Shared env Object

If you want to provide and shared global object in form of a known interface, you can provide env to the op definition. env object will default extend the HttpServerShim and extend the given interface on top.

import { httpOp, httpReturn, as } from 'ts-basis/nodejs'

interface MyInterface {
    someSharedKeyValueMap: {
        [key: string]: any
    }
}

export const myApiFunction = httpOp(
    {
        env: as<MyInterface>(),
        params: {},
        returns: httpReturn<{ data: string }>(),
    },
    async (op, env) => {
        // env is (HttpServerShim & MyInterface) type
        // shared key-value map can have data shared amongst the APIs
        env.someSharedKeyValueMap['key'] = 'test'

        return op.returnJson({ data: 'Hello World!' })
    },
)
