javascript - When does vue request data to save global variables?

Question

The business needs to request the dictionary in the background data and save it as a global variable first.
I initially thought that app.vue should be created first, and then the component, so when I put the request data in created in the app, I found that the dictionary data in the component was still in the initial state. I found that their rendering order is that the component is rendered first and then app.vue
How can I get this dictionary in each component? I don’t want to request each component again
