About

This is the website that is hosted at https://http.cat.

The code for the older version hosted at the heroku platform is at the http-status-cats-api repo.

This version does not need any server side code. The API behavior is provided by a Nginx server config.

On v2.0.0 the website was built with React and pre-rendered with react-snap.

As of v3.0.0 it's built with Next.js 13.

Development

npm run dev

Runs the tests.

npm run build

Creates a build of the project.

Adding a new image

Currently not all HTTP status codes are covered. You are welcome to create an issue or PR to cover them.

We've prepared some templates to make this process easier.

You can clone it, replace the information with the new one and export as a JPG image.

Then, upload it to both public/images and public/images-original folders and update the statuses.js file.

Finally you need to add a markdown file in /content/<status-code>.md with a description of the status code and links to official documentation. Please follow the format of already existing files. Also, copy this file over to /content/ca and ask Copilot, ChatGPT or Google, etc to translate the content to Catalan.
