## Requirements

### Standalone setup
- PostgreSQL 15.0
- Redis
- Node v18
- Typescript

### Docker setups
- Node v18
- Docker v20.10
- Docker compose v2.10

## Full Guide

- [Set up a Nostr relay in under 5 minutes](https://andreneves.xyz/p/set-up-a-nostr-relay-server-in-under) by [André Neves](https://twitter.com/andreneves) (CTO & Co-Founder At [ZEBEDEE](https://zebedee.io/))

## Quick Start (Docker Compose)

Install Docker following the [official guide](https://docs.docker.com/engine/install/).
You may have to uninstall Docker if you installed it using a different guide.

Clone repository and enter directory:
  ```
  git clone git@github.com:Cameri/nostr-ts-relay.git
  cd nostr-ts-relay
  ```

Start:
  ```
  ./scripts/start
  ```
  or
  ```
  ./scripts/start_with_tor
  ```

Stop the server with:
  ```
  ./scripts/stop
  ```

Print the Tor hostname:
  ```
  ./scripts/print_tor_hostname
  ```


## Quick Start (Standalone)

Set the following environment variables:

  ```
  DB_HOST=localhost
  DB_PORT=5432
  DB_NAME=nostr_ts_relay
  DB_USER=postgres
  DB_PASSWORD=postgres
  REDIS_HOST=localhost
  REDIS_PORT=6379
  REDIS_USER=default
  REDIS_PASSWORD=nostr_ts_relay
  ```

Create `nostr_ts_relay` database:

  ```
  $ psql -h $DB_HOST -p $DB_PORT -U $DB_USER -W
  postgres=# create database nostr_ts_relay;
  postgres=# quit
  ```

Start Redis and use `redis-cli` to set the default password and verify:
  ```
  $ redis-cli
  127.0.0.1:6379> CONFIG SET requirepass "nostr_ts_relay"
  OK
  127.0.0.1:6379> AUTH nostr_ts_relay
  Ok
  ```

Clone repository and enter directory:
  ```
  git clone git@github.com:Cameri/nostr-ts-relay.git
  cd nostr-ts-relay
  ```

Install dependencies:

  ```
  npm install -g knex
  npm install
  ```

Run migrations (at least once and after pulling new changes):

  ```
  npm run db:migrate
  ```

Create ~/.nostr folder:

  ```
  mkdir ~/.nostr
  ```

To start in development mode:

  ```
  npm run dev
  ```

Or, start in production mode:

  ```
  npm run start
  ```

To clean up the build, coverage and test reports run:

  ```
  npm run clean
  ```
## Tests

### Unit tests

Open a terminal and change to the project's directory:
  ```
  cd /path/to/nostr-ts-relay
  ```

Run unit tests with:

  ```
  npm run test:unit
  ```

Or, run unit tests in watch mode:

  ```
  npm run test:unit:watch
  ```

To get unit test coverage run:

  ```
  npm run cover:unit
  ```

To see the unit tests report open `.test-reports/unit/index.html` with a browser:
  ```
  open .test-reports/unit/index.html
  ```

To see the unit tests coverage report open `.coverage/unit/lcov-report/index.html` with a browser:
  ```
  open .coverage/unit/lcov-report/index.html
  ```

### Integration tests (Docker Compose)

Open a terminal and change to the project's directory:
  ```
  cd /path/to/nostr-ts-relay
  ```

Run integration tests with:

  ```
  npm run docker:test:integration
  ```

And to get integration test coverage run:

  ```
  npm run docker:cover:integration
  ```

### Integration tests (Standalone)

Open a terminal and change to the project's directory:
  ```
  cd /path/to/nostr-ts-relay
  ```

Set the following environment variables:

  ```
  DB_HOST=localhost
  DB_PORT=5432
  DB_NAME=nostr_ts_relay_test
  DB_USER=postgres
  DB_PASSWORD=postgres
  DB_MIN_POOL_SIZE=1
  DB_MAX_POOL_SIZE=2
  ```

Then run the integration tests:

  ```
  npm run test:integration
  ```

To see the integration tests report open `.test-reports/integration/report.html` with a browser:
  ```
  open .test-reports/integration/report.html
  ```

To get the integration test coverage run:

  ```
  npm run cover:integration
  ```

To see the integration test coverage report open `.coverage/integration/lcov-report/index.html` with a browser.

  ```
  open .coverage/integration/lcov-report/index.html
  ```

## Configuration

You can change the default folder by setting the `NOSTR_CONFIG_DIR` environment variable to a different path.

Run nostr-ts-relay using one of the quick-start guides at least once and `~/.nostr/settings.json` will be created.
Any changes made to the settings file will be read on the next start.

A sample settings file is included at the project root under the name `settings.sample.json`. Feel free to copy it to `~/.nostr/settings.json`
if you would like to have a settings file before running the relay first.

See [CONFIGURATION.md](CONFIGURATION.md) for a detailed explanation of each environment variable and setting.
## Dev Channel
