@hubspot/serverless-dev-runtime

A serverless function development runtime that can be used to test CMS serverless functions. This is intended for use with the CMS CLI.

⚠️ This is a BETA release that uses some HubSpot features that are not available to all customer accounts. Please refer to the HubSpot Developer Beta Terms ⚠️

Getting started

For more information on using these tools, see Local Development Tooling: Getting Started.

Usage

CLI Command (recommended)

Using the CLI to run serverless functions locally, requires installing @hubspot/cli. Once installed, to test your functions run…

hs functions test <folder.functions>

Importing

It also is possible to use the runtime inside your own tooling. To start the server, the start method can be imported from the @hubspot/serverless-dev-runtime package and run with settings like so...

const { start } = require('@hubspot/serverless-dev-runtime');

start({
  accountId: <portalId/accountId>,                                                  // default: 123456
  contact: <booleanValueToSpecifyIfContactDataShouldBePassedToServerlessFunction>,  // default: true
  path: <pathToLocalDotFunctionsFolder>,                                            // required
  port: <customPortToRunServerOn>                                                   // default: 5432
});

Mocked Data

Some of the data that is passed to the serverless function context is mocked. Specifically the contact and limits properties. It is possible to modify the mocked data by setting values for specific variables within a .env file within the .functions folder.

The variables used to modify the data are:

HUBSPOT_LIMITS_TIME_REMAINING       // default: 600000
HUBSPOT_LIMITS_EXECUTIONS_REMAINING // default: 60
HUBSPOT_CONTACT_VID                 // default: 123
HUBSPOT_CONTACT_IS_LOGGED_IN        // default: false
HUBSPOT_CONTACT_LIST_MEMBERSHIPS    // default: []

Usage example .env:

HUBSPOT_LIMITS_TIME_REMAINING=1000
HUBSPOT_LIMITS_EXECUTIONS_REMAINING=2
HUBSPOT_CONTACT_VID=456
HUBSPOT_CONTACT_IS_LOGGED_IN=true
HUBSPOT_CONTACT_LIST_MEMBERSHIPS="some, memberships"
