This is a Webpack plugin that:
- writes text resources to the file system;
- in these resources, replaces selected paths with their public counterparts.
Plays nicely with webpack-dev-server;
see includeHash
option of the constructor.
index.jade:
doctype html
head
title My awesome app
meta( charset="utf-8" )
link( href="[[ app-*.css ]]", media="all", rel="stylesheet" )
body
p Hi everyone!
img( src="[[ images/hi.png ]]" )
script( src="[[ app-*.js ]]" )
webpack.config.js:
var ExtractTextPlugin = require('extract-text-webpack-plugin'),
PathRewriterPlugin = require('webpack-path-rewriter')
module.exports = {
entry: {
app: './scripts/index'
},
output: {
path: '_dist',
filename: 'app-[chunkhash].js',
publicPath: '/public/path/'
},
module: {
loaders: [{
test: /[/]images[/]/,
loader: 'file?name=[path][name]-[hash].[ext]'
}, {
test: /[.]styl$/,
loader: ExtractTextPlugin.extract('css?sourceMap!stylus?sourceMap')
}, {
test: /[.]jade$/,
loader: PathRewriterPlugin.rewriteAndEmit({
name: '[path][name].html',
loader: 'jade-html?' + JSON.stringify({ pretty: true })
})
}]
},
plugins: [
new ExtractTextPlugin('app-[contenthash].css', { allChunks: true }),
new PathRewriterPlugin()
]
}
After the build, _dist/index.html
will contain the following:
<!DOCTYPE html>
<head>
<title>My awesome app</title>
<meta charset="utf-8">
<link href="/public/path/app-aeeae55eaf7373d1be14ccc3fa44272d.css" media="all" rel="stylesheet">
</head>
<body>
<p>Hi everyone!</p>
<img src="/public/path/images/hi-9bc044c418aba70701582981061b685f.png">
<script src="/public/path/app-c5db2b3d825a8bccf99b.js"></script>
</body>
This plugin is content-agnostic, so it doesn't perform any parsing. You need to explicitly mark each path that needs to be rewritten.
By default, you do this by wrapping such paths inside the "[[original/path]]"
construction, which
after rewriting transforms to the "rewritten/path"
. You can control this behavior using options,
both global and per-resource.
There are two types of assets.
Most of the assets already exist in the source tree before you run the build. To rewrite paths to such assets, just mark these paths with the special construction described above.
For example, if you have views/index.jade
and images/hi.png
, in the index.jade you can specify
"[[../images/hi.png]]"
and it will be replaced with whatever public path images/hi.png
is
assigned to, e.g. "/static/images/hi-somelonghash.png"
.
Some of the assets appear as a result of the build. These include JavaScript bundles (chunks)
and files produced by
extract-text-webpack-plugin.
To rewrite path to an asset of this kind, you need to replace any variable parts of this path
with asterisk *
symbols.
For example, to rewrite path from views/index.jade
to the JS bundle which gets placed to
[hash]/scripts/app-[chunkhash].js
, the path should be specified as "[[../*/scripts/app-*.js]]"
.
Sometimes it may be inconvenient to use the default "[[...]]"
marker. It can be customized using
three options: pathRegExp
, pathMatchIndex
(index of capturing group containing extracted path)
and pathReplacer
(template of the replacement string).
For example, you can use the following options to rewrite all src
and href
HTML attributes that
end with some extension (non-relative paths are automatically skipped):
{
pathRegExp: /(src|href)\s*=\s*"(.*?\.[\w\d]{1,6})"/,
pathMatchIndex: 2,
pathReplacer: '[1]="[path]"'
}
Marks a resource for rewriting paths and emitting to the file system. Use it in conjunction with the new PathRewriter()
in the plugins list.
Takes one argument, which is either string or object. If string, then it specifies the resource's loader string along with the options, e.g.
PathRewriter.rewriteAndEmit('?name=[path][name]-[hash].[ext]')
PathRewriter.rewriteAndEmit('jade-html?pretty')
PathRewriter.rewriteAndEmit('?name=[path][name].[ext]!jade-html?pretty')
Object form allows to pass the following options:
loader
the resource's loader string.loaders
an array of loaders; mutually exclusive with theloader
option.name
the path to the output file. Defaults to"[path][name].[ext]"
. May contain the following tokens:[ext]
the extension of the resource;[name]
the basename of the resource;[path]
the path of the resource relative to thecontext
option;[hash]
the hash of the resource's content;[<hashType>:hash:<digestType>:<length>]
see loader-utils docs;[N]
content of N-th capturing group obtained from matching the resource's path against thenameRegExp
option.
nameRegExp, context
seename
.publicPath
allows to override the globaloutput.publicPath
setting.pathRegExp, pathMatchIndex, pathReplacer
allow to override options for rewriting paths in this resource.
For example:
PathRewriter.rewriteAndEmit({
name: '[path][name]-[hash].html',
loader: 'jade-html?pretty'
})
A plugin that emits to the filesystem all resources that were marked with the
PathRewriter.rewriteAndEmit()
loader. Options:
silent
don't print rewritten paths. Defaults tofalse
.emitStats
writestats.json
file. May be string specifying the file's name. Defaults totrue
.pathRegExp
regular expression for matching paths. Defaults to/"\[\[(.*?)\]\]"/
, which tests for"[[...]]"
constructions and captures the string between the braces.pathMatchIndex
the index of capturing group in thepathRegExp
that corresponds to a path. Defaults to1
.pathReplacer
template for replacing matched path with the rewritten one. Defaults to"[path]"
. May contain following tokens:[path]
the rewritten path;[N]
the content of N-th capturing group ofpathRegExp
.
includeHash
make compilation's hash dependent on contents of this resource. Useful with live reload, as it causes the app to reload each time this resources changes. Defaults tofalse
.
