Firebase Local Emulator

[n0rthk1n9]

What it Does

• Closes Setup the Firebase Local Emulator  #14
• It makes the app testable against a local emulated Firebase Auth and Firebase Firestore instance

How I Tested

• Make sure Node v 8.0 or higher is installed
• Make sure Openjdk v 11 or higher is installed (If you installed it via brew, don't forget to add the executable to $PATH, brew will output it as a handy command to execute for you)
• Make sure firebase-cli is installed (npm install -g firebase-tools)
• Make sure you ran firebase login and authenticated successfully
• Go to backend/Basic-Car-Maintenance and run firebase emulators:start
• Now every request from the app should go against the emulator
• In the emulator UI at http://127.0.0.1:4000/ you can check if the data you added in the app is added in the emulated Firestore

Notes

• Anything else that should be noted about how you implemented this feature?

Great work!! I haven't tested this because I haven't downloaded everything

• Make sure Node v 8.0 or higher is installed
• Make sure Openjdk v 11 or higher is installed (If you installed it via brew, don't forget to add the executable to $PATH, brew will output it as a handy command to execute for you)
• Make sure firebase-cli is installed (npm install -g firebase-tools)

Can you note the best way to download these? (Preferably with Homebrew) Also I have a few questions, you can comment directly in that thread

When would this flag need to be enabled vs disabled? Only when wanting to use the emulator? Otherwise it would be unchecked, which would default to using the real project?

[n0rthk1n9]

Yes exactly

[mikaelacaron]

Why use UseDefaults, as opposed to the command line argument?

[n0rthk1n9]

Honestly I don't have a better answer to that question than "Because Peter recommended it doing it like that in his article" But I guess it could also be done via command line arguments, if you prefer that :)

The best way to install all the requirements is indeed via homebrew:

1. brew install nvm (Installs node version manager, so you don't need to update the system node version)
2. nvm install stable and nvm use stable to download and set the last stable node version
3. brew install openjdk to install openjdk. Add the executable to the $PATH via .zshrc or .bashrc file as prompted after installation
4. npm install -g firebase-tools

With that all prerequisites should be installed. Let me know if anything doesn't work
