How to Resolve the Gigwage Client ESLint Error in NestJS Easily

When working with the Gigwage client in a NestJS application, you may run into a frustrating ESLint error that can impede your development process. This issue is specifically related to how TypeScript infers types, and the error message you might receive is:

TS2742: The inferred type of 'findAll' cannot be named without a reference to '@gigwage/client/node_modules/axios'. This is likely not portable. A type annotation is necessary.

This error typically arises when TypeScript struggles to determine the return type of your function, which can lead to complications if not addressed properly. Let's break down the steps to resolve this issue effectively.

Understanding the Problem

The error you're facing, TS2742, essentially suggests that TypeScript requires a more explicit type definition in your function. This requirement usually indicates that the inferred return type might not be portable, meaning others may struggle to use your function without appropriate context or resources. In essence, TypeScript wants you to explicitly declare what type will be returned from your findAll function.

Solution to the ESLint Error

To tackle this error, you need to provide an explicit type annotation for your findAll function. This is accomplished by indicating that the function will return a Promise containing an AxiosResponse. Below are the steps to implement this fix:

Step 1: Import the AxiosResponse Type

Before you define your function, ensure you're importing the AxiosResponse type from the axios package. This type is essential for the annotations you'll be providing. Your import statement should look like this:

Step 2: Annotate the Function’s Return Type

Next, you need to modify your findAll function to explicitly specify its return type. Here’s how your function signature should appear:

Breakdown of the Return Type Annotation:

Promise: Indicates that the function is asynchronous and will return a promise.

AxiosResponse: This encapsulates the structure of the response you expect to receive from the Gigwage API. The generic parameters specify that the data will contain an object with a contractors property, which is an array of Contractor instances.

Conclusion

By following the steps outlined above, you can effectively eliminate the TS2742 ESLint error when using the Gigwage client with NestJS. Providing explicit type annotations not only resolves the immediate issue but also enhances the maintainability and readability of your code.

Additional Tips

Regularly update your dependencies to ensure compatibility and access to the latest features and fixes.

Utilize TypeScript's type-checking capabilities to catch potential errors early in your development process.

With this knowledge, you're well-equipped to handle similar type-related issues in the future. Happy coding!
