MERGE INTO SINGLE FILE PLUGIN FOR WEBPACK

Webpack plugin to merge your source files together into single file, to be included in index.html, and achieving same effect as you would by including them all separately through







`
because your node_modules is not available in production.

with this plugin you can achieve the desired effect this way:
`javascript

const MergeIntoSingleFilePlugin = require('webpack-merge-and-include-globally');

module.exports = {
...
plugins: [
new MergeIntoSingleFilePlugin({
files: {
"vendor.js": [
'node_modules/jquery/dist/jquery.min.js',
// will work too
// 'node_modules/jquery/*/.min.js',
'node_modules/moment/moment.js',
'node_modules/moment/locale/cs.js',
'node_modules/moment/locale/de.js',
'node_modules/moment/locale/nl.js',
'node_modules/toastr/build/toastr.min.js'
],
"vendor.css": [
'node_modules/toastr/build/toastr.min.css'
]
}
}),
]

`
this generates 2 files with merged js and css content, include them into your index.html to take effect:
` html


`
now jQuery, moment and toastr are available globally throughout your application.

#### files (as object)

Object that maps file names to array of all files (can also be defined by wildcard path) that will be merged together and saved under each file name.

For example to merge jquery, classnames and humps into vendor.js, do:
`javascript
new MergeIntoSingle({
files: {
'vendor.js': [
'node_modules/jquery/*/.min.js',
'node_modules/classnames/index.js',
'node_modules/humps/humps.js'
],
'style.css': [
'example/test.css'
]
}
})
`

#### transform

Object that maps resulting file names to tranform methods that will be applied on merged content before saving. Use to minify / uglify the result.

For example to minify the final merge result of vendor.js, do:
`javascript
new MergeIntoSingle({
files: { 'vendor.js': [...] },
transform: {
'vendor.js': code => require("uglify-js").minify(code).code
}
})
`

#### files (as array)

Alternative way to specify files as array of src & dest, for flexibility to transform and create multiple destination files for same source when you need to generate additional map file for example.
`javascript
new MergeIntoSingle({
files: [{
src:[
'node_modules/jquery/*/.min.js',
'node_modules/classnames/index.js',
'node_modules/humps/humps.js'
],
dest: code => {
const min = uglifyJS.minify(code, {sourceMap: {
filename: 'vendor.js',
url: 'vendor.js.map'
}});
return {
'vendor.js':min.code,
'vendor.js.map': min.map
}
},

// also possible:
//
// dest: 'vendor.js'
},{
src: ['example/test.css'],
dest: 'style.css'

// also possible:
//
// dest: code => ({
// 'style.css':new CleanCSS({}).minify(code).styles
// })
}]
})
`

#### hash
default: false

set true to append version hash before file extension.

you can get names of generated files mapped to original by passing callback function as second argument to plugin:
`javascript
new MergeIntoSingle({ ... }, filesMap => { ... }),
`

#### transformFileName
default: undefined

also you can pass function for change output file name with hash
`javascript
new MergeIntoSingle({
...,
transformFileName: (fileNameBase, extension, hash) => ${fileName}.[${hash}]${extension},
// bundle.[somehash].js
}),

//or

new MergeIntoSingle({
...,
transformFileName: (fileNameBase, extension, hash) => ${fileNameBase}${extension}?hash=${hash},
// bundle.js?hash=somehash
}),

`

#### encoding

default: 'utf-8'

encoding of node.js reading

#### chunks

default: undefined

array of entry points (strings) for which this plugin should run only

#### separator

default: '\n'

string used between files when joining them together

working example already included in project.

to test first install npm i, then run npm run start to see it in action

and npm run build to build prod files with vendor file and index.html`.
