How to pass data to a view in react?

Question

JavaScript

It is necessary to make a task manager on react. There is a component - a container of tasks, which should send different requests to the server to obtain data about the tasks that need to be displayed. How, when requesting a page with a task manager, in addition to the page itself, also give a link to which the container should point?
PS The only way I know of to pass information to a component is an attribute of that component. But you can set the attribute only on the client, since the page is rendered dynamically on this very client.
