Watch-uglify NPM

watch-uglify

Watches for changes to javascript files and runs them through uglify to minify them.

Getting Started

Install watch-uglify via NPM:

npm install watch-uglify

Then require it to use it:

var watchUglify = require("watch-uglify");

var srcDir = ".";
var destDir = "/tmp/watchBabel";
var options = { glob: "**/*.js" };
var watcher = watchUglify(srcDir, destDir, options);
watcher.on("ready", function() { console.log("ready"); });
watcher.on("success", function(filepath) {
  console.log("Minified ", filepath);
});
watcher.on("failure", function(filepath, e) {
  console.log("Failed to minify", filepath, "(Error: ", e);
});
watcher.on("delete", function(filepath) {
  console.log("Deleted file", filepath);
});

By default watchUglify is persistent, which means it will run even after the initial minification pass. You can close the watcher with watcher.close().

API

`watchUglify(srcDir, destDir, [options])`

srcDir is the source directory to watch.
destDir is the path to the destination directory. The directory will be created if it does not already exist.
options is an optional set of configuration entries, as described in the Options section below.

Options

persistent (default: true). If true continue to watch the srcDir for changes after the initial minification. To close a persistent watcher use watcher.close().
delete (default: true). When true a delete of a file in srcDir after the ready event will cause the associated file in destDir to be removed.
rename (default: { suffix: ".min" }). Applies a transform to the file name in the destination directory. For example, if the input is script.js then the output will be script.min.js by default. See rename for rename options.
outSourceMap (default: undefined). If defined, generates a source map for the minified file by applying rename to the destination file name. For example, if the destination file name is script.min.js and outSourceMap = { extname: ".js.map" } then a source map will be generated with the name script.min.js.map.
uglify (default: {}). Any options to send to uglify for minification.
