Little function to call mutate against multiple cached keys of SWR

SWR Mutate Many

Little function to call mutate against multiple cached keys of SWR.

Usage

Install it

$ yarn add swr swr-mutate-many

Import it and use it

import { mutateMany } from 'swr-mutate-many';

mutateMany('key-*', 'New Value', false);

Now mutateMany will change the value of any key matching the glob key-* (any starting with key-) to have the value "New Value" and it won't trigger a revalidation.

API

mutateMany follow a similar API as SWR mutate.

1. The key to mutate, in our case it could be:

• A string supporting globs to match the key, useful for simple logic
• A function which will receive the key and should return true/false if it matches, useful for complex logic

2. The new value to use, a promise whose resolved value will be used or a function receiving the current value
3. If the keys should be revalidated, in our case it could be:

• A boolean, as in mutate, useful if you want all to revalidate or not
• A function, which will receive the key and return a boolean, useful for complext logic
