This plugin will add a standardized Shopify comment header to transpiled files. Since transpiling via Babel is becoming one of the last steps of the build process it's handy to add some tooling around this final step.
A standard Shopify Comment Header contains:
- The license of the repo
- Current version number derived from git tag or from
package.jsonversion and last git commit
Example header:

This plugin is built ontop of babel-plugin-add-header-comment.
$ npm install babel-plugin-add-shopify-header- Simple Example
- Header Per File
- Adding To Default Header
- Adding To Header From Contents Of File
- [Adding To Header From Script Execution](Adding To Default Header From A Script Execution)
The following is an example .babelrc file using this plugin:
{
"plugins": [
"add-shopify-header"
]
}The above is useful when you just simply want to bundle one file and want to add the default Shopify header comment to that file.
If you are transpiling an entire folder and only want to add the comment header to one file (for instance src/shopify.js) do the following:
{
"plugins": [
["add-shopify-header", {
"files": [ "src/shopify.js" ]
}]
]
}If you'd like to add to the default header you can do the following:
{
"plugins": [
["add-shopify-header", {
"header": [ "This will be added under the default Shopify header" ]
}]
]
}The following will add to the default header on a per file basis
{
"plugins": [
"files":
["add-shopify-header", {
"files": {
"src/shopify.js": {
"header": [
"This is added below the default header only for src/shopify.js"
]
}
}
}]
]
}The following will show how to include the contents of the file readFromThisFile.txt under the default header. The ? charachter denotes that the path following should be read in and added to the header.
{
"plugins": [
["add-shopify-header", {
"header": [ "?readFromThisFile.txt" ]
}]
]
}Lets say you had a Node script getAdditionalContent.js that produces output you'd like to add to the header you can do the following. The ! denotes that the following script should be executed:
{
"plugins": [
["add-shopify-header", {
"header": [ "!node getAdditionalContent.js" ]
}]
]
}The following are options you can pass this Babel plugin. All options are optional:
cwd- A String which is a path to the directory that contains a LICENSE.md file and a package.json file for your project. By defaultprocess.cwd()will be used.header- An Array of strings which get appended to the standard header. This array can also contain strings starting with'!'or'?'which mean the string will not be appended but instead the string will be executed as a shell command (eg'!node someScript.js') or the path will be read in (?readInThisFile.md)files- An Array or Object that defines which files will receive the comment header. If the header does not need to be customized just pass in array of paths (eg."files": ["src/index.js", "src/index.polyfilled.js"]) or if you need to customize the header per file pass in an Object which defines customized headers (eg."files": { "src/index.js": { 'A LINE ADDED TO HEADER'}})
