The closest LoopBack 4 comes to being a tangible entity is the loopback-next monorepo, and maybe the lb4 CLI. There is no LoopBack 4 on NPM, like how there is LoopBack 3 ( loopback), and there is nothing that can be downloaded that would constitute as LoopBack 4. LoopBack 4 as an entity does not exist.There are two things you must know right at the beginning. Here's my take on the LoopBack 4 tutorial. On my website I am free from such guidelines, which allow me to write write tutorials the way I think they should be structured and written. However, official documentation follow certain guidelines and generally don't allow for such an approach. In my opinion, a semi-informal presentation is the best format for teaching. This post is the first among many that I will be writing on LoopBack. While we are actively addressing it and have made documentation improvement as one of our highest priorities this year, I am taking up "better learning materials for LoopBack" as a personal goal and plan to completely change the perception of LoopBack. If you know JavaScript already, it can be leaned in a day.Īs one of the core developers of LoopBack, a very frequent complaint I hear is about our "not-so-great" documentation. If you are totally new to TypeScript, I suggest you learn it and come back. Create the https server for the application. See for more details.A basic level knowledge of TypeScript is a minimal requirement for using LoopBack 4.OAuth 2.0 states that the authorization server MUST require the use of TLS with server authentication for any request sent to the authorization and token endpoints. There are two steps involved here: We customize server/server.js to add specific features for the gateway. The application is initially scaffolded using slc loopback command. The architecture is illustrated in the diagram below. A loopback application (api server) serving the REST APIs.A loopback application (api gateway) that bridges the client application and the backend api.A client application that invokes REST APIs.The test scenario consists of three components: Reverse proxy: forward the requests to the server that hosts the api endpoint. Rate limiting: controls how many requests can be made within a given time period for identified api consumers.oAuth 2.0 based authentication & authorization: authenticate client applications and authorize them to access protected endpoints with approval from resource owners.HTTPS: make sure all communication will be done with https.The gateway supports basic features listed below: Loopback-gateway is an example application to demonstrate how to build an API gateway using LoopBack. In this tutorial, we’ll build a simplified version of API gateway using LoopBack. The API gateway sits as an intermediary between the many consumers of APIs – API clients and the many producers of the APIs on the backend – API servers. Learn more… What is an API gateway?Īn API gateway is a component within systems architecture to externalize, secure and manage APIs. What’s LoopBack? It’s an open source Node.js framework for developing, managing and scaling APIs. In this blog we’ll show you how to get started with a sample application to test out the features of the gateway. The LoopBack API Gateway is open source and is the “minimum viable product” (MVP) that covers key use cases piloted with our co-development partners. In case you missed it, today we announced the availability of the open source LoopBack API Gateway. Read this announcement blog to learn more about the latest version. Note: Since the publication of this blog, the StrongLoop API Gateway was relaunched on August 5, 2015.
