Starting a service

// Export service(s)
const { startMongoDb } = require('@dashevo/dp-services-ctl');
// This is optional. Default options listed in options class
const options = {
  port: 27017, // mongoDB port
};

// Start service
const mongo = await startMongoDb(options);

// Get mongo client
const client = await mongo.getClient();

// Stop mongoDB
await mongo.remove();

Use many method to start several instances:

const { startMongoDb } = require('@dashevo/dp-services-ctl');

// This is optional. Default options listed in options class
const options = {
  port: 27017, // mongoDB port
};

// Start two services
const mongoNodes = await startMongoDb.many(2,options);

// Get peer IDs
const [client1, client2] = await Promise.all(
  mongoNodes.map(mongo => mongo.getClient()),
);

// Stop mongoDB nodes
await Promise.all(
  mongoNodes.map(mongo => mongo.remove()),
);

Services configuration

Each service has default options which can be overwritten in three ways:

  1. Pass options as plain JS object to start[service] or create[service] methods
  2. Pass instance of options class to start[service] or create[service] methods
  3. Pass default options as plain JS object to setDefaultCustomOptions method of options class

Integration with Mocha

Services Mocha hooks provide automation for your mocha tests:

// Export service(s) with mocha hooks
const { mocha: { startMongoDb } } = require('@dashevo/dp-services-ctl');

describe('Test suite', () => {
  let mongoClient;

  startMongoDb().then(mongo => () => {
    mongoClient = mongo.getClient();
  });

  it('should do something', async () => {
    const collection = mongoClient.db('test').collection('syncState');
    const count = await collection.countDocuments({});

    expect(count).to.equal(0);
  });
});
