Tips for preventing the [Vue warn]: Injection "xxxx" not found error

My current setup involves utilizing the inject/provide pattern within the nuxt composition-api. An example of this is Component A injecting a function provided by Component B, which is the parent of Component A, as illustrated below.

//Component B 
const test = () => {}
provide('test', test)
//Component A 
const test = inject<Function>('test')

However, when I attempt to use Component A without Component B, a warning message is displayed in the console. Although I understand the purpose of the warning, it is unnecessary in this particular scenario since the ''test'' function is not needed. Is there a way to circumvent this warning?

[Vue warn]: Injection "test" not found

Answer №1

To prevent the error message, make sure to set a default value (the second parameter in inject()):

const example = inject<Function>('example', () => {})
