Fusebit OAuth Connector

This is the Fusebit OAuth Connector, a simple way to to implement a multi-tenant integration between your application and a third-party API authenticated with OAuth, on top of the Fusebit platform.

Getting started

Assuming you are a subscriber of Fusebit, you would start by using the fuse CLI to deploy a Fusebit OAuth Connector Manager to your subscription:

``
git clone git@github.com:fusebit/oauth-connector.git
cd oauth-connector
fuse function deploy --boundary managers oauth-connector-manager -d ./fusebit
`

Soon enough you will be writing code of your integration logic. Get in touch at Fusebit for further instructions or to learn more.

Organization

- lib/connector contains the core Fusebit OAuth Connector logic that manages authentication to an API protected with OAuth access tokens in a multi-tenant system.
- lib/manager contains the Fusebit OAuth Connector Manager logic which supports the install/uninstall/configure operations for the connector.
- lib/manager/template contains a template of a Fusebit Function that exposes the Fusebit OAuth Connector interface. As a developer, you will be spending most of your time focusing on adding your integration logic to VendorOAuthConnector.js.
- fusebit contains a template of a Fusebit Function that exposes the Fusebit OAuth Connector Manager interface.

Running tests

Here are a few things you need to know before running tests:

- You must have access to a Fusebit subscription.
- You must have the Fusebit CLI installed.
- You must have a Fusebit CLI profile configured with an account ID and subscription ID, and sufficient permissions to manage all functions and all storage on that subscription.
- The test will create and remove functions in randomly named boundary in the subscription.
- The test will create and remove storage objects in randomly named storage ID in the subscription.

To run the tests, set the FUSE_PROFILE environment variable to the Fusebit CLI profile name to use:

`
FUSE_PROFILE={profile-name} npm test
`

In case of a failure, you can get useful, verbose diagnostic information with:

`
debug=1 FUSE_PROFILE={profile-name} npm test
``
