lilconfig

Lilconfig now supports loading ESM configuration files.

ESM configs can be searched or loaded via async API only.

ESM syntax can be valid in either

• .js and .mjs files in projects with "type": "module" in package.json
• .mjs files in projects that use commonjs

Thanks for pushing this feature @marekdedic

BREAKING CHANGES

• Cache support enabled by default
• Drop support for Node v10 & v12

New cache feature

Lilconfig now can cache results in between searches within the same nodejs process. If you are reusing the searcher to look up configuration files, you will get much faster configuration lookups.

Otherwise you can disable it in options using the new cache key

lilconfig('myapp', {cache: false})

The default search places for configuration now also searches in the following files:

• .config/${name}rc
• .config/${name}rc.json
• .config/${name}rc.js
• .config/${name}rc.cjs

This version should nicely correlate with cosmiconfig v7.1.0

Thanks for reporting @edgan 👏

Thanks to @michael42 who reported and fixed a bug for async loaders in lilconfig function 👏

You can now add support to ESM configs by providing a custom loader

import {lilconfig} from 'lilconfig';

const loadEsm = filepath => import(filepath);

lilconfig('myapp', {
    loaders: {
        '.js': loadEsm,
        '.mjs': loadEsm,
    }
})
    .search()
    .then(result => {
        result // {config, filepath}

        result.config.default // if config uses `export default`
    });

Thanks to @iiroj for highlighting a bug in okonet/lint-staged/issues/1034 where relative paths did not work appropriately when passed to load methods. This bug has been fixed and tested to make sure this would not happen again 🙂

There were also a few minor improvements:

• Dev dependencies update
• Include nodejs v14 and v16 into PR checks
• Add missing .yml key in add loaded example in readme

This release contains a fix for unix root directory. Please see #17 for more information

Thank you @JounQin for the PR 🙌

Lilconfig got future proof by removing the usage of deprecated nodejs api.

Thanks to @jeetiss & @TrySound 👏

• Fixed: no more infinite loop in Windows.

lilconfig v2 is supposed to mimic the functionality of cosmiconfig v7

The breaking changes are the same. To learn more about cosmiconfig v7 click here.

After carefully testing compatibility with cosmiconfig, lilconfig's first major release is finally ready.

Type fix

• lilconfig(name).search([searchPlace]) argument should be optional. Thanks @lttb 🎉

Smaller size

• Since no external modules are used, ts compiler option esModuleInterop was disabled to prevent typescript from inlining import helpers into the transpiled code.
