TERN is a stack for web development consisting of Tigris as a database (and search), Express.js for the web server, React for the client, and Node.js for the server runtime.

This codebase is a fork of the MongoDB MERN stack codebase.

• A Tigris Cloud account or a self-hosted Tigris instance
• Node.js LTS or above

Create a tern/server/config.env from the tern/server/config.env.example:

cp tern/server/config.env.example tern/server/config.env

Create a project in Tigris (e.g. via the Tigris Cloud Console) and populate the configuration values in the config.env file:

TIGRIS_CLIENT_ID={TIGRIS_CLIENT_ID}
TIGRIS_CLIENT_SECRET={TIGRIS_CLIENT_SECRET}
TIGRIS_PROJECT=mern-to-tern
TIGRIS_URI=api.preview.tigrisdata.cloud
TIGRIS_DB_BRANCH=main
PORT=5000

Start the server:

cd tern/server
npm install
npm start

Start the client:

cd tern/client
npm install
npm start

The MERN code base came with some tests that don't appear to run by default when running npm test. However, you can manually run the existing two tests by starting the client and server (as above) and then running:

node_modules/.bin/cypress run cypress/integration/endToEnd.spec.js
