minify-runner

The minify-runner is a command-line tool designed to minify JavaScript code using different minifiers. It currently supports both SWC and Terser minifiers and allows specifying the minifier version.

Installation

To use the minify-runner, ensure you have Deno installed.

You can install the cli command with following command:

deno install --global -n minify-runner -A ./mod.ts --import-map ./deno.json

• Set MINIFY_RUNNER_CACHE_DIR env if you want to change env directory
• If not set, minify-runner creates new cache directory. Check misc/cache.ts.

Usage

The minify-runner command provides the following options and arguments:

Options

• -v, --version <name@semver:string>: Specifies the minifier name along with its version in the format name@semver. The default value is swc@1.6.7.
• -f, --file: Indicates that the code is provided by filename instead of a string.
• -d, --diff: This option enables the AST diff checker, which is used to determine if the minifier triggered any changes.
  • Note: This option is still a work in progress and not fully implemented yet.

Arguments

• <codeOrFilePath:string>: The code to be minified or the path to the file containing the code.

Minifier Options

The minifier options are stored in configuration files and are automatically applied when the minifier is executed:

• SWC: The configuration options for SWC are stored in the .swcrc file.
• Terser: The configuration options for Terser are stored in the .terserrc file.

Example commands

Directly Input Code

minify-runner -v swc@1.7.0 "const x = 1; console.log(x)"

Use File Path

minify-runner -v swc@1.7.0 -f tmp.js

Using diff option

minify-runner -v swc@1.7.0 -d "console.log(1+1);"
