Loopback api6/22/2023 ![]() ![]() It will expose an endpoint where you can fetch a specific issue, and then this issue will be fetched from the local cache, or from GitHub if it's not cached. For this purpose, we'll build a small application that acts like a proxy towards the GitHub issue API, but with local caching. Now that we know what LoopBack is about, let's try to implement an application that will demonstrate the usage of two common functionalities that most API backends have, such as saving to a database, and invoking an external API. Your components declare dependencies on other components, and it's up to LoopBack to wire them up. LoopBack has a DI-based context at its core, allowing for writing loosely coupled code. This way, you can easily integrate your application with other APIs without much custom code. There are numerous connectors written for LoopBack, from REST/SOAP connectors, to database connectors for relational and NoSQL databases. Many can get a project running within minutes. LoopBack comes with its CLI tool, which is great for scaffolding initial projects, or generating additional code. The OpenAPI standard is becoming widely adopted, and LoopBack makes it easy to create OpenAPI-based REST APIs. It can be a great companion to other TypeScript-based frameworks such as Angular, as frontend and backend teams will use the same programming language for the entire stack. If you like TypeScript, then you'll definitely want to consider LoopBack. ![]() LoopBack uses Express under the hood, but there are several noticeable features that make LoopBack stand out from other API frameworks: A framework such as LoopBack is usually not the first option, even though this is a relatively mature and stable framework, and backed by an IBM company called StrongLoop.Īs part of this blog post, we'll demonstrate the basic functionalities of LoopBack by building a small REST API. This framework is also usually the top choice for demonstration purposes such as proof of concepts, or tutorials, which further contributes to its popularity. This is, perhaps, the most popular web framework for Node.js. When one wants to implement a Node.js-based backend API, the first framework that usually comes to mind is Express. ![]()
