Ready state promise wrapper
Api
let PReady = require('p-ready')
let ready = new PReady
ready.then(value => console.log('Done', value)) // Just like promise
ready.resolve(1)
// Ok, chaining is also supported
.reset() // It's about creating a new promise, try to comment this line
.then(value => console.log('Done', value))
.resolve(2)
.then(value => console.log('Done', value))
// See more in index.d.ts
Usage example
let PReady = require('p-ready')
class Transport {
ready = new PReady
connect() {
// Connection simulation
console.log('Connecting')
setTimeout(() => {
this.ready.resolve() // Connected
}, 3000)
}
reconnect() {
this.ready.reset()
this.connect()
}
async send(data) {
await this.ready // Here it is
// or use this.ready.promise for direct access
console.log('The', data, 'was sent, hooray!')
}
}
let transport = new Transport
transport.connect()
let num = 0
setInterval(() => {
// We send data regardless of the connection
transport.send('test ' + num)
num++
}, 1000)
setTimeout(() => {
transport.reconnect() // Suppose we reconnect
}, 3000)
