ATD Mobile Signals Work Orders

This repo hosts code for our a mobile first, reactive UI application built for Signal Technicians out in the field working from Android tablets. This project uses a React.js custom client interface and connects with Knack databases via their REST API.

This project was bootstrapped with Create React App.


production branch is our deployed production code. It deploys via Netlify to It consumes data from the production Data Tracker labeled as "Austin Transportation Data Tracker | Production". We should be very cautious changing any data in the production app environment.

master branch is our staging branch. It deploys via Netlify to It consumes data from the test instance of Data Trackers labeled as "13 AUG 2019 | TEST - Austin Transportation Data Tracker".

Any feature development should be done in feature branches branched from the master/staging branch. They should be tested against our test Knack database. Once merged to staging, we can then create a pull request comparing base:production to compare:master for final review before pushing to production.

Updating Knack App IDs

Knack App IDs are stored in two places:

  1. As environment variables in ./netlify.toml
  2. As reference variables in ./src/constants/api.js

If the production or test Knack database changes, you'll need to update the IDs in both places.
