Release Notes

firebase/firebase-functions

v3.11.0

Compare Source

• Adds support for vpcConnector and vpcConnectorEgressSettings fields in functions.runWith(). Must be used in conjunction with firebase-tools v8.9.0 or higher. Thanks @​pcboy! (#​752)

v3.10.0

Compare Source

• Adds support for functions failure policies (#​482)

v3.9.1

Compare Source

• Updates firebase-admin dependency to support ^9.0.0 in addition to ^8.0.0. Note that firebase-admin no longer supports Node.js 8.x as of 9.0.0.
• Fixes logging of unexpected errors in https.onCall() functions.

v3.9.0

Compare Source

• Updates HTTP callable functions to use structured logging for Node 10+ environments.
• Adds type hints for new Cloud Functions regions asia-northeast3, asia-south1, and asia-southeast2.
• Updates type definition of https.onRequest to allow for promises (async functions).

v3.8.0

Compare Source

• Fixes error when last argument to logger methods is null. (#​716)
• Adds eight new available regions:
  • us-west2
  • us-west3
  • us-west4
  • europe-west6
  • asia-northeast2
  • northamerica-northeast1
  • southamerica-east1
  • australia-southeast1
• No longer throw errors for unrecognized regions (deploy will error instead).
• Fixes error where snap.ref in database functions did not work when using the Emulator Suite (#​726)

v3.7.0

Compare Source

• Adds functions.logger SDK to enable structured logging in the Node.js 10 runtime. For example:

  const functions = require('firebase-functions');
  
  functions.logger.debug('example log with structured data', {
    uid: user.uid,
    authorized: true,
  });

• Adds a special require that mimics Node.js 8 runtime logging in Node.js 10 and later runtimes:

  require('firebase-functions/lib/logger/compat');

  In newer runtimes, requiring this will emit text logs with multi-line support and appropriate severity. In the Node.js 8 runtime, the compat module has no effect.

• Fixes https.onRequest type signature to allow Promises for async functions.

v3.6.2

Compare Source

• Pin @types/express version to 4.17.3 to fix type definition issue (Issue #​685).
• Firestore onCreate, onUpdate, and onDelete now receive a QueryDocumentSnapshot instead of DocumentSnapshot, which guarantees that data is not undefined (Issue #​659).
• Modify return type of DataSnapshot.forEach to boolean | void match firebase-admin SDK.

Compare Source

• Update TypeScript dependency to v.3.8 to fix build issues (Issue #​667)

  functions.runWith({
    maxInstances: 10
