Anatomy of a JavaScript/Node project.

Directory structure for JavaScript/Node Projects

While the following structure is not an absolute requirement or enforced by the tools, it is a recommendation based on what the JavaScript and in particular Node community at large have been following by convention.

  • src/ is intended for code that needs to be manipulated before it can be used
