Webpack is an open-source JavaScript module bundler. Webpack takes modules with dependencies and generates static assets representing those modules. It takes the dependencies and generates a dependency graph allowing web developers to use a modular approach for their web application development purposes. The bundler can be used from the command line, or can be configured using a config file which is named webpack.config.js.

Node.js is required for installing webpack. Another important aspect about webpack is that it is highly extensible by the use of loaders. Loaders allow developers to write custom tasks that they want to perform when bundling files together.

Webpack provides code on demand using the moniker code splitting. The Technical Committee 39 for ECMAScript is working on standardization of a function that loads additional code: proposal-dynamic-import.

RPM Package Manager (RPM) (originally Red Hat Package Manager; now a recursive acronym) is a package management system. The name RPM refers to the following: the .rpm file format, files in the .rpm file format, software packaged in such files, and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base.

Even though it was created for use in Red Hat Linux, RPM is now used in many Linux distributions. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3) and IBM's AIX (as of version 4).

An RPM package can contain an arbitrary set of files. The larger part of RPM files encountered are “binary RPMs” (or BRPMs) containing the compiled version of some software. There are also “source RPMs” (or SRPMs) files containing the source code used to produce a package. These have an appropriate tag in the file header that distinguishes them from normal (B)RPMs, causing them to be extracted to /usr/src on installation. SRPMs customarily carry the file extension “.src.rpm” (.spm on file systems limited to 3 extension characters, e.g. old DOS FAT).

Travis CI is a hosted, distributed continuous integration service used to build and test software projects hosted at GitHub.

Open source projects may be tested at no charge via travis-ci.org. Private projects may be tested at travis-ci.com on a fee basis. TravisPro provides custom deployments of a proprietary version on the customer's own hardware.

Although the source is technically free software and available piecemeal on GitHub under permissive licenses, the company notes that it is unlikely that casual users could successfully integrate it on their own platforms.

GitHub (originally known as Logical Awesome LLC) is a web-based hosting service for version control using git. It is mostly used for computer code. It offers all of the distributed version control and source code management (SCM) functionality of Git as well as adding its own features. It provides access control and several collaboration features such as bug tracking, feature requests, task management, and wikis for every project.

GitHub offers plans for both private repositories and free accounts which are commonly used to host open-source software projects. As of April 2017, GitHub reports having almost 20 million users and 57 million repositories, making it the largest host of source code in the world.

GitHub has a mascot, an "Octocat" called Mona, a cat with five tentacles and a human-like face.

From its initial creation XL Deploy (Deployit) was specifically designed to be an "agentless" deployment automation solution, and to bypass the need for the scripting and workflows used by other tools in order to provide an easier way to deploy to complex environments. Additionally, in conjunction with a number of plugins for Jenkins, Puppet Labs, Jboss, Websphere, Tomcat, Maven, Ansible, Docker, Visual Studio, Bamboo, VMware, Chef, XL Deploy was also designed as an extensible solution to help teams leverage their existing tooling and IT investment streamlining continuous processes.

GitLab is a web-based Git-repository manager with wiki and issue-tracking features, using an open-source license, developed by GitLab Inc.

The software was written by Dmitriy Zaporozhets and Anita Arya from India Valery Sizov from Ukraine. The code is written in Ruby. Later, some parts have been rewritten in Go. As of December 2016, the company has 150 team members and more than 1400 open-source contributors. It is used by organisations such as IBM, Sony, Jülich Research Center, NASA, Alibaba, Invincea, O’Reilly Media, Leibniz-Rechenzentrum (LRZ), CERN, and SpaceX.

Bamboo is a continuous integration and continuous deployment server developed by Atlassian. Although initially available both as an on-premises and cloud computing service, in May 2016 it was announced that the cloud version would be discontinued by end of January 2017.

Coverity is a brand of software development products from Synopsys, consisting primarily of static code analysis and dynamic code analysis tools. The tools enable engineers and security teams to find defects and security vulnerabilities in custom source code written in C, C++, Java, C#, JavaScript and more.

Before its acquisition by Synopsys, Coverity was an organization founded in the Computer Systems Laboratory at Stanford University in Palo Alto, California and with headquarters in San Francisco. In June 2008, Coverity acquired Solidware Technologies. And in February 2014, Coverity announced an agreement to be acquired by Synopsys, an electronic design automation company, for $350 million net of cash on hand.

Artifactory is a product by JFrog that serves as a binary repository manager. That said very often one will use an artifactory as a synonym of the more general binary repository, much like many people use Frigidaire or fridge to denote the refrigerator regardless if it is a Frigidaire brand or not.

The binary repository is a natural extension to the source code repository in that it will store the outcome of your build process, often denoted as artefacts. Most of the times one would not use the binary repository directly but through a package manager that comes with the chosen technology.

In most cases these will store individual application components that can later be assembled in a full product. Thus allowing a build to be broken in smaller chunks making more efficient use of resources, reducing build times, better tracking of binary debug databases etc.

Nexus manages software "artifacts" required for development. If you develop software, your builds can download dependencies from Nexus and can publish artifacts to Nexus creating a new way to share artifacts within an organization. While Central repository has always served as a great convenience for developers you shouldn't be hitting it directly. You should be proxying Central with Nexus and maintaining your own repositories to ensure stability within your organization. With Nexus you can completely control access to, and deployment of, every artifact in your organization from a single location.

FitNesse is a web server, a wiki and an automated testing tool for software. It is based on Ward Cunningham's Framework for Integrated Test and is designed to support acceptance testing rather than unit testing in that it facilitates detailed readable description of system function.

FitNesse allows users of a developed system to enter specially formatted input (its format is accessible to non-programmers). This input is interpreted and tests are created automatically. These tests are then executed by the system and output is returned to the user. The advantage of this approach is very fast feedback from users. The developer of the system to be tested needs to provide some support (classes named "fixtures", conforming to certain conventions).

Confluence is a team collaboration software. Written in Java and mainly used in corporate environments, it is developed and marketed by Atlassian. Confluence is sold as either on-premises software or as software as a service.

Atlassian released Confluence 1.0 on March 25, 2004, saying their purpose was to build "an application that was built to the requirements of an enterprise knowledge management system, without losing the essential, powerful simplicity of the wiki in the process."

Microsoft Teams is a platform that combines workplace chat, meetings, notes, and attachments. The service integrates with the company's Office 365 subscription office productivity suite, including Microsoft Office and Skype, and features extensions that can integrate with non-Microsoft products. Microsoft announced Teams at an event in New York, and launched the service worldwide on 14 March 2017.

Microsoft Teams was created, and is currently led, by Brian MacDonald, Corporate Vice President at Microsoft.

Crucible is a collaborative code review application by Australian software company Atlassian. Like other Atlassian products, Crucible is a Web-based application primarily aimed at enterprise, and certain features that enable peer review of a codebase may be considered enterprise social software.

Crucible is particularly tailored to distributed teams, and facilitates asynchronous review and commenting on code. Crucible also integrates with popular source control tools, such as Git and Subversion. Crucible is not open source, but customers are allowed to view and modify the code for their own use.
