This loader will take a definition input for the manifest, and return you content for the specified browser.
### Looking for Web Extension starter
Checkout [web-extension-starter](https://github.com/abhijithvijayan/web-extension-starter) that uses this package
## Installation
Ensure you have [Node.js](https://nodejs.org) 10 or later installed. Then run the following:
```sh
# via npm
npm install --save-dev wext-manifest-loader wext-manifest-webpack-plugin
# or yarn
yarn add wext-manifest-loader wext-manifest-webpack-plugin --dev
```
## Usage
You can easily use this module together with the [`wext-manifest-webpack-plugin`](https://www.npmjs.com/package/wext-manifest-webpack-plugin) to output the `manifest.json` as part of your build process **without** any additional js bundle and with auto rebundling on file change.
**Note:** Make sure you pass a **TARGET_BROWSER** env variable with one of `chrome/firefox/edge/opera` value
#### Sample manifest with vendor prefixed keys
> **webpack.config.js**
```js
// ... other plugins
const WextManifestWebpackPlugin = require("wext-manifest-webpack-plugin");
const targetBrowser = process.env.TARGET_BROWSER;
const destPath = path.join(__dirname, 'extension');
module.exports = {
entry: {
manifest: './src/manifest.json',
// ...
},
output: {
path: path.join(destPath, targetBrowser),
filename: 'js/[name].bundle.js',
},
module: {
rules: [
{
type: 'javascript/auto', // prevent webpack handling json with its own loaders,
test: /manifest\.json$/,
use: 'wext-manifest-loader',
exclude: /node_modules/,
},
]
},
plugins: [
new WextManifestWebpackPlugin(),
// ...
],
};
```
## Options
### `usePackageJSONVersion`
Type: `Boolean`
Default: `false`
If true, updates manifest.json `version` field with `package.json` version. It is often useful for easy release of web-extension.
**webpack.config.js**
```js
module.exports = {
module: {
rules: [
{
type: 'javascript/auto', // prevent webpack handling json with its own loaders,
test: /manifest\.json$/,
use: {
loader: 'wext-manifest-loader',
options: {
usePackageJSONVersion: true,
},
},
exclude: /node_modules/,
},
],
},
};
```
## FAQs
### 1.What are vendor prefixed manifest keys
Vendor prefixed manifest keys allow you to write one `manifest.json` for multiple vendors.
```js
{
"__chrome__name": "AwesomeChrome",
"__firefox__name": "AwesomeFirefox",
"__edge__name": "AwesomeEdge",
"__opera__name": "AwesomeOpera"
}
```
if the **TARGET_BROWSER** is `chrome` this compiles to:
```js
{
"name": "AwesomeChrome",
}
```
---
Add keys to multiple vendors by seperating them with `|` in the prefix
```
{
__chrome|opera__name: "AwesomeExtension"
}
```
if the vendor is `chrome` or `opera`, this compiles to:
```
{
"name": "AwesomeExtension"
}
```
### 2. How can I conditionally set keys based on environment
```js
{
"__dev__name": "NameInDevelopment",
"__prod__name": "NameInProduction",
"__chrome|firefox|dev__description": "DescriptionInDevelopmentForSetOfBrowsers",
"__chrome|firefox|prod__description": "DescriptionInProductionForSetOfBrowsers"
}
```
if the **NODE_ENV** is `production` and the **TARGET_BROWSER** is `chrome` this compiles to:
```js
{
"name": "NameInProduction",
"description": "DescriptionInProductionForSetOfBrowsers"
}
```
else
```js
{
"name": "NameInDevelopment",
"description": "DescriptionInDevelopmentForSetOfBrowsers"
}
```
