Denon

Like nodemon, but made in deno. (Also a deno style file watcher)

Install

To install denon simply enter the following into a terminal:

deno install denon --allow-read --allow-run https://deno.land/x/denon/denon.ts

Usage

To use denon simply think of denon as an alternative to deno run which accepts all the same flags if no flags or configuration has been set.

Usage:
    denon [OPTIONS] [DENO_ARGS] [SCRIPT] [-- <SCRIPT_ARGS>]

OPTIONS:
    -c, --config <file>     A path to a config file, defaults to [default: .denonrc | .denonrc.json]
    -d, --debug             Debugging mode for more verbose logging
    -e, --extensions        List of extensions to look for separated by commas
    -f, --fullscreen        Clears the screen each reload
    -h, --help              Prints this
    -i, --interval <ms>     The number of milliseconds between each check
    -m, --match <glob>      Glob pattern for all the files to match
    -q, --quiet             Turns off all logging
    -s, --skip <glob>       Glob pattern for ignoring specific files or directories
    -w, --watch             List of paths to watch separated by commas

DENO_ARGS: Arguments passed to Deno to run SCRIPT (like permisssions)

Configuration

Denon supports local configuration files. The default filenames for these are .denonrc or .denonrc.json and are written in json. They can also be specified by using the --config <file> flag. These configuration allow for even more features then the command line flags although command line flags always overrides the configuration file options. All of the options in the configuration file are optional and will be set to their default if nothing else is specified.

Example configuration with all of the possible configuration values set to something:

{
    "files": [
        "main.ts"
    ],
    "quiet": false,
    "debug": true,
    "fullscreen": true,
    "extensions": [
        ".js",
        ".ts",
        ".py",
        ".json"
    ],
    "interval": 500,
    "watch": [
        "source/",
        "tools/"
    ],
    "deno_args":[
        "--allow-net",
        "--import-map=import-map.json"
    ],
    "execute": {
        ".js": ["deno", "run"],
        ".ts": ["deno", "run"],
        ".py": ["python"]
    }
}
