To support different REST endpoints, you need to write a custom router that can trigger different route handlers for /v1/bitcoin/rates and /v1/bitcoin/rates/:currency. This takes a bit of playing around with regex:

Enter a public GitHub repository URL - for example https://github.com/expressjs/express

Backend: Node.js & Express for file handling and metadata extraction.

Casbin provides an external policy engine if your permission model grows complex enough that a centralized JS function becomes hard to maintain. Open Policy Agent serves the same purpose for multi-service architectures. Node.js and Express.js documentation cover the middleware pattern in detail.

Slack’s Workflow Builder lets you create no-code automations to onboard new contributors without writing custom bot code. For OSS projects with enterprise sponsors, this is a low-effort way to increase retention: our benchmark of 50 OSS Slack workspaces showed that onboarding workflows increased 7-day contributor retention by 38%. You can create a workflow that triggers when a new user joins the Slack workspace, sends them a welcome message with links to your GitHub repo, contributor guidelines, and a poll to select their interests. Unlike Discord’s onboarding, which requires custom bot code, Slack’s Workflow Builder is accessible to non-technical maintainers. Here’s a sample workflow configuration (exported from Slack):

Many REST frameworks also ship with limited security controls enabled by default. Express.js , a minimal web framework, does not include rate limiting or input validation out of the box and relies on middleware for these concerns. Django REST Framework includes throttling features, but they are not enabled by default.

For this guide, you will use the authentication proxy approach with Express. This gives you full control over authentication logic and RBAC. It also integrates well with the Descope MCP Express SDK, which is designed to allow you to easily add MCP specification-compliant authorization to your MCP server. The authentication proxy sits between clients and the MCP server, and validates every request before forwarding it.

Here's a basic example of storing a JWT in a cookie using Express:

What always felt wrong in Express and, to a large extent, Fastify, was this pattern:

In Express and Fastify, the default answer to most backend needs is still:
