This is the web app for the Budget Zen app, built with Deno and deployed using docker compose.

This is v3, which is end-to-end encrypted with open Web Standards, and works via web on any device (it's a PWA - Progressive Web App).

It's not compatible with Budget Zen v2 (end-to-end encrypted via Userbase) which you can still get locally from this commit, nor v1 (not end-to-end encrypted), which you can still get locally from this commit. You can still export and import the data as the JSON format is the same across all 3 versions (unencrypted).

NOTE: If your Android launcher doesn't show PWAs as an app, I've got a solution for you: a simple webview app.

Or check the Development section below.

NOTE: You don't need to have emails (Brevo) and subscriptions (Stripe) setup to have the app work. Those are only used for allowing others to automatically manage their account. You can simply make any user.status = 'active' and user.subscription.expires_at = new Date('2100-01-01') to "never" expire, in the database, directly.

This right here is vanilla TypeScript and JavaScript using Web Standards. It's very easy to update and maintain.

It's meant to have no unnecessary dependencies, packagers, or bundlers. Just vanilla, simple stuff.

This was tested with Deno's version stated in the .dvmrc file, though other versions may work.

For the PostgreSQL dependency (used when running locally, self-hosted, or in CI), you should have Docker and docker compose installed.

If you want to run the app locally with SSL (Web Crypto standards require https except for Chrome), you can use Caddy (there's a Caddyfile that proxies https://localhost to the Deno app).

Don't forget to set up your .env file based on .env.sample.

$ docker compose up # (optional) runs docker with postgres, locally
$ sudo caddy run # (optional) runs an https proxy for the deno app
$ make migrate-db # runs any missing database migrations
$ make start # runs the app
$ make format # formats the code
$ make test # runs tests

$ make exec-db # runs psql inside the postgres container, useful for running direct development queries like `DROP DATABASE "budgetzen"; CREATE DATABASE "budgetzen";`
