A small JavaScript library that lets you make JSONP requests using the same promise-based API as the native Fetch API. It provides a global fetchJsonp function with configurable callback names and timeouts.

Use cases

• make JSONP requests with a fetch-like API
• fetch cross-domain JSON from legacy APIs that only support JSONP
• customize the JSONP callback parameter and function name
• set timeouts on JSONP requests
• parse JSONP responses as promises

When to choose

• you need to consume a legacy third-party API that only supports JSONP
• you want a fetch-style promise API for JSONP in the browser
• you need configurable callback names and request timeouts for JSONP

When to avoid

• the API supports CORS and you can use standard fetch
• you need POST or other HTTP methods since JSONP is GET-only
• you are building a server-side application where JSONP is irrelevant
• you are concerned about JSONP security implications in modern apps
