Which Node version does the lab need?

[kOaDT]

npx create-oss-store fails, or the app crashes on start. What Node version is supported?

[kOaDT]

Node 20 or newer. Check with node --version.

Node 20 and 22 (both LTS) are the two the lab is built and tested against — the Docker image ships node:20-alpine, and better-sqlite3 and Cypress both need 20+. Node 18 will fail somewhere between npm install and the first request, usually while compiling the native SQLite binding.

If you are on an older version, the cleanest fix is nvm:

nvm install --lts && nvm use --lts
npx create-oss-store my-ctf-lab

If you would rather not touch your Node setup at all, use Docker instead:

docker run -p 3000:3000 leogra/oss-oopssec-store

If it still fails after that, post the full output of node --version, npm --version and the error itself. Native module build errors are usually a missing toolchain, not a Node problem.
