MongoDB Asset Source
Mongo/GridFS backend for the travetto asset module
Install: @travetto/asset-mongo
npm install @travetto/asset-mongoThis provides a mongodb implementation of the AssetSource which is a backend for the Asset module.
Code: Mongo backend wiring
import { InjectableFactory } from '@travetto/di';
import { MongoAssetSource, MongoAssetConfig } from '@travetto/asset-mongo';
class AppConfig {
@InjectableFactory()
static getSource(cfg: MongoAssetConfig) {
return new MongoAssetSource(cfg);
}
}There is a default configuration that you can easily use, with some sensible defaults.
Code: Mongo configuration
import { Config } from '@travetto/config';
/**
* Mongo configuration as asset source
*/
@Config('mongo.asset')
export class MongoAssetConfig {
hosts: string = 'localhost'; // List of hosts, comma separated
namespace = 'app'; // Database namespace
port = 27017;
options = {}; // connection options
/**
* Compute connection URL
*/
get url() {
const hosts = this.hosts.split(',').map(h => `${h}:${this.port}`).join(',');
const opts = Object.entries(this.options).map(([k, v]) => `${k}=${v}`).join('&');
return `mongodb://${hosts}/${this.namespace}?${opts}`;
}
}Additionally, you can see that the class is registered with the @Config annotation, and so these values can be overridden using the standard Configuration resolution paths.
