A better way to load your configuration files

Motivation

I needed a module to save me from having to write the same snippets of code in every project that required a config. There already existed many modules that drastically reduced the amount of code I would have to write. But I often still found myself in very simmilar situations: Like writing snippets to generate default configs. Not to mention anyting to do with directories. So that's why I made this neat little module. I hope you are able to get a simmilar amount of value from it as I

Features

• Simple, load your configs with a single line of code
• Powerful, read and write both files and directories with defaults
• Flexible, create support for formats of your needs
• TypeScript, pre-packaged type definitions
• JSDocs, together with TS type definitions enables helpful code completion in modern IDEs

Examples

Reading a raw text file

import * as mlc from "@aery/mlc";

const file: mlc.ConfigFile = await mlc.file("raw.txt") // Defaults to RawFormat format by default
    .read();

file.content;

Reading a JSON file

import * as mlc from "@aery/mlc";

const file: mlc.ConfigFile = await mlc.file("config.json") /* Associates json files with
                                                              JSONFormat format by default */
    .defaults({
        ip: "127.0.0.1",
        port: 1337
    }) // What content should default to when reading
    .read({ write_if_defaulted: true }); // Write if content was defaulted in any way after reading

file.content;

Writing a raw text file

import * as mlc from "@aery/mlc";

const file: mlc.ConfigFile = mlc.file("foo.txt"); // Defaults to RawFormat format by default

file.content = "bar";

file.write();

Reading a directory

import * as mlc from "@aery/mlc";

const directory: mlc.ConfigDirectory = await mlc.directory("recipies", new mlc.formats.JSONFormat())
    .defaults({
        "water.json": {
            steps: [ "Pour water" ]
        },
        "cereal.json": {
            steps: [
                "Pour cereal FIRST",
                "THEN pour milk"
            ]
        }
    }) // What the ConfigDirectory's ConfigFiles' content should default to when reading
    .read();

const contents: object = directory.contents();

contents["water.json"];
contents["cereal.json"];
