Installation

Classic installation

1. Clone the repository from GitHub:

   git clone https://github.com/Prometheus-X-association/dataspace-connector.git
   

2. Install packages using pnpm

   npm i -g pnpm # If pnpm is not installed
   pnpm i
   

3. Copy the .env.sample into a .env of your choice (.env, .env.development…) and set your environment variables

   cp .env.sample .env
   cp .env.sample .env.development
   #For production
   cp .env.sample .env.production
   

4. Copy the config.sample.json into a config.json and set your configuration variables

   cp src/config.sample.json src/config.json
   #For production
   cp src/config.sample.json src/config.production.json
   

Docker

You can launch the data space connector with docker and docker compose, by using the following command at the root of the project.

You need first to add the needed variables in the config.json for the consumer and the provider inside

docker compose build && docker compose up -d

or

docker compose up -d

The docker compose file will launch the app and a mongodb container. Using your own mongodb database is possible by updating the following variable in your .env

MONGO_URI=mongodb://mongodb:27017/dataspace-connector

If you run into issues restarting docker-compose, try rebuilding and restarting the containers with sudo like so:

sudo docker-compose up --build

Local environment

Docker

You will find a directory named “sandbox” that contains a Docker Compose file for both the provider and the consumer.

/sandbox/consumer/config.json

/sandbox/provider/config.json

First, add the appropriate variables to each config.json file and then launch the container.

docker compose build && docker compose up -d

npm

You can use the following commands to launch the provider and consumer connectors via npm.

cp .env.provider .env 
cp src/config.sample.json src/config.provider.json

cp .env.consumer .env
cp src/config.sample.json src/config.consumer.json

Add the necessary variables to each file and run them in two separate terminals.

npm run provider

npm run consumer
