Echo TCP server

Utility server for debugging TCP message communication by echo or by replying pre-defined response.

Run

node server.js

How it works

1. Start the Echo TCP Server
2. Connect and submit data to the server
3. The server will echo the data submitted or the predefined response.

Add predefined response

Requirement:

• Configure an .env file with an AUTOREPLY setting.
• Add your predefined response as a text file in your project.

Environment configuration

• PORT: (Number) Server port for listening
• HOST: (String) Server Host or IP for listening

AUTOREPLY settings

Value: JSON string

It is a key/value pair where the key represent the beginning of the received data and the value is the file system path where to load the response.

For example:

AUTOREPLY=`{
	"GET /example/endpointA": "responses/endpointA.txt",
	"POST /example/endpointA": "responses/endpointA-post.txt"
}`
