Foxx JWT Session Storage

const jwtStorage = require('@arangodb/foxx/sessions/storages/jwt');

The JWT session storage converts sessions to and from JSON Web Tokens .

Examples

// Pass in a secure secret from the Foxx configuration
const secret = module.context.configuration.jwtSecret;
const sessions = sessionsMiddleware({
  storage: jwtStorage(secret),
  transport: 'header'
});
module.context.use(sessions);

Creating a storage

jwtStorage(options): Storage

Creates a Storage that can be used in the sessions middleware.

Note: while the “none” algorithm (i.e. no signature) is supported this dummy algorithm provides no security and allows clients to make arbitrary modifications to the payload and should not be used unless you are certain you specifically need it.

Arguments

• options: Object

  An object with the following properties:

  • algorithm: string (Default: "HS512")

    The algorithm to use for signing the token.

    Supported values:

    • "HS256" (HMAC-SHA256)
    • "HS384" (HMAC-SHA384)
    • "HS512" (HMAC-SHA512)
    • "none" (no signature)

  • secret: string

    The secret to use for signing the token.

    This field is forbidden when using the “none” algorithm but required otherwise.

  • ttl: number (Default: 3600)

    The maximum lifetime of the token in seconds. You may want to keep this short as a new token is generated on every request allowing clients to refresh tokens automatically.

  • verify: boolean (Default: true)

    If set to false, the signature is not verified but still generated (unless using the “none” algorithm).

  • maxExp: number (Default: Infinity)

    Largest value that is accepted in an incoming JWT exp (expiration) field.

If a string is passed instead of an options object, it is interpreted as the secret option.
