npm i teyfik-directory-loader

For the directory structure, file contents and the usage below;

.
└── path
  └── to
    └── files
      ├── foo
      | └── first.json
      └── bar
        └── second.yml

path/to/files/foo/first.json

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

path/to/files/bar/second.yml

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

import directoryLoader from 'teyfik-directory-loader';

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

{
  "foo": {
    "first": {
      "a": 1,
      "b": {
        "c": 2
      }
    }
  },
  "bar": {
    "second": {
      "x": "string",
      "y": false
    }
  }
}

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();

Also you can add your custom loaders following this example:

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

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();

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

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();

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();
