joycon
Differences with cosmiconfig?
JoyCon is zero-dependency but feature-complete.
Install
yarn add joycon
Usage
const JoyCon = require('joycon')
const joycon = new JoyCon()
joycon.load(['package-lock.json', 'yarn.lock'])
.then(result => {
// result is {} when files do not exist
// otherwise { path, data }
})
By default non-js files are parsed as JSON, if you want something different you can add a loader:
const joycon = new JoyCon()
joycon.addLoader({
test: /\.toml$/,
load(filepath) {
return require('toml').parse(filepath)
}
})
joycon.load(['cargo.toml'])
API
constructor([options])
options
files
- Type:
string[]
The files to search.
cwd
The directory to search files.
stopDir
The directory to stop searching.
packageKey
You can load config from certain property in a package.json file. For example, when you set packageKey: 'babel', it will load the babel property in package.json instead of the entire data.
parseJSON
- Type:
(str: string) => any - Default:
JSON.parse
The function used to parse JSON string.
resolve([files], [cwd], [stopDir])
resolve([options])
files defaults to options.files.
cwd defaults to options.cwd.
stopDir defaults to options.stopDir then path.parse(cwd).root.
If using a single object options, it will be the same as constructor options.
Search files and resolve the path of the file we found.
There's also .resolveSync method.
load(...args)
The signature is the same as resolve.
Search files and resolve { path, data } of the file we found.
There's also .loadSync method.
addLoader(Loader)
interface Loader {
name?: string
test: RegExp
load(filepath: string)?: Promise<any>
loadSync(filepath: string)?: any
}
At least one of load and loadSync is required, depending on whether you're calling the synchonous methods or not.
removeLoader(name)
Remove loaders by loader name.
clearCache()
Each JoyCon instance uses its own cache.
