Package Exports
- wrapper-webpack-plugin
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (wrapper-webpack-plugin) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage
var WrapperPlugin = require('wrapper-webpack-plugin');
The WrapperPlugin class has a single parameter, an object with a header and/or footer properties. Header text will
be prepended to the output file, footer text will be appended. These can be either a string or a function. A string
will simply be a appended/prepended to the file output. A function is expected to return a string, and will receive the
name of the output file as an argument.
Example webpack.config #1
Wraps bundles in a self invoking function and enables strict mode:
var WrapperPlugin = require('wrapper-webpack-plugin');
module.exports = {
// other webpack config here
plugins: [
// strict mode for the whole bundle
new WrapperPlugin({
header: '(function () { "use strict";\n',
footer: '\n})();'
})
]
};Example webpack.config #2
Prepends bundle with a doc comment:
var WrapperPlugin = require('wrapper-webpack-plugin');
module.exports = {
// other webpack config here
plugins: [
new WrapperPlugin({
header: function (fileName) {
return '/*! file: ' + fileName + ', created by dev123 */\n';
}
})
]
};Example webpack.config #2
A slightly more complex example using lodash templates:
var WrapperPlugin = require('wrapper-webpack-plugin');
var template = require('lodash.template');
var pkg = require('./package.json');
var tplParams = {
appName: 'myapp',
author: 'dev123',
version: pkg.version
};
module.exports = {
// other webpack config here
plugins: [
// prepend build date to code
new WrapperPlugin({
header: function () {
return template('/*! <%= appName %> v<%= version %> | <%= author %> */\n')(tplParams);
}
})
]
};
