webpack/examples/custom-json-modules/README.md

This very simple example shows usage of a custom parser for json-modules.

Toml files can be imported like other modules without toml-loader.

# data.toml

```toml
title = "TOML Example"

[owner]
name = "Tom Preston-Werner"
organization = "GitHub"
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
dob = 1979-05-27T07:32:00Z
```

# example.js

```javascript
import data from "./data.toml";

document.querySelector('#app').innerHTML = `
  <h1>${data.title}</h1>
  <div>${data.owner.name}</div>
  <div>${data.owner.organization}</div>
  <div>${data.owner.bio}</div>
  <div>${data.owner.dob}</div>
`;
```

# webpack.config.js

```javascript
const toml = require("toml");

module.exports = {
	module: {
		rules: [
			{
				test: /\.toml$/,
				type: "json",
				parser: {
					parse(input) {
						return toml.parse(input);
					}
				}
			}
		]
	}
};
```
