open-next build, OpenNext runs
next build to build the Next.js app, and then transforms the build output to a format that can be deployed to AWS.
OpenNext runs the
build script in your
package.json file. Depending on the lock file found in the app, the corresponding packager manager will be used. Either
npm run build,
yarn build, or
pnpm build will be run. For more on customizing the build command, see overriding the build command.
The build output is then transformed into a format that can be deployed to AWS. The transformed output is generated inside the
.open-next folder within your Next.js app. Files in
assets/ are ready to be uploaded to AWS S3. And the function code is wrapped inside Lambda handlers, ready to be deployed to AWS Lambda or Lambda@Edge.
