A cross platform, zero-config, dependency free, pure Go local file server that serves a directory on your file system over HTTP and automatically reloads HTML files in the browser when the document or any of its dependencies have changed.
The simplest and easiest way to compile and install this tool is by using the Go command. Simply run
go install github.com/meblum/serv/cmd/serv@latest
Running the serv command starts a local server that serves the current directory on port 8080. Use serv path/to/directory to specify a different directory to serve. Navigating to a directory will return an auto generated index of the directory, if an index.html file is present in the directory, it will be served instead. By default, all HTML documents will be injected with a tiny script which will tell the browser to reload when a change is detected.
A main design goal was to keep this tool extremely simple. A few optional flags may be set as follows:
-no-reload
serve without reloading on file update
-port int
port to serve on (default 8080)
The server adds a tiny script to served HTML files. The script keeps a long-running HTTP connection between the document and the server, and the server keeps a mapping of files the HTML document depends on. The server notifies the script when a file has changed and the script reloads the page.
You can use and extend the functionality of this tool. The module exposes a single FileServer function that returns the file server as an http.Handler. Please refer to the go doc for more information.
