The following worked for me, there are two parts:
01) app.js
02) Google and OAuth2 setup
app.js
var nodemailer = require("nodemailer");
var transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: {
type: 'OAuth2',
user: local_settings.my_gmail_username,
clientId: local_settings.my_oauth_client_id,
clientSecret: local_settings.my_oauth_client_secret,
refreshToken: local_settings.my_oauth_refresh_token,
accessToken: local_settings.my_oauth_access_token
}
});
var mail = {
from: "John Smith <me@mydomain.com>",
to: "user@userdomain.com",
subject: "Registration successful",
text: "You successfully registered an account at www.mydomain.com",
html: "<p>You successfully registered an account at www.mydomain.com</p>"
}
transporter.sendMail(mail, function(err, info) {
if (err) {
console.log(err);
} else {
// see https://nodemailer.com/usage
console.log("info.messageId: " + info.messageId);
console.log("info.envelope: " + info.envelope);
console.log("info.accepted: " + info.accepted);
console.log("info.rejected: " + info.rejected);
console.log("info.pending: " + info.pending);
console.log("info.response: " + info.response);
}
transporter.close();
});
Google and OAuth Setup
The code above requires the following setup:
01) Go to https://console.developers.google.com
02) If you don't have a project, you will be prompted to create one

03) Click on Create Project
04) Click on Create
![enter image description here]()
05) Enter a Project Name and click Create
![enter image description here]()
06) Select the Gmail API
![enter image description here]()
07) Click on Enable
![enter image description here]()
08) Click on Create Credentials
![enter image description here]()
09) Enter the required settings
![enter image description here]()
10) Give the OAuth client a name and ensure you add https://developers.google.com/oauthplayground as a redirect URI in order to generate the refresh and access tokens later
![enter image description here]()
11) Define the consent screen settings
![enter image description here]()
12) Click I'll do this later and Done
![enter image description here]()
13) Click on the Edit icon, to view your Client ID and Client Secret
![enter image description here]()
14) To generate access and refresh tokens, go to https://developers.google.com/oauthplayground
15) Click on the cog icon in the top right, check Use your own OAuth credentials and enter Client ID and Client Secret
![enter image description here]()
16) In the left column, select Gmail API v1 and click Authorise APIs
![enter image description here]()
17) If you are signed into multiple accounts, when prompted select the relevant account
![enter image description here]()
18) Click Allow
![enter image description here]()
19) Click Exchange authorisation code for tokens
![enter image description here]()
I'm not sure why there is a count down on the access token, but hopefully the message at the bottom of the screen means that the token won't expire.
