Quick Start

How to contribute

Filing an issue

If you want your issue to be resolved quickly, please include in your issue:

  • Gatsby version, node.js version, OS version
  • The contents of your gatsby-config.js and package.json as well as your gatsby-node.js, gatsby-browser.js gatsby-ssr.js files depending on changes you’ve made there.


You can install the latest master version of Gatsby by following these steps:

  • Clone the repo, navigate to its directory.
  • Install dependencies using npm install in the root of the repo.

The usual contributing steps are:

  • Fork the official repository.
  • Clone your fork: git clone<your-username>/gatsby.git
  • Install lerna, and gatsby-dev-cli globaly: npm install -g lerna gatsby-dev-cli@canary
  • Checkout to the 1.0 branch: git checkout 1.0
  • Install dependencies: npm install && lerna bootstrap
  • Make sure tests are passing for you: npm test
  • Create a topic branch: git checkout -b topics/new-feature-name
  • Run npm run watch to do an initial build of all packages and watch for changes to packages’ source code and compile changes on the fly as you work.
  • For each of your Gatsby test sites, run the gatsby-dev command there to copy the built files from your cloned copy of Gatsby. For more detailed instructions see the gatsby-dev-cli README
  • Add tests and code for your changes.
  • Once you’re done, make sure all tests still pass: npm test
  • Commit and push to your fork.
  • Create an pull request from your branch.

Development tools

Redux devtools

Gatsby uses Redux for managing state during development and building. It’s often helpful to see the flow of actions and builtup state for a site you’re working on or if adding new functionality to core. We leverage and to give you use the Redux devtools extension for debugging Gatsby.

To use this, first install redux-devtools-extension in your browser. Then in your Gatsby repo, run npm run remotedev. Then in your site directory run REDUX_DEVTOOLS=true gatsby develop. Depending on your operating system and shell, you may need to modify how you set the REDUX_DEVTOOLS environment variable.

At this point, your site will be sending Redux actions and state to the remote server.

To connect to this, you need to setup the devtools extension to talk to the remote server.

First open the remote devtools.

Then click settings along the bottom menu and set the host and port.

After this, the devtools extension should connect to the remote server and you’ll see actions start showing up.

Warning!! Lots of buginess. While having this available is extreamly helpful, this setup is very buggy and fragile. There is a memory leak in the extension that’s triggered it seems every time you restart the Gatsby development server. Also the extension often, for no apparent reason, just won’t show any actions from the remote server. It’ll also often freeze up. The best solution seems to just be turning everything off and on again. Fixing up these tools would be very helpful for us and many others using these tools if someone wants to take this on!
