passing config file

[rupeshtiwari]

Hi,
I want to know is there a way I can pass config from json file ?
I wrote json file however not sure how to pass the regular expression from json file.
When I use below code it is not working

    "watchConfig": {
        "recursive": true,
        "filter": "/\\.tests.ts$/"
    },

I managed it using filter function.

const settings = {
        ...config.watchConfig,
        filter: (f: string) => new RegExp(config.watchConfig.filter).test(f),
    };
