Snapshot Plugin

The snapshot plugin allows applying snapshot for development usage.

The snapshot plugin writes the responses of your remote data source to your file system and then uses it instead of re-fetching it every time. It’s also helpful because you can easily manipulate your data manually and see how your API mesh responds.

To get started with this plugin, install it:

npm i @graphql-mesh/plugin-snapshot

How to use?

Add the following configuration to your Mesh config file:

plugins:
  - snapshot:
      if: "process.env.NODE_ENV != 'production'"
      apply:
        - https://my-remote-api.com/*
      outputDir: __snapshots__

The following snapshot will work if you are in a development environment (see the if command).

To modify your snapshots and change the responses, go to __snapshots__ and modify the responses under those files.
