Exploring the use of Vue and Typescript - encountering the error message "Property ... is not found in type" twice

In my specific case, I believe the error I am encountering may have a different root cause than the common solutions found for it. Configuration-related issues could be at play.

Here is the code snippet:

export default {
  data() {
    return {
      asyncDataStatus_ready: false,
    };
  },

  methods: {
    asyncDataStatus_fetched():any {
      this.asyncDataStatus_ready = true;
      this.$emit('ready');
    },
  },
};

The errors that arise are:

Property 'asyncDataStatus_ready' does not exist on type '{ asyncDataStatus_fetched(): any; }'. Did you mean 'asyncDataStatus_fetched'?ts(2551)

and

Property '$emit' does not exist on type '{ asyncDataStatus_fetched(): any; }'.ts(2339)

It appears that Typescript mistakenly identifies these as properties of asyncDataStatus_fetched, when they are not. My suspicion is that it could be related to the use of 'this', but I am unsure of alternative approaches to resolve this issue. Perhaps there is a different method for methods to access data in a .ts file compared to a .vue file.

Answer №1

The lexical scope of the variable this is not restricted to the component; rather, it pertains to the function. To address this issue, you can utilize a fat arrow function:

methods: {
    asyncDataStatus_fetched: () => {
}
