vfsgen
Generates Go code that statically implements an http.FileSystem, enabling efficient embedding of assets into Go binaries.
What is vfsgen?
vfsgen is a Go library that generates static Go code implementations of http.FileSystem interfaces, allowing assets to be embedded directly into Go binaries. It solves the problem of managing external asset files in deployments by compiling them into the executable. The tool is typically used at `go generate` time to create efficient, compressed representations of directories and files.
Go developers who need to embed static assets (like web resources, templates, or configuration files) into their binaries for simplified distribution and deployment. It's particularly useful for projects building web servers, CLI tools with embedded resources, or any Go application requiring portable asset management.
Developers choose vfsgen for its simplicity centered on the standard http.FileSystem interface, efficient generated code with smart gzip compression, and seamless integration with Go's build system and `go generate`. It avoids unnecessary overhead by merging functionality that often requires multiple packages into a single, focused tool.
Overview
Takes an input http.FileSystem (likely at go generate time) and generates Go code that statically implements it.
