Refetch query with new variables at runtime

Hey @stubailo @jbaxleyiii

Relay provides an option in the component called setvariables to change the variables on runtime. Does apollo client support this yet? I see refetch function, but it works like refresh button, which wouldn’t be helpful if someone wants to change the variables and then refetch the query. I think this option could be super useful for things like infinite scroll pagination or filtering - one can set the variable on runtime and fetch the updated data to update the store with new data.

Hi @stubailo I did the same thing for passing variables for this demo app: https://github.com/gauravtiwari/apollo_on_rails/blob/master/app/assets/javascripts/components/posts/show.es6.js#L41, but I think to utilise refetch() with new variables would be much more clear and easy to use.

For example: In infinite scroll pagination, we could just change the number of new records to fetch and page offset and it would fetch the new data.

variables: {
  first: 20,
}

Later for refetching:

this.refetch({
  variables: {first: 40, page: 2}
});

However since we already have the refetch helper method, it would be pretty simple to have that take in a new set of variables.
