Deploy a Strapi app that uses Yarn

Q: How do I change the Yarn install command?

Run ezhst build set --install " ", then ezhst redeploy. Pass an empty string to return to auto-detection.

EasyHost picks Yarn when it finds yarn.lock. There is nothing to configure, and these are the exact commands it runs for Strapi.

What EasyHost runs

Step	Command
Lockfile	`yarn.lock`
Install	`corepack enable yarn && yarn install --frozen-lockfile`
Build	`strapi build`, through your package build script
Start	`scripts.start`, which runs `strapi start`

Scripts run with yarn run <script>. Dev dependencies are available during the build, and the app runs with NODE_ENV=production.

Deploy

Use Postgres rather than SQLite, and set Strapi's secret variables before the first deploy.

npx ezhst projects create my-project --link
npx ezhst apps create my-app
npx ezhst link --project <project-slug> --app <app-slug>
npx ezhst env set APP_KEYS=<a>,<b> API_TOKEN_SALT=<salt> ADMIN_JWT_SECRET=<secret> TRANSFER_TOKEN_SALT=<salt> JWT_SECRET=<secret>
npx ezhst env set DATABASE_CLIENT=postgres DATABASE_URL=<connection string>
npx ezhst env import .env
npx ezhst deploy

Things to watch with Yarn

Set packageManager in package.json to pin your Yarn version. Yarn Berry may need --immutable, which you can set with ezhst build set --install.

Commit yarn.lock. Without any lockfile, EasyHost falls back to npm install. To replace the install step, run ezhst build set --install "<command>".
