async function exeCuteMe(){
  let inbox = new Inbox('credentials.json');
  await inbox.authenticateAccount(); // logs user in
  
  let messages = await inbox.getLatestMessages();

  console.log("my inbox messages", JSON.stringify(messages,null,4));
  
  // Note: give  https://github.com/ismail-codinglab/gmail-inbox a star if it saved you time!
}

Getting started

Get gmail API credentials

To work with the gmail API you need to get the credentials from the google cloud console.

Step 1 Follow the google instructions to Create a client ID and client secret.

Step 2 Go to https://console.cloud.google.com/apis/credentials and download the OAuth2 credentials file, as shown in the image below.

Google cloud platform

Your credentials file (commmonly named clientsecret*.json), should look similar to image below

credentials file example

Note: make sure you selected 'other' as project and that the redirect_uris contains something like "urn:ietf:wg:oauth:2.0:oob"

Step 3 Copy the example code in #example and execute the script

Step 4 The application will prompt to visit the authorization url. Navigate to the url, select your email and copy the code as shown in the image below. Copy image url

Note: The authorization token will only be valid for 6 months, after 6 months a renewal is required.

Step 5 Done! You're good to go, you should be able to see your inbox messages, enjoy coding! :)

API

Since the code is typed in TypeScript I will just include the self-documented interfaces :)

Available methods

interface InboxMethods {
  /**
   * Logs the user in. 
   * If there is no authenticated user then a instruction will pop-up and an input is required
   */
  authenticateAccount(): Promise<void>;
  /**
   * Finds messages based on the searchQuery
   * Can be typed or plain text as you can be used to in the gmail search-bar
   */
  findMessages(searchQuery: SearchQuery| string);
  /**
   * Gets all the labels. Default ones and custom ones.
   */
  getAllLabels(): Promise<Label[]>;
  /**
   * Gets the latest messages
   */
  getLatestMessages(): Promise<Message[]>;
  /**
   * Waits until a message is received. 
   * Handy for testing if the 'welcome' or 'verify email' email is being send within a time limit e.g. 60seconds
   */
  waitTillMessage(
    searchQuery: SearchQuery | string,
    shouldLogEvents: boolean,
    timeTillNextCallInSeconds: number,
    maxWaitTimeInSeconds: number
  ): Promise<Message[]>;
}

Inbox.findMessages(searchQuery: SearchQuery) / Inbox.waitTillMessage(searchQuery: SearchQuery, ...)

Both findMessages and waitTillMessage support the same searchquery

export type MessageIsType = 'read' | 'unread' | 'snoozed' | 'starred' | 'important';

export interface MessageDateType {
  date: Date;
  precision: "year" | "day" | "milliseconds";
}

export type UnixTimestamp = number; // this alias for number gives you a better autocomplete suggestion

export interface SearchQuery {
  /**
   * Search for one or multiple potential subjects
   */
  subject?: string | string[];
  message?: string;
  mustContainText?: string | string[];
  from?: string | string[];
  to?: string | string[];
  cc?: string;
  bcc?: string;
  /**
   * In which label the message should be
   */
  labels?: string[];
  has?: 'attachment' | 'drive' | 'document' | 'spreadsheet' | 'youtube' | 'presentation';
  /**
   * Some possible extensions to search with, if not use "filename" property with your extension. e.g. filename: "png"
   * Note: The filenames containing the extension will also be returned. E.g. 'filenameExtension:"pdf" will also return 'not-a-pdf.jpg'
   */
  filenameExtension?: 'pdf' | 'ppt' | 'doc' | 'docx' | 'zip' | 'rar';
  /**
   * you can search like filename: "pdf" or filename:"salary.pdf"
   */
  filename?: string;
  /**
   * What status the message is in
   */
  is?: MessageIsType | MessageIsType[];

  /**
   * same as 'newer'
   */
  after?: MessageDateType | UnixTimestamp,
  /**
   * same as 'older'
   */
  before?: MessageDateType | UnixTimestamp,

  /**
   * same as 'before'
   */
  older?: MessageDateType | UnixTimestamp,
  /**
   * same as 'after'
   */
  newer?: MessageDateType | UnixTimestamp,

  olderThan?: {
    /**
     * Must be higher than 0
     */
    amount: number;
    period: 'day' | 'month' | 'year';
  };
  newerThan?: {
    /**
     * Must be higher than 0
     */
    amount: number;
    period: 'day' | 'month' | 'year';
  };
  
  maxResults?: number;

  category: 'primary' | 'social' | 'promotions' | 'updates' | 'forums' | 'reservations' | 'purchases';
