Installation

Prerequisites

Setup for Docker

The Docker setup will create a fully functional development environment preconfigured for Gravity PDF.

  1. Clone the repository using git clone https://github.com/GravityPDF/gravity-pdf/ from the terminal
  2. Copy and rename .env.example to .env, then replace 00000000000000000000000000000000 with a valid Gravity Forms license key
  3. Run yarn && yarn build:production
  4. Start Docker and then run yarn env:install to setup the local development environment
  5. Access a local development site at http://localhost:8888 with the login admin and password.

If you shut down Docker and want to fire up the environment later, use yarn wp-env start. You can reset the database back to its original state with yarn wp-env clean all. When all else fails, delete everything and start again with yarn wp-env destroy.

See the WordPress Developer Handbook for more details about managing the docker environment.

The default version that will be configured is PHP8.0. If you want to change this you can adjust the phpVersion value in the .wp-env.json file and then stop and start the environment with yarn wp-env start.
