@paketo-buildpacks/nodejs-maintainers can you advise please? My takeaways from that thread are that you probably need to use the Node.js buildpack (rather than Web Servers), and set the |

I doubt any changes are needed in the stack, but I would make sure to use the Full Jammy stack for best results, since it contains the full list of packages we provide. You can do this via the Jammy Full Builder ( |

I’m Balkishun Maurya, I have used (pack build --builder paketobuildpacks/builder-jammy-full) to build a simple Nextjs application which is created by (npx create-next-app@latest my-next-app). but it failed, and these are the logs that i am getting -> Paketo Buildpack for CA Certificates 3.8.3 Executing build process Generating SBOM for /layers/paketo-buildpacks_node-engine/node Configuring build environment Configuring launch environment Paketo Buildpack for NPM Install 1.4.2 Executing build environment install process Configuring build environment Generating SBOM for /layers/paketo-buildpacks_npm-install/build-modules Executing launch environment install process Configuring launch environment Generating SBOM for /layers/paketo-buildpacks_npm-install/launch-modules Paketo Buildpack for Node Run Script 1.0.18 exit status 1 |

I agree with @sophiewigmore. Unless you have used the option to build the site completely statically in Next.js (I'm not a Next.js expert but I believe that is an option not the default), you would need to use the https://github.com/paketo-buildpacks/nodejs, however I would suggest that you use the existing builder - https://github.com/paketo-buildpacks/builder-jammy-full versus specifying build pack. |

We should also likely add a Next.js sample to - https://github.com/paketo-buildpacks/samples/tree/main/nodejs. |

Hello @mhdawson Question: Does the Paketo Buildpacks stack lack support for Next.js applications? |

I search on these errors and they seem to match problems people have been having: It seem to happen if I use some of the default next.js example related to docker so don't think those have anything to do with using a buildpack. The suggestion to resolve seems to be: "build": "NODE_ENV=production next build", with the NODE_ENV=production being the part that fixes it. Not sure how that makes any sense, but seems to be the consensus on how to work around. |

Next.js seems to be a many headed complicated thing. I think the closest use case to building with buildpacks in their examples are the ones using docker. Those include a different configuration from the example shown above. I created a new sample using npx create-next-app --example with-docker myappTrying to build that resulted in the problem that work work around seems to be adding NODE_ENV=production, so I added that to the build command in the package.json Because the examples are to be run with docker they also don't include a start script line in the package.json so I added: "start": "node /workspace/.next/standalone/server.js"I derived that from how the application would have been started when the docker container was started. with that the package.json looked like {
"private": true,
"scripts": {
"dev": "next dev",
"build": "NODE_ENV=production next build",
"start": "node /workspace/.next/standalone/server.js"
},
"dependencies": {
"next": "latest",
"react": "^18.2.0",
"react-dom": "^18.2.0"
}
}I then built with: pack build testit --builder paketobuildpacks/builder-jammy-fulland ran with docker run -p3000:3000 -it testit /bin/bashand the application ran properly. |

Thank you for your response. @mhdawson, It is working for me. Just one last doubt: can we build the same without making changes to the package.json, like adding a procfile or anything you can suggest. |

@Itsdevashishgupta you might be able to use https://github.com/paketo-buildpacks/node-start#bp_launchpoint to set the name of the script to start instead of adding the start entry to the package.json. Is that what you were looking for? |

@mhdawson Yes, that's exactly what I needed! Thanks for pointing me to the bp_launchpoint. I’ll try it out. I think I should add a sample Next.js app to the Paketo Buildpacks samples with this instruction. Thanks again for the help! |

One of the key differences between the examples using docker is that @Itsdevashishgupta my suggestion is that you start with the docker example and build up your application from that as it seems to work ok with the paketo builder. |

We also had to set I found that I could not create the optimized standalone app when building with paketo buildpacks because the This doesn't mean you can use buildpacks to build nextjs apps, but it does mean the standalone output is essentially ignored. |

@jericop thanks for adding that. I agree that what I suggested "works" but it is not optimal. Due to the way it works it might need a Next specific buildpack to get a fully optimized runtime-image. |

As a frontend developer, I’m really excited about the potential for a separate buildpack specifically for Next.js. This would be incredibly helpful for optimizing runtime images. Your support in making this happen would be greatly appreciated! Thanks! |

Hi everyone,
I’m Devashish Gupta, a developer working on a Next.js app, and I’m interested in containerizing it using Paketo buildpacks. I believe this could be valuable for efficient deployment and scalability.
Objective:
I’m looking to gather insights, best practices, and potential challenges in containerizing a Next.js app using Paketo buildpacks.
Context:
My Next.js app is a portfolio website (github repo: https://github.com/Itsdevashishgupta/raph_www). I need to ensure it’s containerized effectively for different environments.
Discussion Points:
Base Image: is there any changes required in stack
Environment Variables: do i need to provide any other env
Your Progress:
So far, I’ve tried
pack build frontend-app --buildpack paketo-buildpacks/web-servers
--env BP_NODE_RUN_SCRIPTS=build
--env BP_WEB_SERVER=nginx
--env BP_WEB_SERVER_ROOT=.next
but I encountered issue
docker run -it -p 3000:3000 --env PORT=3000 frontend-app
nginx 404 not found
So I’m looking for more detailed guidance.
Question:
What are the best practices for a containerized Next.js app?
Thank you in advance for your input! I’ll compile a summary of the responses and share it with the community.
Best regards,
Devashish Gupta
