6to5ify 中文文档教程
6to5ify
6to5 browserify 插件
Installation
$ npm install --save-dev 6to5ify
Usage
CLI
$ browserify script.js -t 6to5ify --outfile bundle.js
Node
var fs = require("fs");
var browserify = require("browserify");
var to5ify = require("6to5ify");
browserify({ debug: true })
.transform(to5ify)
.require("./script.js", { entry: true })
.bundle()
.on("error", function (err) { console.log("Error : " + err.message); })
.pipe(fs.createWriteStream("bundle.js"));
Options
browserify().transform(to5ify.configure({
blacklist: ["generators"]
}))
$ browserify -d -e script.js -t [ 6to5ify --blacklist generators ]
Enable Experimental Transforms
作者默认 6to5 的实验性转换 被禁用。 您可以通过将 experimental
作为配置选项传递来打开它们。
browserify().transform(to5ify.configure({
experimental: true
}))
$ browserify -d -e script.js -t [ 6to5ify --experimental ]
Customising extensions
默认情况下,编译扩展名为 .js
、.es
、'.es6
和 .jsx
的所有文件。 您可以通过传递扩展数组来更改此设置。
注意:这将覆盖默认值,因此如果您想使用它们中的任何一个 你必须把它们加回来。
browserify().transform(to5ify.configure({
extensions: [".6to5"]
}))
$ browserify -d -e script.js -t [ 6to5ify --extensions .6to5 ]
Relative source maps
Browserify 传递绝对路径,因此无法确定哪个文件夹 它是相对于。 您可以传递将从中删除的相对路径 带有 sourceMapRelative
选项的绝对路径。
browserify().transform(to5ify.configure({
sourceMapRelative: "/Users/sebastian/Projects/my-cool-website/assets"
}))
$ browserify -d -e script.js -t [ 6to5ify --sourceMapRelative . ]
Additional options
browserify().transform(to5ify.configure({
// Optional ignore regex - if any filenames **do** match this regex then they
// aren't compiled
ignore: /regex/,
// Optional only regex - if any filenames **don't** match this regex then they
// aren't compiled
only: /my_es6_folder/
}))
$ browserify -d -e script.js -t [ 6to5ify --ignore regex --only my_es6_folder ]
ES6 Polyfill
为方便起见,6to5 polyfill 在 6to5ify 中公开。 如果你有 一个 browserify-only 包,这可以减轻拥有的必要性 两者 6to5 & 6to5ify 安装。
// In browser code
require("6to5ify/polyfill");
6to5ify
6to5 browserify plugin
Installation
$ npm install --save-dev 6to5ify
Usage
CLI
$ browserify script.js -t 6to5ify --outfile bundle.js
Node
var fs = require("fs");
var browserify = require("browserify");
var to5ify = require("6to5ify");
browserify({ debug: true })
.transform(to5ify)
.require("./script.js", { entry: true })
.bundle()
.on("error", function (err) { console.log("Error : " + err.message); })
.pipe(fs.createWriteStream("bundle.js"));
Options
browserify().transform(to5ify.configure({
blacklist: ["generators"]
}))
$ browserify -d -e script.js -t [ 6to5ify --blacklist generators ]
Enable Experimental Transforms
By default 6to5's experimental transforms are disabled. You can turn them on by passing experimental
as a configuration option.
browserify().transform(to5ify.configure({
experimental: true
}))
$ browserify -d -e script.js -t [ 6to5ify --experimental ]
Customising extensions
By default all files with the extensions .js
, .es
, '.es6
and .jsx
are compiled. You can change this by passing an array of extensions.
NOTE: This will override the default ones so if you want to use any of them you have to add them back.
browserify().transform(to5ify.configure({
extensions: [".6to5"]
}))
$ browserify -d -e script.js -t [ 6to5ify --extensions .6to5 ]
Relative source maps
Browserify passes an absolute path so there's no way to determine what folder it's relative to. You can pass a relative path that'll be removed from the absolute path with the sourceMapRelative
option.
browserify().transform(to5ify.configure({
sourceMapRelative: "/Users/sebastian/Projects/my-cool-website/assets"
}))
$ browserify -d -e script.js -t [ 6to5ify --sourceMapRelative . ]
Additional options
browserify().transform(to5ify.configure({
// Optional ignore regex - if any filenames **do** match this regex then they
// aren't compiled
ignore: /regex/,
// Optional only regex - if any filenames **don't** match this regex then they
// aren't compiled
only: /my_es6_folder/
}))
$ browserify -d -e script.js -t [ 6to5ify --ignore regex --only my_es6_folder ]
ES6 Polyfill
As a convenience, the 6to5 polyfill is exposed in 6to5ify. If you've got a browserify-only package this may alleviate the necessity to have both 6to5 & 6to5ify installed.
// In browser code
require("6to5ify/polyfill");
