6/17/2023 0 Comments Loopback js…until I started experimenting with LoopBack 4. You could say we had a love-hate relationship, but a couple of years back I tried using NestJS and was amazed! After that, I thought Nest was the best out there… I previously wasn’t a fan of using frameworks to build backend Node apps. Picking the right one requires an understanding of not only the project you’re working on, but of both frameworks and when to use them. NestJS or LoopBack: Which is best? Is there a best?Ĭhoosing between Node frameworks is super confusing, especially when there are so many great options. Contributes to open source technology documentation. Has a passion for developing cutting-edge UIs and web apps that deliver exceptional user experience, Has expertise in frontend technologies such as HTML, CSS, JavaScript, React, and Next.js, as well as backend technologies such as Node.js/Express.js and databases such as MongoDB/MySQL. * This class is used for representing the response from GitHub API.Chinedu Okere Follow Full-stack software engineer with a track record of success working in food tech, fintech, and cyber tech. At the moment, the LoopBack starter project does not come with a hot restart functionality, so let's add that first: (* ) Enable repositories: include repository imports and RepositoryMixinĪt this point, we already have the application running with a sample REST endpoint, but let's do a couple of additional steps first that will make our development easier. (* ) Enable docker: include Dockerfile and. lb-eslint ) (* ) Enable vscode: add VSCode config files (* ) Enable loopbackBuild: use helpers (e.g. (* ) Enable mocha: install mocha to run tests (* ) Enable prettier: install prettier to format code conforming to rules ? Select features to enable in the project (Press to select, to toggle all, to invert selection ) > (* ) Enable eslint: add a linter with pre-configured lint rules ? Application class name: LoopbackDemoApplication ? Project root directory: LoopBackDemoApplication ? Project description: Demonstration of basic features of LoopBack. To start off, install the LoopBack CLI which is used to scaffold projects quickly: 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.
