Concurrent

How to handle multiple Http request when they are sent simultaneously. There are tow strategies provide by Keq: serial or abort.

.flowControl('serial'[, key])

Wait for previous request finish.

import { request } from 'keq'


await Promise.all([1,2,3].map(async i => {
  await request
    .get('/cat')
    .flowControl('serial', 'cat-request')
}))

TIP

Browser can send up to six HTTP request at the same time, and other requests will wait until the previous completed. serial mod ensures that a key will only occupy one HTTP connection at a time.

.flowControl('abort'[, key])

Abort previous request.

import { request } from "keq"

await Promise.all(
  [1, 2, 3].map(async (i) => {
    await request
      .get("/cat")
      .flowControl("abort", "cat-request")
  })
)

TIP

Terminating useless and time-consuming requests can avoid wasting HTTP connection.
