On event

[Sunny0218]

Hello, it's me again.How can I on different events like native mqtt? For example：client.on('connect', function () {}).I want to be able to do the corresponding business logic as soon as I connect.

Hi @Sunny0218,

Thanks for your questions. You can try the following code:

mqttHook.registerEvent(
        'on-connect', // mqtt status: on-connect, on-reconnect, on-disconnect, on-connect-fail
        (topic: string, message: string) => {
            console.log('mqtt connected')
        },
        'string_key',
)

Thanks, I was going to try it out. I've always had a question, what does the third parameter "string_key" actually do?

When registering the same topic event in multiple components, you can differentiate them using the "string_key".
For example:

// login.ts
mqttHook.registerEvent(
        'on-connect',
        (topic: string, message: string) => {
            // do something
        },
        'login',
)

// dashboard.ts
mqttHook.registerEvent(
        'on-connect',
        (topic: string, message: string) => {
            // do something
        },
        'dashboard',
)
