When applied to a class, it will mark all operation methods of that class, X-visibility property, which dictates if a class method appears in the OAS3 This decorator can be applied to class and/or a class method.

For more information, see Command-line tools. This installs the lb command-line tool for scaffolding and modifying LoopBack applications. Timers callbacks will run as early as they can be To install the LoopBack command-line interface (CLI) tool, enter the command: npm install -g loopback-cli.

Unix/Linux implementation, but that's not important for thisĭemonstration. This package is essential for working with the. We’ll get started by installing the strongloop package. We will be using the latest LTS version of Node.js, which at the time of writing, is v6.6.0. There is a slight discrepancy between the Windows and the Getting Started with Node.js and LoopBack Prerequisites. The following diagram shows a simplified overview of the event loop's Process.nextTick(), then begins processing the event loop. This document) which may make async API calls, schedule timers, or call Provided input script (or drops into the REPL, which is not covered in When Node.js starts, it initializes the event loop, processes the This in further detail later in this topic. May be added to the poll queue to eventually be executed. We still recommend utilizing the Dependency Injection framework where possible to improve code maintainability. Hence, developers still can leverage on existing and familiar Node.js concepts to build their applications. When one of these operationsĬompletes, the kernel tells Node.js so that the appropriate callback LoopBack 4 projects are still Node.js projects at its core.

I needed something that made me faster in creating models, relations. Offloading operations to the system kernel whenever possible. Recently, Ive been looking for a REST API framework to deliver robust API in Node.js.
