@ideal-postcodes/core-axios

Axios backed JavaScript client for api.ideal-postcodes.co.uk

@ideal-postcodes/core-axios is the Axios backed client for api.ideal-postcodes.co.uk. Axios is a promise based HTTP client for the browser and node.js and so is ideal for:

• Frameworks that utilise server side rendering (Angular, Next.js, React, etc)
• Isomorphic code (runs on browser and server)

Our JavaScript client implements a common interface defined at @ideal-postcodes/core-interface.

High level client documentation can be found at core-interface.

In depth client documentation can be found at core-interface.ideal-postcodes.dev.
