    Ideal Postcodes API Typings

    Typings for the Ideal Postcodes API (api.ideal-postcodes.co.uk)

    CI Release npm version

    TypeScript typings which define:

    • The basic JSON objects returned by our APIs (e.g. addresses Address, autocomplete suggestions AddressSuggestion, API key status KeyStatus)
    • The overall shape of JSON responses returned by the API (e.g. postcode lookups PostcodesResponse, address autocomplete queries AddressSuggestionResponse, address search queries AddressQueryResponse)

    Typings are exported to index.d.ts when published to npm. The typings in this repository are defined in lib/index.ts.


    Install package

    npm install --save-dev @ideal-postcodes/api-typings

    Import interfaces and other definitions

    // Import Address type
    import { Address } from "@ideal-postcodes/api-typings";
    let address: Address;


    Benefits of Typings

    Code Completion

    Typings allow IDEs to provide a richer, more productive environment to develop integrations. This includes providing code completions and suggestions.

    Inline Documentation

    Our typings also bear documentation which can be rendered in your IDE as you work.

    Type Checking

    Compile time checks that your library or application appropriately consumes objects and data types returned by our APIs and client libraries

    Non-TypeScript Projects

    Your integration does not have to be exclusively TypeScript driven to benefit from this typings repository.

    Some IDEs (e.g. Visual Studio, Visual Studio Code, Sublime Text) use TypeScript typings to provide inline code completion and documentation for plain JavaScript files.

    It is also possible to develop a partial, robust TypeScript integration against our services and subsequently incorporate it in a larger JavaScript project. TypeScript compiles down to plain JavaScript which can conform to ES3 and later. That output can be exported to other JavaScript projects.


    The testing process involves attempting to compile a test file which assigns API fixtures generated by the API to the interfaces exported by this typings library. The tests will fail to compile if the API fixtures fail to conform to types.
