Build rules

Frontend:

  1. Install Angular denpendencies

    • Install Node.js & npm

    • Check Node.js version and npm version by entering

      node -v

      npm -v

    Note: If you met compatbility issue, please consider install Node to v18.12.0 and Angular Cli to 14.2.13

  2. Install Angular-cli by running npm install -g @angular/cli

    • Check version by running

      ng version

  3. go to fronend folder, and run following commands to build the frontend

    npm install

    ng serve

Backend

Install pkgs

Make sure you have python3.7+, pip3, python3-venv installed on your machine

  1. To check pip3 version, run pip3 -V, or run sudo apt-get install python3-pip to install it on your machine

  2. Run sudo apt-get install python3-venv to install python3-venv.

Build and run the backend

  1. Make sure you have a python virtual environment on your local machine and install all dependencies in the virtual environment.
    • Create a virtual environment by running python3 -m venv venv or virtualenv venv. (Recommend to put the environment folder at project's root folder)
    • Activate the environment by running source venv/bin/activate
    • pip3 install wheel
    • install packages in the environment by running pip3 install 'package-name'
  2. go to the backend folder, run the following commands to build the backend server Make sure that you are in a virtual environment before you run this command
    • pip3 install -r requirements.txt (Only need to run this command at the first time)
    • ./build.sh
  3. Leave the virtual environment
    • deactivate

Browser

After finishing set up the frontend and backend, open the browser(recommend chrome) and visit "http://localhost:4200/", you should be able to see the website connected with the backend.

Dev Workflow

One time actions:

  1. Fork the repo
  2. Clone the forked repo locally
    • git clone git@github.com:/power-data-graphing-intern-2020.git
  3. Add upstream remote
    • git remote add upstream git@github.com:googleinterns/power-data-graphing-intern-2020.git
    • Run “git remote -v”, the origin is the fork repo, upstream is the actual repo.
      • origin git@github.com:yaomeng-google/power-data-graphing-intern-2020.git (fetch)
      • origin git@github.com:yaomeng-google/power-data-graphing-intern-2020.git (push)
      • upstream git@github.com:googleinterns/power-data-graphing-intern-2020.git (fetch)
      • upstream git@github.com:googleinterns/power-data-graphing-intern-2020.git (push)

When I am going to work on a new feature:

  1. sync my fork's main branch to upstream's main branch
    • git checkout main; git fetch upstream; git rebase upstream/main
  2. create a new branch from main
    • git checkout -b cool_feature
  3. do my coding
  4. add and commit my changes
    • git add *; git commit -m "New feature"
  5. push my branch to my fork
    • git push origin cool_feature
  6. pull-request my branch from my fork to the upstream repo
    • done in the git hub UI
  7. deal with any code review code changes by making commits and updating the branch in my fork (this updates the open pull-request)
    • git add *; git commit -m "Fixes form review"; git push origin cool_feature
  8. merge the branch into the upstream repo's main branch
    • done in github ui
  9. delete my development branch
    • normally done in github ui

Deploy the project to Google Cloud Platform

  1. Download gcloud SDK by following this link
  2. Initialze gcloud project by running gcloud init, auenticate with your google acount, and select the option of setting up a new project by entering a new project id, for tank-big-data-plotting, the project id is: google.com:tank-big-data-plotting-285623
  3. Go to the /frontend folder, build the prod version of the frontend by entering ng build --prod. Then go to the generated /dist folder, run gcloud app deploy. Make sure if your gcloud project setup is correctly, and the target service is set as default
  4. Go to the /backend folder, run gcloud app deploy, and make sure the target service is set as api.
  5. Go to the gcp console and make sure the latest frontend and backend have been uploaded.

Note: If you meet into permission issue, please send requests to longzhao@google.com to ask for GCP project permission.
