Running the app

Prerequisites:

If running tryn-react with the backend running locally:

• Have tryn-api running and ensure that it's in the same parent directory as this repo.
• go to envEndpoints.json and set the USE_PROD_ENDPOINT flag to false.

If running tryn-react using the production API (recommended - do this unless you're working on the backend):

• Clone tryn-api to the same parent directory as this repo.
• Checkout the prod branch in tryn-api.

Once you're ready:

1. Ensure you have the config.json file in the src directory. You can get this from the shared files section of our Slack channel.
2. Run yarn.
3. OPTIONAL: Install Watchman via brew install watchman.
4. Run yarn run relay or (if you installed Watchman) yarn run relay --watch
5. Run yarn start.
