Development Guide

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.

Now you can clone and build the project:

git clone https://github.com/revoltchat/backend revolt-backend
cd revolt-backend
cargo build

If you want to run the API and event servers:

# create environment file (will be deprecated in future)
cp .env.example .env

# (optionally) copy the default configuration file
cp crates/core/config/Revolt.toml Revolt.toml
# configure as necessary...

You may want to copy the following configuration:

# Revolt.toml
[database]
mongodb = "mongodb://localhost"
redis = "redis://localhost"

[hosts]
app = "http://local.revolt.chat"
api = "http://local.revolt.chat:8000"
events = "ws://local.revolt.chat:9000"
autumn = "http://local.revolt.chat:3000"
january = "http://local.revolt.chat:7000"
voso_legacy = ""
voso_legacy_ws = ""

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

# 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
yarn dev --port 3001

Then go to https://local.revolt.chat:3001
