GraphQL Cheat Sheet

An alternative approach to RESTful APIs
Clients issue queries/mutations to read and update data
Clients can fetch only the entity fields that are required
GraphQL query syntax can express complex entity relations => nested objects
Mitigates the explosion of RESTful endpoints in scenarios where many different representations of an entity are needed
Graphiql is a query execution UI, also provides good documentation

	const driveUploadPath = 'https://www.googleapis.com/upload/drive/v3/files';

	// 'id' is driveId - unique file id on google drive
	// 'version' is driveVersion - version of file on google drive
	// 'name' name of the file on google drive
	// 'appProperties' keep the custom `ifid` field
	const fileFields = 'id,version,name,appProperties';
