What are some ways to condense this Angular/TS code for improved performance and readability?

I am in need of assistance with refactoring a method called getBaseUrl(). This method assigns a specified string value to this.baseURL based on the input serviceType.

getBaseUrl(serviceType: string, network?: string) {
    // Method logic to determine baseURL
}

I would like the refactored method to meet the following criteria:

  1. Have a concise implementation
  2. Optimized for performance
  3. Enhanced readability

Your guidance and support in achieving this goal would be greatly appreciated. Thank you in advance.

Answer №1

Here are the steps to improve your code structure, readability, and performance:

  1. To enhance code organization, create a separate file for your serviceTypeMap variable called service-type.enum.ts. Define your array in this file as shown below:

Enums in TypeScript allow developers to define a set of named constants, making it easier to document intent or create distinct cases.

export enum ServiceTypeMap  = {
    PROXY_13541: ["pipInventory"],
    PROXY_13561: [
      "pipChangeManager",
      "pubChangeManagerdbw",
      "pubChangeManager",
      "pubChangeManager alert",
      "pipChangeManagerBulkvalidate"
    ],
    <!-- more enum values here -->
  };

  1. Next, let's define the getBaseUrl() method as follows:

/* Import your enum */

public getBaseUrl(serviceType: string, network?: string) {
  this.network = network;

  for (const [baseURL, neededServiceTypes] of Object.entries(ServiceTypeMap)) {
    if (neededServiceTypes.includes(serviceType)) {
      this.baseURL = `/${baseURL}/`;
      break;
    }
  }

  this.options = this.getOptions();
}

Thank you!
