* will be created that you can query with (id: ID!).
*
* @remarks
* This is a helper function to create a node with an associated way to fetch it.
* Nodes get assigned a unique ID which is derived from `base64Encode(nameOfType + node[key || 'id'])`.
* The fields property can be used to rename properties, type them and even create custom resolve functions
* for computed properties or transformations.
* Optionally when the output-type has no `id` property you can use the `key` option to specify a different
* property used to uniquely identify the node.
*
* @example
* ```ts
* export const LaunchNode = node<OutputType, typeof key>({
* name: 'Launch',
* key: 'flight_number',
* async load(ids) {
* // get and return the data
* }
* fields: (t) => ({
* // we tell our node that it can find the name on a different property named mission_name and to
* // expose it as a string.

* details: t.exposeString('details', { nullable: true }),
* image: t.field({
