## Overview

This is a 'boilerplate' repository. It's intended to be forked to start new projects. Some code projects that are forks of this repository and regularly pull in changes:
- [pay-to-write database (P2WDB)](https://p2wdb.com/)
- [ipfs-bch-wallet-consumer](https://github.com/Permissionless-Software-Foundation/ipfs-bch-wallet-consumer)
- [ipfs-bch-wallet-service](https://github.com/Permissionless-Software-Foundation/ipfs-bch-wallet-service)


In addition to being forked as a boilerpalte, it can also be run as a stand-alone application to create a [Circuit Relay](https://cashstack.info/docs/local-back-end/circuit-relay), which can support the [PSF](https://psfoundation.info) IPFS network. It can also be used for experimenting with [helia-coord](https://github.com/Permissionless-Software-Foundation/helia-coord) and the [psf-bch-wallet](https://github.com/Permissionless-Software-Foundation/psf-bch-wallet) command-line wallet.

## Boilerplate

This repository has been forked from the [koa-api-boilerplate](https://github.com/christroutner/koa-api-boilerplate). It has all the same features as that boilerplate:

- [Koa](https://koajs.com/) framework for REST APIs
- User management
- Access and rate-limit control (authentication and authorization) using [JWT tokens](https://jwt.io/)
- Logging system with API access
- Email contact integration

This boilerplate extends that code to provide the basic features required to be a 'service provider' on the [IPFS](https://ipfs.io) network. This is a core concept in the [web3 Cash Stack](https://cashstack.info). These basic features include:

- [helia-coord](https://github.com/Permissionless-Software-Foundation/helia-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.

## IPFS node
This web server spins up an embedded IPFS ([Helia](https://github.com/ipfs/helia)) node. This node can be controlled and interrogated via the REST API. [psf-bch-wallet](https://github.com/Permissionless-Software-Foundation/psf-bch-wallet) is a command-line app (CLI) that can easily tap into this REST API in order to interact with the embedded IPFS node.

- npm **^8.19.4**
- Docker **^20.10.8**
- Docker Compose **^1.27.4**

## Installation

### Development Environment

A development environment will allow you modify the code on-the-fly and contribute to the code base of this repository. Ubuntu v20 is the recommended OS for creating a dev environment. Other operating systems may cause issues.

```bash
git clone https://github.com/Permissionless-Software-Foundation/ipfs-service-provider
cd ipfs-service-provider
./install-mongo-sh
npm install
npm start
```


## File Structure

The file layout of this repository differs from the koa-api-boilerplate. Instead, it follows the file layout of [Clean Architecture](https://christroutner.github.io/trouts-blog/blog/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](http://apidocjs.com/). Docs can be generated with this command:
- `npm run docs`

There is additional developer documentation in the [dev-docs directory](./dev-docs).
