lots of Node packages in lots of different repositories? What if there was a better way?

Diagram: One package per project

Most JavaScript projects have 1 package per project (repo). So when you have lots of packages, you have to do a lot of work to manage them all.

  • You need to install every single package one by one.
  • If you make changes to one package and want to test them in another, you need to manually link them together and run tests separately.
  • Managing dependencies and keeping everything up to date can be overwhelming, and you can easily fall really far behind.

Instead of all that, what if you put all of your packages together?

Diagram: Project with many packages

This is the idea behind "workspaces".

What are workspaces?

Within a project, a workspace is just a directory with its own package.json.

project
├── package.json
├── workspace-one
│   ├── package.json
│   └── index.js
└── workspace-two
    ├── package.json
    └── index.js

Put another way, workspaces are just like any other package, except they are nested within a larger project. Each workspace can have its own dependencies with its own code and scripts.

Using Bolt, you can install the dependencies for all of these packages at once (and you can do it really really fast).

But here's where it gets really cool: When you specify a dependency from one workspace to another. It will get linked to the actual source. This way, when you go to test your code. All your changes get tested together.

What is Bolt?

Bolt implements the idea of workspaces on top of Yarn. In fact, the Bolt CLI is largely a drop-in replacement of the Yarn CLI. You can use it on any project already using Yarn.

But Bolt (will soon) do lots of other stuff. Instead of wasting tons of time setting up a whole bunch of build tools for running your tests, or compiling your code, what if your package manager just did all that for you? Then when you want to do something differently, all you need to do is override a script.

Well that's what Bolt will do for you (once we get around to implementing it).

Long term, many of the features in Bolt will hopefully prove to be useful and other package managers like Yarn and npm will adopt them.

Installation

First be sure that you have Node/npm and Yarn installed. Then run the following command:

yarn global add bolt

Thanks to Cam Pedersen (@ecto) for the "bolt" package name on npm
