A poller to swim easily to success status!

Install

$ yarn add @ovh-ux/ng-ovh-swimming-poll

Usage

import angular from 'angular';
import ngOvhSwimmingPoll from '@ovh-ux/ng-ovh-swimming-poll';

angular.module('myApp', [ngOvhSwimmingPoll]);

Features

• Understand standard Task states
• Customizable states (with object or function)
• Can share the result between different scopes
• Can retry when error rejection is triggered (with retryMaxAttempts, retryCountAttempts and retryTimeoutDelay task options)

With OVH standard task

The poller can manage return from OVH Task standard. This library understand OVH status and return promise when the task is finished.

function createPoller(Poller) {
  const url = '/task/42';
  Poller.poll(
    url,
    null, // params
    {
      namespace: 'a_namespace',
      method: 'get',
      scope: $scope.$id,
    },
  ).then(
    (result) => {
      console.log('result contains http response if task status is successful');
    },
    (result) => {
      console.log(
        'result contains http response if task status is in error state',
      );
    },
    (result) => {
      console.log(
        'result contains http response if task status is in pending state',
      );
    },
  );
}

With custom validation rules

When you want to poll another thing that an OVH task, you had to define your custom validation rules.

function createPoller(Poller) {
  const url = '/ip/192.168.1.1/status';
  Poller.poll(
    url,
    {
      headers: 'demo',
    },
    {
      namespace: 'a_namespace',
      method: 'get',
      scope: $scope.$id,
      successRule: {
        status: 'yeah_it_works',
        billingStatus(elem) {
          return elem.billing.status === 'nietMeerGeld';
        },
      },
      errorRule: {
        status: 'oh_damned',
        billingStatus(elem) {
          return elem.billing.status === 'verdom';
        },
      },
    },
  ).then(
    (result) => {
      console.log('result contains http response if status is yeah_it_works');
    },
    (result) => {
      console.log('result contains http response if status is oh_damned');
    },
    (result) => {
      console.log(
        'result contains http response if status is not oh_damned and not yeah_it_works',
      );
    },
  );
}

With custom validations rules, on a listing

You can do a polling on listing request. In this case:

• promise will return success when all elements of the list are successful.
• promise will return error when one element or more in the list is in error state and all other are in success state
• else, promise will send a notify with the http response

function createPoller(Poller) {
  const url = '/ip';
  Poller.poll(
    url,
    {
      headers: 'demo',
    },
    {
      namespace: 'a_namespace',
      method: 'get',
      scope: $scope.$id,
      successRule: {
        status: 'yeah_it_works',
        billingStatus(elem) {
          return elem.billing.status === 'nietMeerGeld';
        },
      },
      errorRule: {
        status: 'oh_damned',
        billingStatus(elem) {
          return elem.billing.status === 'verdom';
        },
      },
    },
  ).then(
    (result) => {
      console.log(
        'result contains http response if all statuses are yeah_it_works',
      );
    },
    (result) => {
      console.log(
        'result contains http response if one or more status is oh_damned and other yeah_it_works',
      );
    },
    (result) => {
      console.log(
        'result contains http response if one or more status is not a finalized status',
      );
    },
  );
}

With time interval

You can specify the interval as a fix value or a function

function createPoller(Poller) {
  const url = '/task/42';
  Poller.poll(
    url,
    null, // params
    {
      namespace: 'a_namespace',
      method: 'get',
      scope: $scope.$id,
      interval(iteration) {
        return 10 * Math.exp(iteration);
      },
    },
  ).then(
    (result) => {
      console.log('result contains http response if task status is successful');
    },
    (result) => {
      console.log(
        'result contains http response if task status is in error state',
      );
    },
    (result) => {
      console.log(
        'result contains http response if task status is in pending state',
      );
    },
  );
}
