How can I type data from a JSON file in TypeScript?

Simple answer:

1. enable it in the TS config.

"compilerOptions": {
    "resolveJsonModule": true,
}

2. Pull the json prop into type def: type sampleProp = typeof jsonDataProp;

When you want to ensure that the JSON shows up as an optional prop (maybe defined later etc):

type UcpConfig = Partial<GeneratedUcpConfig>;

Tells TS that GeneratedUcpConfig might have props on it, or might be {}.
