hotreload

:zap: CLI tool to conveniently detect and react to file changes

about

In development environments, having the ability to hot-reload your applications once the source code changes is the greatest method of making your life a little easier! Classic projects like nodemon are pretty awesome, but sometimes the huge amount of features added that aren't really necessary make those tools a bit too overkill for your use cases, which is why I created hotreload. Simply supply files you want to watch and actions to be taken once something changes!

getting started

# install using npm
npm i -g hotreload-cli

# install using yarn
yarn global add hotreload-cli

...

# Simply launch hotreload
hotreload [--config <path>]

configuration

hotreload's configuration is mostly based on the libraries found below, so you're getting the full freedom to change anything to your needs.

An example configuration:

{
  "watch": [
    {
      "path": "src/**/*.ts",
      "tasks": [
        {
          "command": "for i in `seq 1 30`; do echo $i && sleep 1; done",
          "options": {
            "shell": true
          }
        }
      ]
    }
  ]
}

reloadOptions

An optional object for configuring hot-reload-specific options such as

• shutdownGracePeriod: The time (in ms) before a SIGKILL signal is issued to the running process, defaults to one second
• reloadPeriod: An optional delay (in ms) between stopping the running processes and spinning up the new ones

options

All options passed are directly used for file-watching. A reference of available options can be found here.

watch

• options: The same as above, but used only for a specific watch target
• path: A string or array of strings containing files, directories or globs to watch
• tasks: An array of tasks to run on each event

tasks

• command: A command as a string
• options: An object of process options
