GraphQL Cheat Sheet

Overview

• 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

Upload Files to Google Drive using Javascript

News

At October 11, 2019, I published a Javascript library to to run the resumable upload for Google Drive. When this is used, the large file can be uploaded. You can also use this js library.

Description

This is a sample script for uploading files to Google Drive using Javascript. The files are uploaded by Drive API v3. gapi.client.drive.files.create() can create an empty file on Google Drive. But it cannot directly upload files including contents. I think that this might not be able to upload files and metadata with the multipart/related, although this might be resolved by the future update. So now, as one of workarounds, I use using XMLHttpRequest.

• This sample uses gapi.
• Before you use this, please enable Drive API at API console and carr
