🚩🚩🚩ALERT! ALERT! ALERT!🚩🚩🚩

develop is now the default branch to work against for all development (edited)

Tien or Roland will merge develop into master periodically when it’s time to update the demo!

This project meets on Monday at the westside hacknight. We are working with a program of the City of LA's Attorney's Office which supports the Criminal Record Clearing Project by administering the Los Angeles County Homeless Court Program. HEART (Homeless Engagement and Response Team) deploys its staff to homeless connect days in the community where adults who are experiencing homelessness or are at risk of experiencing homelessness may enroll in the program. The program helps participants resolve eligible traffic and pedestrian infraction citations by engaging in services instead of paying fines and fees they cannot afford. HEART files a motion with the Los Angeles Superior Court, requesting a dismissal and/or suspension of fines, and a recall of associated warrants.

Hack for LA has been working with the program's staff to design and build a better processing system, helping to streamline in-person client intake, data processing and the filing of motions.

Find us on the Hack for LA Slack on the channel #heart, or join us at one of our meetings, every Monday night in Santa Monica.

This serves both the backend api and frontend pages for the processing system and will be used to review and process participant info. Below is a brief overview of the tech involved in this project.

• Express is serving the api and an index page
• Jest runs the tests
• Linting is setup with the airbnb style guide
• CI is setup with Travis-CI
• Some simple routes exist for a notes table
• Postgres is seeded with participant table and a citations table

• Latest version of Docker is required must be installed on your computer.
• Node and NPM does not have to be installed but it is highly recommended.

1. cd into main-app
2. run docker-compose build
3. run docker-compose up once the obove command is finished running. This will bring up heart_node, heart_postgres, and heart_pgadmin containers and start the application.
4. Go to localhost:3000 to access main-app using user: demo password: pwd123
5. Go to localhost:8080 to access pgadmin using user: [email protected] password: pgadmin.

See "How to browse postgres using pgadmin" section below if you wish to see the db structure.

1. ensure your containers are up with docker-compose up
2. run docker exec -it heart_node npm test (This will work for now but it is slow so we are exploring other options)

This project provides a dockerized node app, postgres and pgadmin. A local database is not required to start working on this project.

To use what we've provided, you'll need the latest version of NodeJS, Docker and Docker Compose (comes with a standard Docker Desktop installation for Mac and Windows.)

\design                 // contains design files
\main-app               // contains the full application
  \api                  // contains all the backend code
  \client               // contains the front-end code
  docker-compose.yml
README.md               // you are reading it

User: demo Password: pwd123

User: [email protected] Password: pgadmin

Use your favorite Command Line Interface (e.g. bash or powershell) and change into the main-app directory.

Enter the commands:

 docker-compose build
 docker-compose up (after above command finishes)

This downloads and builds the base Docker images (if needed), and starts all services.

node can now be accessed from http://localhost:3000. It serves the main-app.

pgadmin can now be accessed from http://localhost:8080. It's a GUI for browsing postgres.

postgres service exposes the standard PostgreSQL port 5432. It serves the main-app database.

[SERVICE] is node, postgres or pgadmin

If one service or another is already started:

docker-compose up [SERVICE]

To stop the service(s):

docker-compose stop [SERVICE]

The default port is 5432

The default postgres credentials are:

POSTGRES_USER=postgres
POSTGRES_PASSWORD=postgres

Use the PostgreSQL connection URI:

postgresql://<user>:<password>@<host>:<port>/<database>

With our defaults:

postgresql://postgres:postgres@localhost:5432/heart

[email protected]
PGADMIN_DEFAULT_PASSWORD=pgadmin

Go to localhost:8080 and login.

Then trom the top navbar Object > Create > Server.

On the General tab, fill in whatever Name you want.

On the Connection tab, fill in:

• Hostname/address: postgres (the name of the local service, as noted in docker-compose.yml

• Port: 5432 (default)

• Maintenance database: postgres (default)

• Username: postgres (from POSTGRES_USER)

• Password: postgres (from POSTGRES_PASSWORD)

The rest of the fields can be left blank. Click Save to connect.

In the future, the server you saved can be used again

If the services are started and stopped as outlined above, changes made within the postgres database server (e.g. creating tables, inserting data) and the pgadmin client (e.g. server connections, preferences) will persist between restarts.

An alternative command can stop and completely remove all services and any associated local storage. *This is destructive*:

docker-compose down [SERVICE]
