Core Features & Use Cases

Environment Variable Check: Verifies the presence and configuration of essential environment variables against a .env.example file.
Build and Type Checking: Executes pnpm typecheck and pnpm lint within the shipkit directory to ensure code quality.
Vercel Deployment Verification: Checks the status of Vercel deployments and tests connectivity to the deployed site.
Demo Site Access Test: Confirms accessibility of the landing page and key sub-pages of the demo site.

Quick Start

FAQPage Schema

How do I verify environment variables before deploying a web application?▼

Pre-launch verification automates environment variable checks by comparing your configuration against a `.env.example` file to identify missing variables and provide resolution guidance before deployment.

What does a preflight build check include for ShipKit projects?▼

A preflight build check executes `pnpm typecheck` and `pnpm lint` within the `shipkit` directory to validate code quality and identify type errors before you proceed with a release.

Can I run specific deployment checks individually instead of a full suite?▼

Yes, you can run granular checks using arguments like `--check-env`, `--build`, and `--deploy` to target specific validation areas, or execute `--all` to run the comprehensive pre-launch suite.

How do I test Vercel deployment status and demo site accessibility?▼

Vercel deployment verification checks the deployment status and tests connectivity to the deployed site, while the demo site access test confirms the landing page and key sub-pages are accessible.

Why does my Vercel deployment fail despite passing local build checks?▼

Vercel deployment failures can occur due to missing environment variables. Running a preflight check verifies environment configurations against `.env.example` to identify missing variables before deployment.
