This article mainly introduces "what are the characteristics of loopback". In daily operation, I believe many people have doubts about the characteristics of loopback. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the characteristics of loopback?" Next, please follow the editor to study!

Loopback is more suitable for development teams with strong engineering and back-end background. At the same time, loopback is based on express, and it can also enjoy the inherent advantage of using any express intermediate price, which makes it easy for Node.js applications to interconnect with various devices through API.

Characteristics of LoopBack

LoopBack is an enterprise-level Node.js framework based on Express, which supports

You only need to write a little code to create a dynamic end-to-end RESTAPI

Support for mainstream data sources, such as Mongodb, SOAP, MySQL, and RESTAPI data.

Consistent Model relationship and access Control to API

You can use built-in geolocation, file services, and message push for mobile application scenarios

Provides SDK for Android, iOS and JavaScript to easily create client applications

Support for deployment of services in the cloud or on premises

It can be used like Express. In addition, LoopBack, as an enterprise-oriented Web framework, provides richer functions, which greatly improves our efficiency when we add models, permissions control, connecting data sources and other operations. For example, you can add a model by modifying the configuration and specify the data source for the model. It provides some basic models by default, such as User, which contains logic such as registration and login. We can easily inherit these built-in models and realize personalized customization. It also provides a mechanism for Hook programming. It also provides a visual debugging page and automatically generates the corresponding front-end SDK. These features will make it easier to view and manage projects when developing large Web services. This article will introduce the use of LoopBack in detail.

Installation and operation of LoopBack

StrongLoop is a utility that generates the LoopBack framework, and we install it first. Running

Npminstall-gstrongloop

After the installation is complete, you can run slc-v to see if the installation is successful (you need to establish a soft link for slc in advance).

Next, we run slcloopback, an interactive command that first prompts the user for the project name, and here we enter loopback. Next, according to the guide, fill in the corresponding information step by step. After entering the project name, we can press enter directly for the next steps. Finally, strongloop will help us create the loopback directory and create the default project files under the directory. We go to the loopback folder, run slcloopback:model, and create a model. We can enter a module name, such as cool, at will. Next, you are required to select a data source. Here, select the default value db (memory), and press enter. The next step requires you to select the base class of the model, and also choose the default value of PersistedModel, which represents that the model is connected to the persistent data source.

At this point, the study on "what are the characteristics of loopback" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
