Remix - Deployment

You wrote this Dockerfile for Remix:

FROM node:18
COPY . /app
WORKDIR /app
CMD ["npm", "run", "start"]

But the app crashes on start with missing dependencies error. What is the problem?

AWORKDIR should come before COPY

BYou forgot to run npm install to install dependencies

CCMD syntax is incorrect

DNode version 18 is not supported by Remix

Step-by-Step Solution

Solution:

Step 1: Check Dockerfile steps for dependency install
The Dockerfile copies files but never runs npm install, so dependencies are missing.
Step 2: Confirm impact on app start
Without dependencies installed, the app crashes on start due to missing packages.
Final Answer:
You forgot to run npm install to install dependencies -> Option B
Quick Check:
Missing npm install causes crash = A [OK]

Quick Trick: Always run npm install before starting app in Docker [OK]
