Sending an item to the ._map function in Typescript

In the code snippet below, you will find my class that includes a static member called config.

import {Injectable} from '@angular/core';
import {Config} from '../shared/interfaces'

export class GlobalData {

    static config: Config = {
        appName: "",
        line: "",
    }

    constructor(private app: PApplication){
        GlobalData.config.appName = app.getData().Style ? 'P_APP' : 'P_WEB'
        GlobalData.config.line = 'PApp'
    }

}

Here is the interface Config that's utilized in the above code:

export interface Config {
    appName: string
    line: string
}

The goal is to pass the static config object to the following function:

var appConfig = this.appConfig(GlobalData.config);

appConfig = (configVariable: Config) => {
    return _.map(configVariable, function(val, key) {
        return key + "=" + val;
    }).join("&");
}

An error has been encountered during this process:

[ts] Argument of type 'Config' is not assignable to parameter of type 'List<{}> | Dictionary<{}> | NumericDictionary<{}>'. Type 'Config' is not assignable to type 'NumericDictionary<{}>'. Index signature is missing in type 'Config'.

Previously, in Javascript, the config was defined as a global object accessible across different controllers and services.

var config = {appName: "", line: "" }

Answer №1

Here are the specifications for the execute method:

execute<A, B>(
    data: CustomType<A>,
    func: CustomFunction<A, B> | CustomArrowFunction<B> | CustomMatcherFunction<any>,
    context?: any): B[];

execute<A, B>(
    info: CustomData<B>,
    func: CustomProcessor<A, B>,
    context?: any): B[];

It is important to note that the provided input should be of types CustomType<A> or CustomData<B>.
In this scenario, it is required to use CustomData<B>, which has the following definition:

interface CustomData<B> extends ExtendedCollection<B> {
    [key: string]: B;
}

The interface Configuration lacks an index signature causing a compilation error.
To resolve this issue, you can simply cast it to any:

return execute(configurationVariable as any, function(value, key) {
    return key + "=" + value;
}).join("&");

Update

The declarations for execute in the custom library are quite similar:

map<A, B>(
    set: List<A>,
    func?: ListModifier<A, B>
): B[];

map<A extends {}, B>(
    set: Dictionary<A>,
    func?: DictionaryIterator<A, B>
): B[];

map<A extends {}, B>(
    set: NumericDictionary<A>,
    func?: NumericDictionaryIterator<A, B>
): B[];

map<A, B>(
    set: List<A>|Dictionary<A>|NumericDictionary<A>,
    func?: string
): B[];

map<A, C extends {}>(
    set: List<A>|Dictionary<A>|NumericDictionary<A>,
    func?: C
): boolean[];

The Dictionary structure varies slightly:

interface Dictionary<A> {
    [key: string]: A;
}

This leads to a similar complication.
To circumvent using any, consider implementing:

interface Configuration extends Custom.Dictionary<string> {
    applicationName: string
    codeLine: string
}

Subsequently, the syntax will appear as follows:

return map(configurationVariable, function(value, key) {
    return key + "=" + value;
}).join("&");

This code will compile without any errors.
