Completely rewritten and revitalized by Connor Roizman, Eli Schiff, and Jeff Putlock.

See our User's Manual.

1. Clone the repository via git clone https://github.com/Bram-Hub/Willow.git.

2. Install nodejs version 14 and install project dependencies via npm ci from the project root directory.

3. Install postgresql and start the service. Set up the Willow database via the following steps:

   1. Open a Postgres interactive shell as the postgres user: sudo -iu postgres; psql -U postgres

   2. Set up the Postgres user willow_user and the willow database:

      CREATE ROLE willow_user WITH LOGIN PASSWORD 'your_password_here';
      CREATE DATABASE willow WITH OWNER willow_user;
      \connect willow;
      CREATE EXTENSION pgcrypto;
      

   3. (OPTIONAL) Edit /etc/postgresql/VERSION_NUMBER/main/pg_hba.conf to allow users other than postgres to log in to the willow_user role in postgres.

   4. Exit the postgres shell and navigate to the root directory of the Willow repository. Set up the new database as willow_user using psql -U willow_user -W willow < setup.sql

4. Create an env file cp .env.template .env and configure the following options

   Variable	Description
   NODE_ENV	The environment in which this application is being run. The possible values are development and production
   HTTPS	If the program is being run on an https server
   PORT	The port to launch the program on
   BASE_URL	The base url for example "http://localhost:8080"
   PGHOST	The PostgreSQL host to connect to
   PGUSER	The PostgreSQL user to log in as
   PGDATABASE	The PostgreSQL database to use
   PGPASSWORD	The password for the account specified by PGUSER
   PGPORT	The port that the database is hosted on

5. Create a config file cp config.yml.template config.yml to configure your list of system administrators.

6. (OPTIONAL) Set up the unit testing framework with npx ts-jest config:init

7. Launch the application using npm run <command> with one of the commands in the table below.

   Command	Use
   debug	Recommended for development. Uses nodemon to recompile the code when changes are made.
   test	Runs the unit test suite (requires setup in step 6)
   dev	Runs the program once. Must be restarted when changes are made
   build	Builds the website in production mode
   start	Runs the built program
