Installation

npm i fastify-ravendb

Usage

Register it as any other Fastify plugin. It will decorate your Fastify instance with the rvn (same name as RavenDB's CLI tool) object, and you can access and use it the same as you would do with any DocumentStore instance from the official RavenDB Node.js client.

Once the plugin is registered you can also enable automatic session handling for specific routes, via the rvn.autoSession route option. Sessions will be automatically open in the onRequest hook, requests will be decorated with the rvn object (the session, which you can use as with any session from the official client), and any pending changes will be saved onResponse.

Plugin options

You can pass the following options when registering the plugin (all of them are optional unless stated otherwise):

Route options

You can pass these options when creating routes (all of them are optional):

Examples

Basic example

import Fastify from 'fastify'
import plugin from 'fastify-ravendb'

class Person {
  constructor(name) {
    this.name = name
  }
}

const routeOptions = { rvn: { autoSession: true } }

const start = async () => {
  const fastify = Fastify({ logger: true })
  await fastify.register(plugin, {
    url: 'http://live-test.ravendb.net/',
    databaseName: 'test'
  })

  fastify.post('/people', routeOptions, async (req, reply) => {
    const person = new Person(req.body.name)

    await req.rvn.store(person)

    reply.send(person)
  })

  fastify.get('/people/:id', routeOptions, async (req, reply) => {
    const person = await req.rvn.load(`people/${req.params.id}`, Person)

    reply.send(person)
  })

  await fastify.listen({ port: 3000 })
}

start()

Advanced examples

More advanced examples are provided in the examples folder.

They require you to start the RavenDB Docker container provided in this repo. Please check Docker for more information.

Name option

Heavily inspired by @fastify-postgres. You can have multiple DocumentStore instances living together inside the Fastify namespace, and name them by passing the name parameter when registering each instance of the plugin.

import plugin from 'fastify-ravendb'

await fastify.register(plugin, {
  name: 'db1',
  url: 'http://live-test.ravendb.net/',
  databaseName: 'test'
})

await fastify.register(plugin, {
  name: 'db2',
  url: 'http://some-other-server.net/',
  databaseName: 'test2'
})

Docker

A RavenDB Docker container with a database fixture named test has been provided for running tests which require a real database and for using the advanced examples.

Run

You can start the container by simply running this command, provided that you have Docker available:

npm run docker

It will output something similar to this:

> fastify-ravendb@1.0.0 docker /Users/brianbaidal/Documents/git/fastify-ravendb
> npm run docker:run && npm run docker:data && npm run docker:url


> fastify-ravendb@1.0.0 docker:run /Users/brianbaidal/Documents/git/fastify-ravendb
> docker run -p $npm_package_config_docker_port:8080 --name fastify-ravendb -e RAVEN_ARGS='--Setup.Mode=None' -e RAVEN_Security_UnsecuredAccessAllowed=PublicNetwork -d ravendb/ravendb:ubuntu-latest

You can access RavenDB Management Studio on http://localhost:8080

Remove

When you're done you can remove the container by running this:

npm run docker:remove

Admin

You can conveniently access RavenDB CLI's admin channel running this while the container is up:

npm run docker:admin

Change port

If port 8080 is already allocated in your system, you can change the config.docker.port attribute in the package.json, then remove the container and start it again.

Reset fixtures

If at some point you want to reset the fixtures you can remove the container and start again.

Testing

In order to run the tests first you'll need to start the provided Docker container. Please check Docker for more information.

While the container is up you can run the tests with npm test.
