Welcome to Rusve!

What is Rusve?

It is a attempt to find the best way to build fast and scalable web applications, while not beeing afraid of new technologies. And I think we are getting there.

Feel free to ask questions and throw new ideas! Any contribution is also welcome, especially some ux/ui redesigns :)

Currently working on...

• Markdown
• Telemetry
• Make it more resistanc to no js
• Any other feature You will request :)

Features

• Backend
  • Microservices - Splitted into smaller parts, very easy to scale, and allows using any combination of languages and databases. Project have ready to use both Go and Rust services.
  • Go - Very easy to work with while still having an amazing performance. Out of the box support for gRPC. Recommended to start with.
  • Rust - For more complex services use Rust, hard but amazing language. Almost impossible to write code that will not start.
  • gRPC - Connection between services using gRPC, which is very fast and gives an option for bi-directional streaming. For Rust using great Tonic create, with first class support of async/await.
  • Typesafety - Thanks to protobuf, amazing typesafety across the whole project, no matter the language (not only for TS, hi tRPC).
  • Sql Pools and Transactions - Using the best practice for the best performance and error handling.
  • Dockerized - Every service is dockerized. Local build ready with one command.
• Frontend
  • SvelteKit - Once You try it, it's hard to go back to any other framework.
  • Typescript - Fully written in typescript with the strict rules enforced. No any or unknown in code.
  • Form actions - Forms are handled by server, which force You to seperate view and logic. This is a great pattern and makes the logic unaccesible by the browser.
  • Zod validation - Every data if validated. Errors are returned and used by client to view them on forms.
  • Streaming - Important data is loaded and rendered first, after that all the rest are returned as promises and rendered when they resolve.
  • PWA with service workers - Turn off the internet and check how resiliant the app is.
  • Firebase SSR Authentication - Battle-tested OAuth, Magic Link, Phone Number. And by doint it on Svelte server, it's much more secure.
  • TailwindCSS - Used for styling, no other UI library needed.
  • Minimal external libraries - With Svelte animation and stores builing custom components is very easy. Checkout Toast, Drawer, Modal, Dropdown and see for yourself.
• Deployment
  • Github Action - Ready to use github actions for deployment, each service is linted and checked. Possible to deploy all services or a single one.
  • Google Cloud Platform - Easy to deploy, easy to scale, easy to maintain, and still cheap.
  • Google Cloud Run - Thanks to dockerized application, it's very easy to deploy. Scaling done automatically, can set the min. instances to 1 to reduce cold start.
  • Google Cloud Storage - Working files upload, download and delete.
  • Google PubSub - Asynchronus data sending.
• Additional features
  • Stripe - Fully working subscription flow.
  • HeadlessCMS - Headless cms via Directus.
  • WYSIWYG - Wyswig text editor thanks to TipTap.

Github action deployment

Release all

Release single

Aria and PWA with offline service workers

Dev deployment

1. Client setup

cp client/.env.example client/.env
npm i --prefix client

2. Run proto generation Be sure to have protoc installed.

sh proto.sh

2. Fill in missing firebase secrets in client/.env

• STRIPE_API_KEY
• PUBLIC_API_KEY
• PUBLIC_AUTH_DOMAIN
• SERVICE_ACCOUNT

Getting the SERVICE_ACCOUNT key is a bit tricky.

3. Start docker:

docker-compose up --build

4. Access:

Application - http://localhost:3000
CMS - http://localhost:8055 | Login: [email protected] | Password: d1r3ctu5

Production deployment

1. Go through each deploy-***.yml and change env acording to Your project.

2. Add secrets to github

• GCP_CREDENTIALS
• DB_PASS
• STRIPE_API_KEY
• SENDGRID_API_KEY
• PUBLIC_API_KEY
• PUBLIC_AUTH_DOMAIN
• SERVICE_ACCOUNT

3. Add proper IAM permissions

Bonus: Three ways to shows notes. Not implemented in application, but all the code is there to try it.

This project shows how flexible the gRPC + SvelteKit setup is, using the newest SvelteKit streamed feature. There are three ways to display notes:

1. svelte server calls notes service -> notes service selects all notes -> for each note it calls users service for user -> the note with the user is returned as stream
2. svelte server calls notes service -> notes service selects all notes and return them -> for each note svelte server calls users service for user -> not waiting for users to resolve, he dispaly the notes, and after that await users as streamed data
3. svelte server calls notes service -> notes service selects all notes and return them -> for each note svelte server add userId to set -> then, in one request he calls users service for all users -> not waiting for users to resolve, he displays notes and after that await users as streamed data
