gulp-notify

notification plugin for gulp

Information

Note: Without overriding the notifier, Mac OS X >= 10.8 or as of v0.3.2, Linux with notify-send installed is required for this to run. After version 1.1.0 this now supports Growl natively.

Usage

First, install gulp-notify as a development dependency:

npm install --save-dev gulp-notify

Then, add it to your gulpfile.js:

var notify = require("gulp-notify");
gulp.src("./src/test.ext")
  .pipe(notify("Hello Gulp!"));

Or with template

var notify = require("gulp-notify");
gulp.src("./src/test.ext")
  .pipe(notify("Found file: <%= file.relative %>!"));

See examples for more og the API section for various inputs.

Notes/tip

gulp-notify passes on the vinyl files even on error. So if you are using gulp-plumber the run will not break if the notifier returns an error.

If you want to notify on errors gulp-plumber can be used to not break the run and force you to have to restart gulp.

You can use notify.onError() as the errorHandler for gulp-plumber like this:

gulp.src("../test/fixtures/*")
      .pipe(plumber({errorHandler: notify.onError("Error: <%= error.message %>")}))
      .pipe(through(function () {
        this.emit("error", new Error("Something happend: Error message!"))
      }));

API

notify(String)

A message to notify per data on stream. The string can be a lodash template as it is passed through gulp-util.template.

notify(Function)

Type: function(VinylFile)

The result of the function is used as message. Vinyl File from gulp stream passed in as argument.

The returned string can be a lodash template as it is passed through gulp-util.template.

If false is returned from the function the notification won't run.

notify(options)

Options are passed onto the reporter, so on Windows, you can define Growl host and so on. See node-notifier for more information

options.onLast

Type: Boolean Default: false

If the notification should only happen on the last file of the stream. Per default a notification is triggered on each file.

options.message

Type: String Default: File path in stream

The message you wish to attach to file. The string can be a lodash template as it is passed through gulp-util.template.

Example: Created <%= file.relative %>.

as function

Type: Function(vinylFile)

See notify(Function).

options.title

Type: String Default: "Gulp Notification"

The title of the notification. The string can be a lodash template as it is passed through gulp-util.template.

Example: Created <%= file.relative %>.

as function

Type: Function(vinylFile)

See notify(Function).

options.templateOptions

Type: Object Default: {}

Object passed to the lodash template, for additional properties passed to the template.

Examples:

gulp.src("../test/fixtures/*")
    .pipe(notify({
      message: "Generated file: <%= file.relative %> @ <%= options.date %>",
      templateOptions: {
        date: new Date()
      }
    }))

options.notifier

Type: Function(options, callback) Default: node-notifier module

Swap out the notifier by passing in an function. The function expects two arguments: options and callback.

The callback must be called when the notification is finished. Options will contain both title and message.

See notify.withReporter for syntactic sugar.

notify.withReporter(Function)

Type: Reporter

Wraps options.notifier to return a new notify-function only using the passed in reporter.

Example:

var custom = notify.withReporter(function (options, callback) {
  console.log("Title:", options.title);
  console.log("Message:", options.message);
  callback();
});

gulp.src("../test/fixtures/1.txt")
    .pipe(custom("This is a message."));

This will be the same as

gulp.src("../test/fixtures/1.txt")
    .pipe(notify({
      message: "This is a message."
      notifier: function (options, callback) {
        console.log("Title:", options.title);
        console.log("Message:", options.message);
        callback();
      }
    }));

But much, much prettier.

notify.onError()

The exact same API as using notify(), but where a vinyl File is passed, the error object is passed instead.

Example:

gulp.src("../test/fixtures/*")
      .pipe(through(function () {
        this.emit("error", new Error("Something happend: Error message!"))
      }))
      .on("error", notify.onError(function (error) {
        return "Message to the notifier: " + error.message;
      }));

Or simply:

gulp.src("../test/fixtures/*")
      .pipe(through(function () {
        this.emit("error", new Error("Something happend: Error message!"))
      }))
      .on("error", notify.onError("Error: <%= error.message %>"));

gulp.src("../test/fixtures/*")
      .pipe(through(function () {
        this.emit("error", new Error("Something happend: Error message!"))
      }))
      .on("error", notify.onError({
        message: "Error: <%= error.message %>",
        title: "Error running something"
      }));

The onError() end point does support lodash.template.

notify.logLevel(level)

Type: Integer Default: 2

Set if logger should be used or not. If log level is set to 0, no logging will be used. If no new log level is passed, the current log level is returned.

• 0: No logging
• 1: Log on error
• 2: Log both on error and regular notification.

If logging is set to > 0, the title and message passed to gulp-notify will be logged like so:

➜  gulp-notify git:(master) ✗ gulp --gulpfile examples/gulpfile.js one
[gulp] Using file /Users/example/gulp-notify/examples/gulpfile.js
[gulp] Working directory changed to /Users/example/repos/gulp-notify/examples
[gulp] Running 'one'...
[gulp] Finished 'one' in 4.08 ms
[gulp] gulp-notify: [Gulp notification] /Users/example/gulp-notify/test/fixtures/1.txt

Examples

To see all examples run from root:

$ gulp --gulpfile examples/gulpfile.js --tasks
[gulp] Using file /Users/example/gulp-notify/examples/gulpfile.js
[gulp] Working directory changed to /Users/example/gulp-notify/examples
[gulp] Tasks for /Users/example/gulp-notify/examples/gulpfile.js

[gulp] ├── template

[gulp] ├── function
[gulp] ├── onlast
[gulp] ├── error
[gulp] └── customError

To run an example:

$ gulp --gulpfile examples/gulpfile.js multiple
[gulp] Using file /Users/example/gulp-notify/examples/gulpfile.js
[gulp] Working directory changed to /Users/example/gulp-notify/examples
[gulp] Running 'multiple'...
[gulp] Finished 'multiple' in 3.75 ms

As jshint reporter

gulp-notify can easily be used as jshint reporter. As jshint exposes the result on the vinyl file we can use them in a function like so:

gulp.task('lint', function() {
  gulp.src('/src/**/*.js')
    .pipe(jshint())
    // Use gulp-notify as jshint reporter
    .pipe(notify(function (file) {
      if (file.jshint.success) {
        // Don't show something if success
        return false;
      }

      var errors = file.jshint.results.map(function (data) {
        if (data.error) {
          return "(" + data.error.line + ':' + data.error.character + ') ' + data.error.reason;
        }
      }).join("\n");
      return file.relative + " (" + file.jshint.results.length + " errors)\n" + errors;
    }));
});

If you use a function for message in gulp-notify, the message won't be shown. This is true for both direct use of function and { message: function () {}}.
