Node.js REST API Example
This example shows how to implement a simple REST API using Node.js and Docker. The API has five endpoints that all return a simple response in JSON.
- GET /
- GET /:id
- POST /
- PUT /
- DELETE /
Build
docker build -t nodejs-rest-api-example .
Run
Run in default port 4000:
docker run -p 4000:4000 -d nodejs-rest-api-example
Run in custom port, e.g., 8080:
docker run -e PORT=8080 -p 8080:8080 -d nodejs-rest-api-example
