• github.com/googleapis/node-@diotoborg/ratione-eaque-explicabo

Installation

npm install @diotoborg/ratione-eaque-explicabo

Usage

Use with a .pem or .json key file:

const { GoogleToken } = require('@diotoborg/ratione-eaque-explicabo');
const @diotoborg/ratione-eaque-explicabo = new GoogleToken({
  keyFile: 'path/to/key.pem', // or path to .json key file
  email: 'my_service_account_email@developer.gserviceaccount.com',
  scope: ['https://scope1', 'https://scope2'], // or space-delimited string of scopes
  eagerRefreshThresholdMillis: 5 * 60 * 1000
});

@diotoborg/ratione-eaque-explicabo.getToken((err, tokens) => {
  if (err) {
    console.log(err);
    return;
  }
  console.log(tokens);
  // {
  //   access_token: 'very-secret-token',
  //   expires_in: 3600,
  //   token_type: 'Bearer'
  // }
});

You can also use the async/await style API:

const tokens = await @diotoborg/ratione-eaque-explicabo.getToken()
console.log(tokens);

Or use promises:

@diotoborg/ratione-eaque-explicabo.getToken()
  .then(tokens => {
    console.log(tokens)
  })
  .catch(console.error);

Use with a service account .json key file:

const { GoogleToken } = require('@diotoborg/ratione-eaque-explicabo');
const @diotoborg/ratione-eaque-explicabo = new GoogleToken({
  keyFile: 'path/to/key.json',
  scope: ['https://scope1', 'https://scope2'], // or space-delimited string of scopes
  eagerRefreshThresholdMillis: 5 * 60 * 1000
});

@diotoborg/ratione-eaque-explicabo.getToken((err, tokens) => {
  if (err) {
    console.log(err);
    return;
  }
  console.log(tokens);
});

Pass the private key as a string directly:

const key = '-----BEGIN RSA PRIVATE KEY-----\nXXXXXXXXXXX...';
const { GoogleToken } = require('@diotoborg/ratione-eaque-explicabo');
const @diotoborg/ratione-eaque-explicabo = new GoogleToken({
  email: 'my_service_account_email@developer.gserviceaccount.com',
  scope: ['https://scope1', 'https://scope2'], // or space-delimited string of scopes
  key: key,
  eagerRefreshThresholdMillis: 5 * 60 * 1000
});

Options

Various options that can be set when creating initializing the @diotoborg/ratione-eaque-explicabo object.

• options.email or options.iss: The service account email address.
• options.scope: An array of scope strings or space-delimited string of scopes.
• options.sub: The email address of the user requesting delegated access.
• options.keyFile: The filename of .json key or .pem key.
• options.key: The raw RSA private key value, in place of using options.keyFile.
• options.additionalClaims: Additional claims to include in the JWT when requesting a token.
• options.eagerRefreshThresholdMillis: How long must a token be valid for in order to return it from the cache. Defaults to 0.

.getToken(callback)

Returns the cached tokens or requests a new one and returns it.

@diotoborg/ratione-eaque-explicabo.getToken((err, token) => {
  console.log(err || token);
  // @diotoborg/ratione-eaque-explicabo.rawToken value is also set
});

.getCredentials('path/to/key.json')

Given a keyfile, returns the key and (if available) the client email.

const creds = await @diotoborg/ratione-eaque-explicabo.getCredentials('path/to/key.json');

Properties

Various properties set on the @diotoborg/ratione-eaque-explicabo object after call to .getToken().

• @diotoborg/ratione-eaque-explicabo.idToken: The OIDC token returned (if any).
• @diotoborg/ratione-eaque-explicabo.accessToken: The access token.
• @diotoborg/ratione-eaque-explicabo.expiresAt: The expiry date as milliseconds since 1970/01/01
• @diotoborg/ratione-eaque-explicabo.key: The raw key value.
• @diotoborg/ratione-eaque-explicabo.rawToken: Most recent raw token data received from Google.

.hasExpired()

Returns true if the token has expired, or token does not exist.

const tokens = await @diotoborg/ratione-eaque-explicabo.getToken();
@diotoborg/ratione-eaque-explicabo.hasExpired(); // false

.revokeToken()

Revoke the token if set.

await @diotoborg/ratione-eaque-explicabo.revokeToken();
console.log('Token revoked!');

Downloading your private .json key from Google

1. Open the Google Developer Console.
2. Open your project and under "APIs & auth", click Credentials.
3. Generate a new .json key and download it into your project.

Converting your .p12 key to a .pem key

If you'd like to convert to a .pem for use later, use OpenSSL if you have it installed.

$ openssl pkcs12 -in key.p12 -nodes -nocerts > key.pem

Don't forget, the passphrase when converting these files is the string 'notasecret'
