## Minimum Supported Rust Version
|
|
|
|
Rust 1.86.0 or higher.
|
|
|
|
> [!CAUTION]
|
|
> The events server has a significant performance regression between Rust 1.77.2 and 1.78.0 onwards, see [issue #341](https://github.com/revoltchat/backend/issues/341). This is currently solved by build time options but we are looking for a proper fix.
|
|
|
|
## Development Guide
|
|
|
|
Before contributing, make yourself familiar with [our contribution guidelines](https://developers.revolt.chat/contrib.html) and the [technical documentation for this project](https://revoltchat.github.io/backend/).
|
|
|
|
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 | 27017 |
|
|
| Redis | 6379 |
|
|
| MinIO | 14009 |
|
|
| Maildev | 14025<br>14080 |
|
|
| Revolt Web App | 14701 |
|
|
| RabbitMQ | 5672<br>15672 |
|
|
| `crates/delta` | 14702 |
|
|
| `crates/bonfire` | 14703 |
|
|
| `crates/services/autumn` | 14704 |
|
|
| `crates/services/january` | 14705 |
|
|
| `crates/services/gifbox` | 14706 |
|
|
|
|
Now you can clone and build the project:
|
|
|
|
```bash
|
|
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:
|
|
>
|
|
> ```toml
|
|
> # 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"
|
|
> ```
|
|
|
|
> [!TIP]
|
|
> If you have port conflicts on common services, you can try the following:
|
|
>
|
|
> ```yaml
|
|
> # compose.override.yml
|
|
> services:
|
|
> redis:
|
|
> ports: !override
|
|
> - "14079:6379"
|
|
>
|
|
> database:
|
|
> ports: !override
|
|
> - "14017:27017"
|
|
>
|
|
> rabbit:
|
|
> ports: !override
|
|
> - "14072:5672"
|
|
> - "14672:15672"
|
|
> ```
|
|
>
|
|
> And corresponding Revolt configuration:
|
|
>
|
|
> ```toml
|
|
> # Revolt.overrides.toml
|
|
> # and Revolt.test-overrides.toml
|
|
> [database]
|
|
> mongodb = "mongodb://127.0.0.1:14017"
|
|
> redis = "redis://127.0.0.1:14079/"
|
|
>
|
|
> [rabbit]
|
|
> port = 14072
|
|
> ```
|
|
|
|
Then continue:
|
|
|
|
```bash
|
|
# start other necessary services
|
|
docker compose up -d
|
|
|
|
# run everything together
|
|
./scripts/start.sh
|
|
# .. or individually
|
|
# 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 the proxy server
|
|
cargo run --bin revolt-january
|
|
# run the tenor proxy
|
|
cargo run --bin revolt-gifbox
|
|
# run the push daemon (not usually needed in regular development)
|
|
cargo run --bin revolt-pushd
|
|
|
|
# hint:
|
|
# mold -run <cargo build, cargo run, etc...>
|
|
# mold -run ./scripts/start.sh
|
|
```
|
|
|
|
You can start a web client by doing the following:
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
just publish
|
|
```
|
|
|
|
### Cutting new binary releases
|
|
|
|
Tag and push a new release by running:
|
|
|
|
```bash
|
|
just release
|
|
```
|
|
|
|
If you have bumped the crate versions, proceed to [GitHub releases](https://github.com/revoltchat/backend/releases/new) to create a changelog.
|
|
|
|
## Testing
|
|
|
|
First, start the required services:
|
|
|
|
```sh
|
|
docker compose -f docker-compose.db.yml up -d
|
|
```
|
|
|
|
Now run tests for whichever database:
|
|
|
|
```sh
|
|
TEST_DB=REFERENCE cargo nextest run
|
|
TEST_DB=MONGODB cargo nextest run
|
|
```
