This article summarizes LoopBack CLI tool commands.
Page Contents

Two command-line tools are available for Loopback:

  • StrongLoop command-line tools: slc loopback.
  • IBM API Connect developer toolkit CLI: apic loopback.

You use these tools to create and scaffold applications. Scaffolding simply means generating the basic code for your application. You can then extend and modify the code as desired for your specific needs.

The command-line tools provide an Application generator to create a new LoopBack application and a number of sub-generators to scaffold an application, as described in the following table. The commands are listed roughly in the order that you would use them.

Using Yeoman

Under the hood, the command-line tools use Yeoman. If you are already using Yeoman and are comfortable with it, you can install the LoopBack generator directly with the command:

$ npm install -g generator-loopback.

Then instead of using slc loopback:<command> use yo loopback:<command> instead. For example, to create a new model, use yo loopback:model.
