You will need

Before installing your development environment you’ll need to install each of these prerequisites:

Clone the Git repo

git clone https://github.com/hypothesis/h.git

This will download the code into an h directory in your current working directory. You need to be in the h directory from the remainder of the installation process:

cd h

Run the services with Docker Compose

Start the services that h requires using Docker Compose:

make services

Start the development server

make dev

The first time you run make dev it might take a while to start because it’ll need to install the application dependencies and build the client assets.

This will start the server on port 5000 (http://localhost:5000), reload the application whenever changes are made to the source code, and restart it should it crash for some reason.

That’s it! You’ve finished setting up your h development environment. Run make help to see all the commands that’re available for running the tests, linting, code formatting, Python and SQL shells, etc.
