Matrix chat: [#mitra:halogen.city](https://matrix.to/#/#mitra:halogen.city)

## Requirements

- Rust 1.54+ (when building from source)
- PostgreSQL 12+
- IPFS node (optional, see [guide](./docs/ipfs.md))
- Ethereum node (optional)

## Installation

### Building from source

Run:

```
cargo build --release --features production
```

This command will produce two binaries in `target/release` directory, `mitra` and `mitractl`.

Create the database and the configuration file (see [example](./config.yaml.example)). Default config file path is `/etc/mitra/config.yaml`, but it can be changed using `CONFIG_PATH` environment variable.

Start Mitra:

```
./mitra
```

An HTTP server will be needed to handle HTTPS requests and serve the frontend. See the example of [nginx configuration file](./contrib/mitra.nginx).

Building instructions for `mitra-web` frontend can be found at https://codeberg.org/silverpill/mitra-web#project-setup.

To run Mitra as a systemd service, check out the [systemd unit file example](./contrib/mitra.service).

## Development

### Create database

```
docker-compose up
```

Test connection:

```
psql -h localhost -p 55432 -U mitra mitra
```

### Run web service

Create config file, adjust settings if needed:

```
cp config.yaml.example config.yaml
```

Compile and run service:

```
cargo run
```

### Run CLI

```
cargo run --bin mitractl
```

### Run linter

```
cargo clippy
```

### Run tests

```
cargo test
```

### Build for production

See [FEDERATION.md](./FEDERATION.md)

## Client API

### Mastodon API

Most methods are similar to Mastodon API, but Mitra is not fully compatible.
