# graphql-prisma-select-fields

This is a small helper library that helps you not over-fetch while using GraphQL with Prisma.

### Example

```js

import gqlSelectConverter from 'graphql-prisma-select-fields'

const app = fastify()

app.register(mercurius, {

  ...,

})

app.ready().then(() => {

  app.graphql.addHook('preExecution', async (schema, document, context) => {

    context['selectFields'] = gqlSelectConverter(document)

    ...

  })

})

// Models

export const ModelQuery = extendType({

  type: 'Query',

  definition(t) {

    t.nonNull.list.field('models', {

      type: Model,

      resolve(source, args, ctx) {

        return ctx.prisma.account.findMany(ctx.selectFields.Model)

      }

    })

  },

})

```

Note that this is a really small library. You can customize it as you wish to fit to your codebase.
