I have a mutation in my graphQL schema that I want to resolve manually.

I came across the **cypherMutation** function in the [docs](https://grandstack.io/docs/neo4j-graphql-js-api.html#cyphermutationparams-context-resolveinfo) but I find the description a little lacking without an example.

Can someone provide a simple example using the cypherMutation within a resolver to connect to a neo4j database and resove a graphQL request?

Hi @Banhawy - the idea of the `cypherMutation` (and `cypherQuery`) function is to just generate the Cypher query (and Cypher parameters) for a specific GraphQL request without handling the call to the database. A use case for when to use `cypherMutation` instead of the auto-generated mutations would be if you want to have some additional authorization logic before sending the query to the database.

You can see some examples of using `cypherMutation` in the tests for neo4j-graphql-js: [neo4j-graphql-js/cypherTestHelpers.js at master · neo4j-graphql/neo4j-graphql-js · GitHub](https://github.com/neo4j-graphql/neo4j-graphql-js/blob/master/test/helpers/cypherTestHelpers.js#L56-L82)

Oh I initially thought I had to define the Cypher query both in the GraphQL schema and in the resolver, this makes much more sense.

Thanks @lyonwj!

This question approaches one that I have which is how to query the database from the api side of the application. For example, if I wanted to query graphql in place of Users.findOne() within a passport strategy like in the authentication/authorization blog code examples
