This is common structure for an application folder. Normally found in most projects.

Folder structure varies by build system and programming language. Here are some standard conventions:

• src/: “source” files to build and develop the project. This is where the original source files are located, before being compiled into fewer files to dist/, public/ or build/.
• dist/: “distribution”, the compiled code/library, also named public/ or build/. The files meant for production or public use are usually located here.
• lib/: external dependencies (when included directly).
• test/: the project’s tests scripts, mocks, etc.
• node_modules/: includes libraries and dependencies for JS packages, used by Npm.
• vendor/: includes libraries and dependencies for PHP packages, used by Composer.
• bin/: files that get added to your PATH when installed.

Markdown/Text Files:

• README.md: A help file which addresses setup, tutorials, and documents the project. README.txtis also used.
• LICENSE.md: any rights given to you regarding the project. LICENSE or LICENSE.txt are variations of the license file name, having the same contents.
• CONTRIBUTING.md: how to help out with the project. Sometimes this is addressed in the README.md file.

Specific

• package.json: defines libraries and dependencies for JS packages, used by Npm.
• package-lock.json: specific version lock for dependencies installed from package.json, used by Npm.
• composer.json: defines libraries and dependencies for PHP packages, used by Composer.
• composer.lock: specific version lock for dependencies installed from composer.json, used by Composer.
• gulpfile.js: used to define functions and tasks to be run with Gulp.
• .travis.yml: config file for the Travis CI environment.
