Gatsby Error Testing

Gatsby has structured errors with specific IDs. With this suite you can test certain error messages directly with a test project, e.g. to see if the error message helps with solving the problem.

Usage (Locally)

Ensure that you have the latest LTS version of Node installed. Install yarn.

Clone the repository and run in your terminal:

yarn install

After a successful installation you can use the CLI:

yarn begin

Choose one of the testing sites. Also open this repository in your favorite code editor and go to the sites directory. Each folder in there has the name of the error ID you chosen after running yarn begin. Go into this folder and you'll have a normal Gatsby project. You could e.g. directly open this folder in your editor.

Usage (Codesandbox)

Note: This requires an account on CodeSandbox

Click on the Edit on CodeSandbox button, press Fork and let CodeSandbox do its thing. On the right side there is the Browser window and below that the Terminal, Console, Problems tabs. Click on Terminal and then on the + sign. You now should have two tabs (yarn start and /bin/bash). The /bin/bash one should be automatically selected and a new terminal window appeared. Type yarn begin + Enter.

Now you're in the same state as locally — choose the correct folder inside sites and try to solve your error :)

Adding a new error

Create a new project based on the hello-world starter or copy/paste one of the existing projects inside ./sites to a new folder inside ./sites with the name being an ID from the errormap. Make sure to run a yarn install after adding/copying a site.

You'll also need to add a new option to the CLI inside ./cli/index.js with the name as the ID, message as the longer description.
