Data-Deref

Simple utility to dereference $ref references in a data document.

Usage

Examples of usage can be found in the examples directory on the repository.

Basic Usage

The module exports a deref function by default which takes a single argument, a path to the file which is to be parsed and dereferenced.

import deref from "data-deref";

deref('path/to/data.json#/path/to/reference').then(console.log);

Using with a custom parser

You can use a custom parsing function which parses data based on the extension of file being referred to as resolved by 'path.extname(...)' of the standard library.

This example uses yaml to parse the data from a .yaml file.

import deref, { config } from "data-deref";
import YAML from "yaml";

config.addFileParser(".yaml", YAML.parse);

deref('path/to/data.yaml#/path/to/reference').then(console.log);

By default, the module only uses JSON.parse(...) to parse .json files.

Mixing references from different files

You can mix references from different files by using the $ref keyword in the data document.

// target.json
{
  "foo": {
    "$ref": "ref.yaml#/value/of/foo"
  }
}

# ref.yaml
value:
  of:
    foo: "bar"

import deref from "data-deref";
import YAML from "yaml";

deref('path/to/target.json#/foo').then(console.log);
// Logs "bar" to the console
