This module has been moved to @microsoft/loader-set-webpack-public-path

set-webpack-public-path-loader

set-webpack-public-path loader for webpack

installation

npm set-webpack-public-path-loader --save-dev

Overview

This simple loader sets the __webpack_public_path__ variable to a value specified in the arguments, optionally appended to the SystemJs baseURL property.

Usage

Documentation: Using loaders

require("set-webpack-public-path!");

Options

Inline Loader Options

scriptPath=...

Search through all script URLs on the page and use the last directory of the URL that contains the specified string.

This option is exclusive to other options. If it is set, systemJs, publicPath, and urlPrefix will be ignored.

systemJs

Use System.baseURL if it is defined. Setting this option inline will override scriptPath set by setOptions({ ... }).

publicPath=...

Use the specified path as the base public path. If urlPrefix is also defined, the public path will be the concatenation of the two (i.e. - __webpack_public_path__ = URL.concat({publicPath} + {urlPrefix}). This option takes precedence over the systemJs option. Setting this option inline will override scriptPath set by setOptions({ ... }).

urlPrefix=...

Use the specified string as a URL prefix after the SystemJS path or the publicPath option. If neither systemJs nor publicPath is defined, this option will not apply and a warning will be emitted.

Config, pre-bundle options

Options may also be set before webpack is called. This package returns a singleton, so you can require the package in your webpack.config.js and call setOptions({ ... }) to set any of the above options. For example:

var setWebpackPublicPath = require('set-webpack-public-path-loader');
 
setWebpackPublicPath.setOptions({
  systemJs: true,
  urlPrefix: process.env.BUILD_BUILDNUMBER
});

Inline options override options set in the webpack.config.

SystemJS Caveat

When modules are loaded with SystemJS (and with the , scriptLoad: true meta option) <script src="..."></script> tags are injected onto the page, evaludated and then immediately removed. This causes an issue because they are removed before webpack module code begins to execute, so the publicPath=... option won't work for modules loaded with SystemJS.

To circumvent this issue, a small bit of code is availble to that will maintain a global register of script paths that have been inserted onto the page. This code block should be appended to bundles that are expected to be loaded with SystemJS and use the publicPath=... option.

getGlobalRegisterCode(bool)

This function returns a block of JavaScript that maintains a global register of script tags. If the optional boolean paramter is set to true, the code is not minified. By default, it is minified.

Usage

var setWebpackPublicPath = require('set-webpack-public-path-loader');
var gulpInsert = require('gulp-insert');
 
gulp.src('finizlied/webpack/bundle/path')
  .pipe(gulpInsert.append(setWebpackPublicPath.getGlobalRegisterCode(true)))
  .pipe(gulp.dest('dest/path'));
