Angular firebase Error: The parameter 'result' is missing a specified type and is implicitly assigned the 'any' type

Question

Angular firebase Error: The parameter 'result' is missing a specified type and is implicitly assigned the 'any' type

I have encountered an issue with the code I am working on and both the result and error are throwing errors:

ERROR in src/app/login/phone/phone.component.ts(48,75): error TS7006: Parameter 'result' implicitly has an 'any' type. src/app/login/phone/phone.component.ts(53,14): error TS7006: Parameter 'error' implicitly has an 'any' type.

 verifyLoginCode() {
        this.windowRef.confirmationResult.confirm(this.verificationCode).then(result => {

            this.user = result.user;

          })
          .catch(error => console.log(error, "Incorrect code entered?"));
      }

Any suggestions on how to resolve this issue?

The technologies being used are angularfire2 and angular5.

The root cause of this issue lies in the default configuration of Angular's tsconfig.json, where the noImplicitAny flag is set to true - "noImplicitAny": true,. This setting results in Javascript code being generated, but leads to errors due to the compiler being unable to infer types.

A simple solution is to use then((result: any)

In your comment, you mentioned attempting then((result: String). It seems like what you actually intended was then((result: string), as it is important to note that string and String are distinct entities. While string refers to a Javascript primitive defined with literals such as '' or "", String represents a Javascript object with its own prototype chain.

In future instances where the type is uncertain, one can simply determine it by console logging the type:

.then(result => {
  console.log(typeof result)
})

Additionally, considering that you assign this.user = result.user;, it is evident that result is not a string but rather an instance of some kind of Object.

In your typescript configuration, it is imperative to declare the type of every variable before using it. For instance, in this scenario, the method takes a parameter named "result", but fails to specify its TYPE.

To rectify this issue, update the function as follows:

.then((result: ResultType) => {

Here, ResultType should be replaced with the appropriate type for the result.

Furthermore, in the catch callback, the variable error has not been assigned a type. It is advised to modify (error => to ((error: SomeType) =>.

If you find yourself struggling with the noImplicitAny option in your tsconfig compilerOptions, consider disabling it. While this option enforces explicit typing (which is beneficial in the long run), it may hinder experimentation or learning processes.

For projects related to work or managed by others, such as multiple developers collaborating on a project, it might be best to keep noImplicitAny enabled to maintain code quality standards preferred by the team.
