Loopback in node js11/7/2023 ![]() I recommend you to mimic my library versions for this tutorial, or at least check if your versions are compatible. Please remember that, if reproducing any steps below gives you trouble, it might be a problem of incompatibility between my versions and yours. The MEAN world is highly dynamic and new versions get cleared and released frequently, so you might have a different one. Strongloop will also be added in the PATH, so you can run it from anywhere.įor the examples I run in this article, note that I use the version above. It means your strongloop installation will be global. Install it using npm: npm install -g strongloop A free version of API Connect called API Connect Essentials is available for developers to install, free of charge. Some features are still available only in Arc but these will be added to API Connect in the next few months.ĪPI Connect also provides its own command-line tool, integrated with API management and gateway features. It includes a graphical tool with many of the API composition features of StrongLoop Arc, plus assembly and testing of API Gateway policies using the local Micro Gateway. As they put it:īuilding on LoopBack’s success as an open-source Node.js framework, IBM API Connect provides the newest tools to use with LoopBack projects. ![]() LoopBack is a highly-extensible, open-source Node.js framework. IBM and the StrongLoop team are committed to maintaining and improving LoopBack as an open-source project. If you have a Mac and brew, simply run: brew install mongodb & mongod , while in Ubuntu the command is sudo apt-get -y install mongodb .ĭon’t forget to check version, in order to make sure everything is all right: mongod -version You can install MongoDB following the instructions here. Mongo stores data in a JSON-like format and allows the user to perform SQL-like queries against it. MongoDB is a document-oriented NoSQL database, so we could say it is Big Data-ready. However, in this article I have chosen to use MongoDB, in order to stay true to the MEAN stack. There is a large variety of data storage options available to every programmer. ![]() Make sure you treat any errors and warnings before continuing. Either way, if the installation was successful, you can check Node’s and NPM’s installed versions like this: node -v ![]() Ubuntu users can use nvm to install NodeJS. Or, alternatively, if you are using Mac and brew, run brew install nodejs in the console. To install it, go to NodeJS Website and follow the instructions. In fact, we will run our NodeJS code on the server. NodeJSĪlthough NodeJS is a JavaScript-based programming language, it runs outside the browser. You might be interested in validations, charts or complex animations. I won’t talk about Angular, but if you are interested, be sure to check out our articles on the topic. Node and Express are the foundations upon which LoopBack is built and are bundled here as well. Throughout this article, I will use three of MEAN’s four components: MongoDb, Node and Express. MEAN comprises MongoDB, Express, AngularJS and NodeJS. One of the most popular approaches is MEAN, a JavaScript stack for building web sites and web applications. This makes it easier for servers to communicate not only with a web browser, but also with a variety of mobile devices, without having to change one single line of code. Recent years have seen a shift from classical web applications to a Back-End and Front-End segregation, in modern one-page applications. That being said, the following example is for a task management (TODO) application. With Node.js and LoopBack, you can quickly create dynamic end-to-end REST APIs. Not a Node.js kind of dev? Then check out our articles on converting between web frameworks and programming languages ( part 1 and part 2 – data). For more details on our Node.js experience, you can browse our technology stack. LoopBack is a highly extensible, open-source Node.js framework. In this article I will show you how to use LoopBack to create a RESTful API. It is also stateless, cache-able and has a property called idempotence (for most of its verbs), which means that multiple identical requests have the same cumulated side effects as a single request would. It is an architecture that allows client-server communication through a uniform interface. REST stands for Representational State Transfer.
