前端构建之gulp与常用插件

gulp是什么?

http://gulpjs.com/ 相信你会明白的!

与著名的构建工具grunt相比,有什么优势呢?

  1. 易于使用,代码优于配置
  2. 高效,不会产生过多的中间文件,减少I/O压力
  3. 易于学习,API非常少,你能在很短的事件内学会gulp

一般的gulpfile文件(采用coffee编写)

首先是,node应用程序:

gulp = require(‘gulp‘)
runSequence = require(‘run-sequence‘) coffee = require(‘gulp-coffee‘)
gutil = require(‘gulp-util‘)
del = require(‘del‘)
nodemon = require(‘gulp-nodemon‘)
argv = require(‘yargs‘).argv
rename = require(‘gulp-rename‘)
browserSync = require(‘browser-sync‘)
reload = browserSync.reload # 处理参数
isDebug = not (argv.r || false) # --入口任务-----------------------------------------------------------------
gulp.task(‘default‘, (callback)->
runSequence(
[‘clean‘]
[‘coffee-server‘, ‘copy-server‘, ‘copy-client‘, ‘coffee-client‘, ‘copy-views‘]
‘serve‘
[‘browserSync‘, ‘watch‘]
callback
)
)
# --构建相关任务---------------------------------------
gulp.task(‘clean‘, (callback)->
del([‘./dist/‘], callback)
) gulp.task(‘coffee-server‘, ->
gulp.src([
‘./src/**/*.coffee‘
‘!./src/public/**/*.coffee‘
‘!./src/views/**‘
])
.pipe(coffee({bare: true}).on(‘error‘, gutil.log))
.pipe(gulp.dest(‘./dist/‘))
) gulp.task(‘copy-server‘, ->
gulp.src([
‘./src/config*/*.json‘
‘./src/database*/*.*‘
])
.pipe(gulp.dest(‘./dist/‘))
) gulp.task(‘copy-client‘, ->
gulp.src([
‘./src/public*/**/*‘
‘!./src/public*/**/*.coffee‘
])
.pipe(gulp.dest(‘./dist/‘))
) gulp.task(‘coffee-client‘, ->
gulp.src([
‘./src/public*/**/*.coffee‘
])
.pipe(coffee({bare: true}).on(‘error‘, gutil.log))
.pipe(gulp.dest(‘./dist/‘))
) gulp.task(‘copy-views‘, ->
gulp.src(‘./src/views/**/*.html‘)
.pipe(rename({extname: ‘.vash‘}))
.pipe(gulp.dest(‘./dist/views‘))
) # --启动程序,打开浏览器任务----------------------------------------------------
nodemon_instance = undefined
gulp.task(‘serve‘, (callback)->
called = false
if not nodemon_instance
nodemon_instance = nodemon({
script: ‘./dist/index.js‘
ext: ‘none‘
})
.on(‘restart‘, ->
console.log(‘restart server......................‘)
)
.on(‘start‘, ->
if not called
called = true
callback()
)
else
nodemon_instance.emit("restart")
callback()
nodemon_instance
) gulp.task(‘browserSync‘, ->
browserSync({
proxy: ‘localhost:3000‘
port: 8888
#files: [‘./src/public/**/*‘]
open: true
notify: true
reloadDelay: 500 # 延迟刷新
})
) # --监视任务------------------------------------------------
gulp.task(‘watch‘, ->
gulp.watch([
‘./src/**/*.*‘
‘!./src/**/*.coffee‘
], [‘reload-client‘])
gulp.watch(‘./src/**/*.coffee‘, [‘reload-server‘])
) gulp.task(‘reload-client‘, (callback) ->
runSequence(
[‘copy-client‘, ‘coffee-client‘, ‘copy-views‘]
‘bs-reload‘
callback
)
) gulp.task(‘reload-server‘, (callback) ->
runSequence(
[‘copy-server‘, ‘coffee-server‘]
‘serve‘
‘bs-reload‘
callback
)
) gulp.task(‘bs-reload‘, ->
browserSync.reload()
)

接下来是前端网站:

gulp = require(‘gulp‘)
gutil = require(‘gulp-util‘)
coffee = require(‘gulp-coffee‘)
del = require(‘del‘)
runSequence = require(‘run-sequence‘)
browserSync = require(‘browser-sync‘)
historyApiFallback = require(‘connect-history-api-fallback‘)
# 入口点
gulp.task(‘default‘, ->
runSequence(
[‘clean‘]
[‘copy‘]
[‘serve‘]
)
) gulp.task(‘copy‘, ->
gulp.src([
‘./src/**/*.*‘
‘!./src/**/*.coffee‘
‘!./src/**/*.less‘
])
.pipe(gulp.dest(‘./dist‘))
) gulp.task(‘clean‘, (callback)->
del([‘./dist/‘], callback)
) gulp.task(‘serve‘, ->
browserSync({
server: {
baseDir: "./dist"
middleware: [historyApiFallback]
}
port: 2222
})
) gulp.task(‘watch‘, ->
# do something...
)
