vue-simple-websocket

A simple native reconnecting websocket client for Vue.js.

__If you like or use this project, please consider supporting my work. Thanks! 🙏🏼__

Usage instructions

These instructions are for usage with Vue 3.x.

For usage information with Vue 2.x, see here. The older version will not receive updates.

Install

``
npm install vue-simple-websocket --save
`

Basic Usage

In the Vue app entry file main.js
`js
import VueSimpleWebsocket from "vue-simple-websocket";

const app = createApp(App);
// Configure the server to connect to and reconnection parameters
// Here, we enable reconnection and retry every 5s if connection is lost
app.use(VueSimpleWebsocket, "wss://echo.websocket.org", {
reconnectEnabled: true,
reconnectInterval: 5000
});
app.mount("#app");
`

Usage in Vue components

The plugin adds a $socketClient to your app.

In your components, you can handle websocket events by setting them up in the created or mounted hook.
- onOpen — event when socket is connected
- onMessage — event when socket receives a message
- onClose — event when socket is closed
- onError — event when socket is closed abnormally

If the connection is broken, the event handlers will continue to work when reconnection succeeds.

`js
// Component.vue
export default {
name: 'Component',
//
created () {
this.$socketClient.onOpen = () => {
console.log('socket connected')
}
this.$socketClient.onMessage = msg => {
console.log(JSON.parse(msg.data))
}
this.$socketClient.onClose = () => {
console.log('socket closed')
}
this.$socketClient.onError = () => {
console.log('socket error')
}
}
}
`

Sending messages

send()
This calls the websocket send method and can be used for sending string data.

`js
let data = {
type: 'message',
text: 'hello there'
}
this.$socketClient.send(JSON.stringify(data))
`

sendObj()

A convenience method sendObj is available for sending javascript objects:

`js
let data = {
type: 'message',
text: 'hello there'
}
this.$socketClient.sendObj(data)
`

This is also a personal project to learn how to build and publish packages on npm. I have deliberately started with a repository from the ground up (instead of going with a template starter) in order to get my hands dirty setting up various components such as babel, rollup as well as tests using jest`. As you can probably tell, there is a fair bit of work that needs to be done in order to make this package robust and maintainable.

I'd be super grateful to get pointers from folks who have more experience building and maintaining packages on npm. :)
