@sequencemedia/gmail-api

The @sequencemedia/gmail-api package is an async interface to the Gmail API by Google.

• It exports functions for querying and requesting Gmail messages, drafts, and labels
• It must be authorised to do so by a human

Usage

Messages

import getGmail from '@sequencemedia/gmail-api/src/gmail'

import {
  getMessages
} from '@sequencemedia/gmail-api/src/gmail/messages/list'

import {
  getMessage
} from '@sequencemedia/gmail-api/src/gmail/messages'

const gmail = await getGmail()
const messageList = await getMessages(gmail, { max: 100 })
const messages = await Promise.all(messagesList.map((message) => getMessage(gmail, message)))

messages
  .forEach((message) => {
    console.log(message)
  })

Labels and drafts follow the same pattern.

Labels

import getGmail from '@sequencemedia/gmail-api/src/gmail'

import {
  getLabels
} from '@sequencemedia/gmail-api/src/gmail/labels/list'

import {
  getLabel
} from '@sequencemedia/gmail-api/src/gmail/labels'

const gmail = await getGmail()
const labelList = await getLabels(gmail)
const labels = await Promise.all(labelsList.map((label) => getLabel(gmail, label)))

labels
  .forEach((label) => {
    console.log(label)
  })

See also messages and drafts.

Drafts

import getGmail from '@sequencemedia/gmail-api/src/gmail'

import {
  getDrafts
} from '@sequencemedia/gmail-api/src/gmail/drafts/list'

import {
  getDraft
} from '@sequencemedia/gmail-api/src/gmail/drafts'

const gmail = await getGmail()
const draftList = await getDrafts(gmail, { max: 100 })
const drafts = await Promise.all(draftsList.map((draft) => getDraft(gmail, draft)))

drafts
  .forEach((draft) => {
    console.log(draft)
  })

Credentials

You must supply public or internal oAuth 2.0 credentials for an application registered with the Google developer console which has the Gmail API enabled, and a credentials token authorising the application to access a Gmail account you control. (The credentials identify your application. The credentials token confirms that your application is authorised to access your Gmail account.)

Configuration

Credentials and credentials tokens can be supplied either as environment variables or as arguments on the command line.

Environment variables

You can supply paths to files on the file system:

CREDENTIALS_PATH
CREDENTIALS_TOKEN_PATH

Or, you can supply JSON:

CREDENTIALS_JSON
CREDENTIALS_TOKEN_JSON

Credentials and credentials tokens supplied as environment variables containing JSON are never written to the file system.

Command-line arguments

Similarly, you can supply paths to files on the file system:

--credentials-path
--credentials-token-path

Or, you can supply JSON:

--credentials-json
--credentials-token-json

Again, credentials and credentials tokens supplied as command-line arguments containing JSON are never written to the file system.

Precedence

• Command-line arguments supersede environment variables (so if you have supplied both, the command line arguments will be used)
• JSON supersedes paths (so if you have supplied both, the JSON will be used, and nothing will touch the file system)

Privacy Policy

The @sequencemedia/gmail-api package does not store any data from Gmail, nor does it gather usage data.
