Terser Maven Plugin

Plugin lets you to execute Terser minification for given JavaScript files. It requires no npm or node.js, it is plain Java project (based on embedded GraalVM from version 1.4) which works perfectly combined with WebJars.

Settings, ie buttons and knobs

• verbose - no surprises, the execution becomes a bit more talkative (default: false),
• threads - number of threads to use when minifying (default: 1, will be capped on the amount of processors available)
• encoding - will apply chosen encoding during files operations (read/write) (default: Charset.defaultCharset()),
• terserSrc - readable path to standalone(!) Terser sources. It can be provided from WebJars dependency, minified or development version,
• sourceMapSrc - optional readable path to standalone(!) Source Map sources. It can be provided from WebJars dependency, minified or development version,
• sourceDir - base path for JavaScript files you are going to minify,
• targetDir - result path, note that all sub-directories from sourceDir will be preserved,
• jsFiles - list of JavaScript files (static) from sourceDir to minify,
• jsIncludes - list of JavaScript files (with simple masks */?),
• jsExcludes - list of exceptions for jsIncludes,
• suffix - optional suffix applied for every minified file,
• options - options for Terser execution
