One of my data types is called "student."
export interface Student {
name: string,
age: number
}
I am looking to associate this type with a student's information.
data() {
const tommy: Student = {}
return {
tommy,
}
However, I noticed that when I set a string as the value for this data in the mounted hook, no warnings or errors are displayed.
async mounted() {
this.tommy= 'Tommy Smith'
What is the correct way to define custom data types in Vue using TypeScript?
One option is to utilize the Composition API, where you can create an instance of an Object with a specific class in the following manner: const tommy: Student;
Alternatively, if you prefer to stick with the Options API, you can implement type assertions like so:
data() {
return {
tommy: {name: '', age: 0} as Student
}
}
However, there is a potential issue - you mistakenly assigned a string directly to 'tommy', when it should actually be assigned to the 'name' property instead:
async mounted() {
this.tommy.name = 'Tommy Smith'
