jsonnet-node-loader

A loader that allows Node.js to import Jsonnet settings from an ESModule file.

Features

Support importing .jsonnet file

Installation

If you're using the npm or yarn CLI, then add the plugin by:

# yarn
$ yarn add -D jsonnet-node-loader
# or npm
$ npm install --save-dev jsonnet-node-loader

Usage

`loader` option

Specify jsonnet-node-loader in the loader option and execute the file.

Then, when the jsonnet file is imported, the evaluated value is returned.

$ node --experimental-loader jsonnet-node-loader example.mjs
{
  person1: { name: 'Alice', welcome: 'Hello Alice!' },
  person2: { name: 'Bob', welcome: 'Hello Bob!' }
}

<summary>example.mjs</summary>

js
import data from './example.jsonnet';

console.log(data);

<summary>example.jsonnet</summary>

jsonnet
{
  person1: {
    name: "Alice",
    welcome: "Hello " + self.name + "!",
  },
  person2: self.person1 { name: "Bob" },
}

Advanced usage

When using std.extVar(x), query parameters can be specified and passed when importing vars.jsonnet.

<summary>vars.jsonnet</summary>

jsonnet
{
  vars: {
    foo: std.extVar('foo'),
    var: std.extVar('bar'),
  },
}

js
import data from './vars.jsonnet?foo=1&bar=2';

console.log(data);
// { vars: { foo: '1', var: '2' } }
