Create a websocket server with a jsonlines file
npm install @epimodev/json-websocketjson-websocket is a cli which makes possible to create a WebSocket with a jsonlines file (more info about jsonlines here: http://jsonlines.org/).
It's like json-server, but it creates a WebSocket instead of a REST api.
Initially I made this project to help people have the same experience as PandaScore live api without waiting for a live match.
But it will help us also create WebSocket with fake data for our development environment.
We can also imagine with this tool a way to reproduce some bugs related to realtime.
``shinstall locally in your project
yarn add @epimodev/json-websocketinstall globally
yarn global add @epimodev/json-websocket
$3
sh
start a WebSocket server which sends events stored in
live_frames.jsonl (jsonl is the extension for jsonlines files)
json-websocket live_frames.jsonlstart a WebSocket server binded to 8080 port
json-websocket live_frames.jsonl --port 8080start a WebSocket server with timestamp stored in
current_timestamp field of each line
this is usefull to reproduct exactly the same intervals as the recorded WebSocket
json-websocket live_frames.jsonl --timer_field current_timestampstart a WebSocket server with an interval of 2 seconds between each event sent
json-websocket live_frames.jsonl --interval 2

sh
