Description
The method app.provide
is not documented in the API Reference.
There is a mention of it here but the example is incorrect:
The current example given is:
app.provide({
guide: 'Vue 3 Guide'
})
I believe that should be:
app.provide('guide', 'Vue 3 Guide')
A few lines later from: guide
also needs changing to from: 'guide'
.
There is an important distinction between the provide
method, which is part of the Application API, and the provide
option for components. While they're both part of the provide
/inject
mechanism they are distinct ways to provide data.
I've put together an example to demonstrate the difference between the two:

I'm not suggesting using that example in the documentation as I suspect it would be confusing. I just wanted to illustrate the difference between the two here. Notice how data provided via the application is injected into the root component, whereas data provided by the root component is only available in its descendants, not in the root component itself.
I reported these problems previously (#345) but I think there may have been a misunderstanding about what changes needed to be made. In summary:
- The
provide
method needs to be documented in the Application API section of the API Reference. - The example in the migration guide needs to be updated.
