Development Guide
Before contributing, make yourself familiar with our contribution guidelines and the technical documentation for this project.
Before getting started, you'll want to install:
- Rust toolchain (rustup recommended)
- Docker
- Git
- mold (optional, faster compilation)
A default.nix is available for Nix users!
Just run nix-shell and continue.
As a heads-up, the development environment uses the following ports:
| Service |
Port |
| MongoDB |
14017 |
| Redis |
14079 |
| MinIO |
14009 |
| Maildev |
14025
14080 |
| Revolt Web App |
14701 |
crates/delta |
14702 |
crates/bonfire |
14703 |
crates/services/autumn |
14704 |
crates/services/january |
14705 |
Now you can clone and build the project:
git clone https://github.com/revoltchat/backend revolt-backend
cd revolt-backend
cargo build
A default configuration Revolt.toml is present in this project that is suited for development.
If you'd like to change anything, create a Revolt.overrides.toml file and specify relevant variables.
[!TIP]
Use Sentry to catch unexpected service errors:
# Revolt.overrides.toml
[sentry]
api = "https://abc@your.sentry/1"
events = "https://abc@your.sentry/1"
files = "https://abc@your.sentry/1"
proxy = "https://abc@your.sentry/1"
Then continue:
# start other necessary services
docker compose up -d
# run the API server
cargo run --bin revolt-delta
# run the events server
cargo run --bin revolt-bonfire
# run the file server
cargo run --bin revolt-autumn
# run th proxy server
cargo run --bin revolt-january
# hint:
# mold -run <cargo build, cargo run, etc...>
You can start a web client by doing the following:
# if you do not have yarn yet and have a modern Node.js:
corepack enable
# clone the web client and run it:
git clone --recursive https://github.com/revoltchat/revite
cd revite
yarn
yarn build:deps
echo "VITE_API_URL=http://local.revolt.chat:14702" > .env.local
yarn dev --port 14701
Then go to http://local.revolt.chat:14701 to create an account/login.
When signing up, go to http://localhost:14080 to find confirmation/password reset emails.
Deployment Guide
Cutting new crate releases
Begin by bumping crate versions:
just patch # 0.0.X
just minor # 0.X.0
just major # X.0.0
Then commit the changes to package files.
Proceed to publish all the new crates:
just publish
Cutting new binary releases
Tag and push a new release by running:
just release
If you have bumped the crate versions, proceed to GitHub releases to create a changelog.
Testing
First, start the required services:
docker compose -f docker-compose.db.yml up -d
Now run tests for whichever database:
TEST_DB=REFERENCE cargo nextest run
TEST_DB=MONGODB cargo nextest run
