Usage

From File

Example loading from file (from tests) :

import * as api from "@frenchex/config-api"

const config = await api.fromFile({
    env: {env: 'dev'},
    file: path.join(testResourcesRootPath, 'js.js'),
    root: testResourcesRootPath
})

const foobar = await config.get<string>('foo.bar');
const foobar2 = await config.get<string>('foo.foobar');
const foo = await config.get<{ bar: string, foobar: string }>('foo');
const promise = await config.get<string>('promise');

expect(foobar).to.be.equal('foobar');
expect(foobar2).to.be.equal('foobarfoobar');
expect(foo).to.be.deep.equal({bar: 'foobar', foobar: 'foobarfoobar'});
expect(promise).to.be.deep.equal('resolved');

From JS object

Example loading config from object (from tests):

const config = await api.fromDeclaration({
    $: {
        foo: {
            bar: 'foobar'
        }
    }
})

const bar = await config.get<string>('foo.bar');
expect(bar).to.be.equal('foobar');

From File & JS object

You can also do both

const config = await api.fromFile({
    env: {env: 'dev'},
    file: path.join(testResourcesRootPath, 'js.js'),
    root: testResourcesRootPath,
    $: {
        "imports": ['my_file_%env%.json'],  
    }
})
