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
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
data.yaml
title: TOML Example
owner:
name: Tom Preston-Werner
organization: GitHub
bio: |-
GitHub Cofounder & CEO
Likes tater tots and beer.
dob: 1979-05-27T07:32:00.000Z
data.json
{
// comment
title: "TOML Example",
owner: {
name: "Tom Preston-Werner",
organization: "GitHub",
bio: "GitHub Cofounder & CEO\n\
Likes tater tots and beer.",
dob: "1979-05-27T07:32:00.000Z"
}
}
