How do plugins work in Gulp?
They can change the filename, metadata, or contents of every file that passes through the stream. Plugins from npm - using the "gulpplugin" and "gulpfriendly" keywords - can be browsed and searched on the plugin search page. Each plugin should only do a small amount of work, so you can connect them like building blocks.
What is a gulp stream?
By using gulp streams, you can apply many transformations to your files while in memory before anything is written to the disk—significantly speeding up your build process. Connecting plugins
What should a gulp task return?
They should always return streams that produce and/or consume Vinyl objects. Each gulp task is an asynchronous JavaScript function that either accepts an error-first callback or returns a stream, promise, event emitter, child process, or observable. Due to some platform limitations, synchronous tasks aren't supported.
What is SemVer in Gulp?
Gulp is made up of many small modules that are pulled together to work cohesively. By utilizing semver within the small modules, we can release bug fixes and features without publishing new versions of gulp. Often, when you don't see progress on the main repository, work is being done in one of these modules.

What is glob in file system?
A glob is a string of literal and/or wildcard characters, like *, **, or !, used to match filepaths. Globbing is the act of locating files on a file system using one or more globs.
What is a glob base?
A glob base - sometimes called glob parent - is the path segment before any special characters in a glob string. As such, the glob base of /src/js/**.js is /src/js/. All paths that match the glob are guaranteed to share the glob base - that path segment can't be variable.
What is a gulp task?
Each gulp task is an asynchronous JavaScript function - a function that accepts an error-first callback or returns a stream, promise, event emitter, child process, or observable ( more on that later ). Due to some platform limitations, synchronous tasks aren't supported, though there is a pretty nifty alternative.
What is Gulp's composition method?
Gulp provides two powerful composition methods, series () and parallel (), allowing individual tasks to be composed into larger operations. Both methods accept any number of task functions or composed operations. series () and parallel () can be nested within themselves or each other to any depth. To have your tasks execute in order, use ...
What is gulp in JavaScript?
Gulp allows you to use existing JavaScript knowledge to write gulpfiles or to use your experience with gulpfiles to write plain JavaScript. Although a few utilities are provided to simplify working with the filesystem and command line, everything else you write is pure JavaScript.
What is a gulp file?
A gulpfile is a file in your project directory titled gulpfile.js (or capitalized as Gulpfile.js, like Makefile), that automatically loads when you run the gulp command. Within this file, you'll often see gulp APIs, like src (), dest (), series (), or parallel () but any vanilla JavaScript or Node modules can be used. Any exported functions will be registered into gulp's task system.
Can you write a gulpfile?
You can write a gulpfile using a language that requires transpilation, like TypeScript or Babel, by changing the extension on your gulpfile.js to indicate the language and install the matching transpiler module.
What is a Gulp plugin?
Gulp plugins are Node Transform Streams that encapsulate common behavior to transform files in a pipeline - often placed between src () and dest () using the .pipe () method. They can change the filename, metadata, or contents of every file that passes through the stream.
Does Gulp use plugins?
Not everything in gulp should use plugins. They are a quick way to get started, but many operations are improved by using a module or library instead. Plugins should always transform files. Use a (non-plugin) Node module or library for any other operations.
