Bundler

Bundler is a software dependency manager for the Ruby programming language. It helps application developers to quickly install the required Ruby libraries and packages needed for coding their applications. Bundler allows developers to track, install, and update libraries easily across multiple machines.

Bundler is part of the Ruby programming language, so it comes with the Ruby installation. It was created by Yehuda Katz and Carl Lerche in July 2009. The main concept of Bundler is to manage and maintain a project’s dependencies so you don’t have to go back and install them one by one when developing an application.

Bundler has two main functions: Gemfile Resolution and Dependencies Lock. Gemfile Resolution means that the programmer specifies the exact versions of the dependent Ruby libraries that will be used in the application development. Dependencies Lock ensures that the exact same versions of the dependencies are installed on each machine in the development process. This prevents developers from running into unexpected issues due to different library versions being used.

Bundler also allows developers to install package versions that are compatible with their application. This ensures that the libraries used are up-to-date and that the application runs smoothly without any unexpected issues.

Bundler is mostly used by developers who are creating Ruby-based web applications, but it can also be used for other types of applications. It is especially useful for quickly creating prototypes and testing new ideas. Bundler is a great tool for managing dependencies and ensuring a smooth development process.
