A utility written in Go to provide reloading for Go HTTP applications.

recharge watches a Go project for changes and rebuilds the target application when changes occur. recharge operates by providing a proxy through to th target application which coordinates the building and running of the target application while being transparent to the user.

go get -u github.com/keysolutions/recharge

recharge uses a TOML configuation file to assign project-specific options. An example configuration file is found in this repository under the name recharge.conf.

RootDir = "."
Build = "go build -o ./demo/demo ./demo"
Run = "./demo/demo"
SourceAddr = ":3000"
TargetAddr = ":3001"

Possible configuration options:

If bash or sh is available on the system the build and run commands will be executed as bash -c "$COMMAND" to give greater flexibility in creating build and run command rules. When they are not available the command will fall back to being executed directly using Go's exec.Command functionality. Authors of recharge.conf files should be aware of the limitations of various systems that their projects may be run on.

recharge contains a demo application in the demo directory which is ready to be used with the included recharge.conf. Simply start the recharge application in its project root to see it in action.
