This is a 'boilerplate' repository. It's intended to be forked to start new projects. However, it can also be run as a stand-alone Circuit Relay, for supporting the PSF network.

Boilerplate

This repository has been forked from the koa-api-boilerplate. It has all the same features as that boilerplate:

Koa framework for REST APIs
User management
Access and rate-limit control using JWT tokens.

This boilerplate extends that code to provide the basic features required to be a 'service provider' on the IPFS network. See this article if you're new to the concept of service providers on IPFS. These basic features include:

ipfs-coord for coordinating service providers and consumers across the IPFS network.
JSON RPC for creating an API between providers and consumers.

If you are interested in creating your own service provider on the IPFS network, fork this repository and start building.

Circuit Relay

This 'production' environment for this boilerplate sets up a series of Docker containers, orchestrated with Docker Compose. This boilerplate code can be run without modification, in order to set up a Circuit Relay and support the PSF network. You can get paid a bounty for doing so, in PSF tokens. See the section below on setting up a Production Docker Container.

Features

This project covers basic necessities of most APIs.

Koa framework for REST APIs
Authentication (passport & jwt)
Database (mongoose)
Testing (mocha)
Doc generation with apidoc
Linting using Standard
Packaged for production environment as a Docker container
ipfs-coord for coordinating peers over IPFS
JSON RPC for mirroring the REST API over IPFS

Requirements

node ^14.18.2
npm ^8.3.0
Docker ^20.10.8
Docker Compose ^1.27.4

Installation

Development Environment

Note: This software now uses an external go-ipfs IPFS node. The instructions below have not been updated to reflect this.

A development environment will allow you modify the code on-the-fly and contribute to the code base of this repository. PM2 is recommended for running this code base as an IPFS Circuit Relay.

git clone https://github.com/Permissionless-Software-Foundation/ipfs-service-provider
cd ipfs-service-provider
./install-mongo-sh
sudo npm install -g node-pre-gyp
npm install
./ipfs-service-provider.sh

Production Environment

The docker directory contains a Dockerfile for building a production deployment.

docker-compose build --no-cache
docker-compose up -d

Bring the containers up once, then take them back down with docker-compose down.
Copy the swarm.key file to ipfs-service-provider/production/data/go-ipfs/data/swarm.key.
Bring the containers back up with docker-compose up -d.

Operation Notes

There is a memory leak in the version of js-ipfs. The app is currently configured to shut down every 8 hours to flush memory. It relies on a process manager like pm2, Docker, or systemd to restart the app after it shuts down, in order to ensure continuous operation.
The PSF network operates as a private network. It does not connect or interact with the wider PSF network, relying instead on gateways to bridge the two networks, when they need to share content. This improves the performance and experience for everyone in the PSF network. To join the network, you'll need to add the swarm.key file to the IPFS data folder.
Instructions on setting up IPFS private networks.
For external installations, the swarm.key file will typically go in ~/.ipfs/swarm.key
For production Docker containers, the key would go in ipfs-service-provider/production/data/go-ipfs/data/swarm.key

Structure

The file layout of this repository differs from the koa-api-boilerplate. Instead, it follows the file layout of Clean Architecture.

Usage

npm start Start server on live mode
npm run docs Generate API documentation
npm test Run mocha tests
docker-compose build Build a 'production' Docker container
docker-compose up Run the docker container

Documentation

API documentation is written inline and generated by apidoc.
