-The `Sourceloop` is a collection of pre-built microservices that aim to reduce time to market for Enterprise projects. Large enterprises usually face a similar set of challenges when developing cloud native platforms as part of digital transformation efforts or the creation of new products. The services are implemented as [LoopBack Extensions](https://loopback.io/doc/en/lb4/Extending-LoopBack-4.html), allowing you to install them into existing LoopBack applications or use the [LoopBack  Command-line interface](https://loopback.io/doc/en/lb4/Command-line-interface.html) to generate standalone services. Our recommended approach is to deploy these services as standalone micro-services in Docker.

 The migrations required for this service are processed during the installation automatically if you set the `SOURCELOOP_MIGRATION` env variable. The migrations use [`db-migrate`](https://www.npmjs.com/package/db-migrate) with [`db-migrate-pg`](https://www.npmjs.com/package/db-migrate-pg) driver for migrations, so you will have to install these packages to use auto-migration. Please note that if you are using some pre-existing migrations or database, they may be effected. In such scenario, it is advised that you copy the migration files in your project root, using the `SOURCELOOP_MIGRATION_COPY` env variables. You can customize or cherry-pick the migrations in the copied files according to your specific requirements and then apply them to the DB.
