updating the cache after a mutation about villus

[logaretm]

Hello, sorry for the late reply. At the moment this is outside villus scope since it does not make a relationship between queries and mutations.

However, it is possible for you to build a cache plugin that does this. Something along those lines:

import { definePlugin } from 'villus';

let myCache = {};

const cache = definePlugin({ afterQuery, useResult, operation }) => {
    if (operation.cachePolicy === 'network-only') {
      return;
    }

  if (operation.type === 'mutation') {
    // delete entries from cache
    return;
  }

  // add entries to cache ....
})

Of course, there is a little more involved than that, the main challenge is figuring out which mutations should clear which queries, it is up to you to figure out how such a connection be made. It can be based on a mutation name for example.

I spoke too soon. Having said that, there is a PR #184 that implements cache clearing for mutations that has the same tags as the queries. This is the connection challenge I mentioned.

If that is what you are looking for, then expect it to be out soon.
