{
  "a": 1,
  "b": {
    "c": 2
  }
}

path/to/files/bar/second.yml

{
  "x": "string",
  "y": false
}

Usage

  "foo": {
    "first": {
      "a": 1,
      "b": {

Loading directories

By default, directoryLoader comes with JSON and YAML loader. You can change these loaders with .add() and .remove() methods.

Because of there is two loaders as default, in the example below, YAML loader will be removed. You can remove loaders by using their extensions.

import directoryLoader from 'teyfik-directory-loader';

directoryLoader('path', 'to', 'files').remove('yml').load();

Adding loader

Also you can add your custom loaders following this example:

directoryLoader('path', 'to', 'files')
  .add('xml', (input) => parseXML(input))
  .load();

Removing loader

While removing a loader, any matching extension will remove the loader. Therefore both of the following approaches will work properly.

i By default, YAML loader matches both *.yml and *.yaml extensions.

Removing by yml extension:

directoryLoader('json-and-yaml-files').remove('yml').load();

Removing by yaml extension:

directoryLoader('json-and-yaml-files').remove('yaml').load();

Clearing all loaders

directoryLoader().clear().load();

Updating open files limit

You can set maximum number of open files at a time. This is useful when you are working with too many files. The default value is Infinity

directoryLoader('too-many-files').openFiles(5000).load();

Updating max files limit

You can set a limit for total number files to be loaded. This is useful when you are working with too many files. The default value is Infinity

directoryLoader('too-many-files').maxFiles(10000).load();
