Add step templates for Convex backend deployments

[itsmebenwalker]

Summary

This PR adds five new step templates for Convex, a full-stack backend platform built around a serverless TypeScript runtime with a real-time reactive database.

What is Convex?

Convex is a backend-as-a-service platform that replaces a traditional database + API layer with a single, type-safe TypeScript runtime. It provides:

• Reactive queries - clients automatically receive live updates when data changes, without polling or websockets you manage yourself
• Serverless functions - mutations, actions, and queries run in Convex's cloud with ACID transactions and automatic scaling
• Built-in scheduling, file storage, and HTTP actions - a single platform for most backend needs
• Zero-infrastructure deployments - npx convex deploy pushes your schema and functions in seconds

Convex has become a go-to backend for the AI-native development wave. It's deeply integrated with tools like Cursor, Bolt, and v0, and is a favourite among vibe coders - developers who lean on AI assistants to scaffold and ship full-stack apps fast. Convex's fully TypeScript schema, auto-generated types, and instant deployments make it particularly well-suited to AI-assisted workflows where the goal is to go from idea to production with minimal friction. As AI-generated codebases grow in popularity, Convex is increasingly the backend of choice behind them.

Steps added

Step	Purpose
Convex - Deploy	Deploys backend functions and schema to a target deployment (production, preview, or named) via a deploy key
Convex - Set Environment Variables	Pushes KEY=VALUE environment variables from Octopus into the Convex runtime environment
Convex - Export Data	Snapshots deployment data to a local file before a deploy - optionally captured as an Octopus build artifact
Convex - Run Function	Invokes a mutation, action, or query - useful for post-deploy migrations, seed data, or smoke-test queries
Convex - Smoke Test HTTP Action	HTTP health check against a Convex HTTP action endpoint, validating status code and optionally asserting on the response body

All steps require Node.js and npx on the worker. No additional global installs needed - the Convex CLI is invoked via npx.

Other changes

• Supabase - Run Migrations: Fixed the Database Migrations Guide documentation link to point to the correct URL.

Testing

Steps were tested end-to-end using a public test repository: https://github.com/itsmebenwalker/octopus-community-step-temp-convex

Screenshots of each completed deployment step are attached below, along with a raw execution log and screenshots from within the Convex dashboard.

All steps (completed):

Each step output:

• Convex - Set Environment Variables

• Convex - Export Data

• Convex - Deploy

• Convex - Run Function

• Convex - Smoke Test HTTP Action
