Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

⚠️ This library is in beta and subject to change. ⚠️

JavaScript Software Development Kit (SDK) for UBIO

This SDK may be used by a client or an end-user of UBIO, with slightly differing functionality.

Installing

The SDK is provided as both a UMD module and an ES6 module, which are in both cases a single file. This allows the module to be used in most deployment and bundling scenarios (and lack thereof). It may also be used with node (see below).

To install with npm, use:

npm install @ubio/client-library

If you're using snowpack for your client side modules:

npm install @ubio/client-library
npx snowpack

If you want to quickly try out this module you can use unpkg.com (not recommended for production):

import {
    createClientSdk,
    createEndUserSdk
} from 'https://unpkg.com/@ubio/client-library?module';

// ...

You may also use the module as an old fashioned global:

<script src="https://unpkg.com/@ubio/client-library"></script>
<script>
    var endUserSdk = ubioSdk.createEndUserSdk({ /* ... */ });
</script>

You can also use this module with Browserify, webpack, RequireJS... you get the picture.

This library requires fetch and Promise to work. If you need to support older browsers, then you must polyfill these. Since Node doesn't include fetch, you should pass an equivalent function in as an argument:

const { createClientSdk } = require('@ubio/client-library');
const fetch = require('node-fetch');

const clientSdk = createClientSdk({ fetch, /* ... */ });

Clients and End-Users

This library is intended for two use cases. As a client, you have the ability to create jobs. Each time a job is created, we also create an "end-user" entity. This entity has the ability to perform actions on a specific job. The intent is that you create a job on behalf of a customer, and then this library may be used in their browser with end-user authentication to update the job and allow it to progress.

This library provides two interfaces, one for the you (client), and one for your customers (end-users). As a client, you must be the one to create a job on behalf of your client. This library may be used as part of a Node.js service to do that (however, you might also prefer to use the API directly, in which case the code for this client may be useful to you as a reference).

The client flow

Your customer decides to make a purchase! On their behalf, you compose a job and POST it to our API to create it.

// On your server.
const { createClientSdk } = require('@ubio/client-library');
const fetch = require('node-fetch');
const token = process.env.UBIO_CLIENT_TOKEN;
const serviceId = process.env.UBIO_SERVICE_ID;
const clientSdk = createClientSdk({ fetch, token });

async function createJob(input) {
    const job = await clientSdk.createJob({ serviceId, input });
    const endUser = await clientSdk.getJobEndUser(job.id);

    return endUser; // Contains jobId, serviceId, and token fields.
}

After creating the job, you can get the end-user entity using the jobId. The end-user token, the jobId, and the serviceId must be sent back to your customer so that JavaScript in their browser can use these to create an end-user SDK object.

// In the customer browser.
import { createEndUserSdk } from '@ubio/client-library';

// Function is called with an object with inputs when the customer decides to
// make a purchase.
async function onSubmit(input) {
    const res = fetch('/this/goes/to/you/see/above/snippet/', {
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ input }),
        // ...
    });

    if (!res.ok) {
        throw new Error('Unexpected response from your server.');
    }

    const endUser = await res.json();
    const endUserSdk = createEndUserSdk({
        token: endUser.token,
        jobId: endUser.jobId,
        serviceId: endUser.serviceId
    });

    // Track the job. When an event occurs the callback will be called. Errors
    // lead to the callback being called with the "error" event name and an
    // error object as its data argument.
    //
    // When the job reaches a state of "success" or "fail" tracking
    // will stop and this function will resolve. The call to trackJob returns
    // a function which, when called, will manually stop tracking.
    const close = endUserSdk.trackJob(job.id, async (eventName, data) => {
        if (eventName === 'awaitingInput') {
            // ask user for input
            const data = await getInputFromUser();

            await createJobInput(key, data);
        }

        // The 'close' event is emitted only once, and no other events will
        // follow.
        if (eventName === 'close') {
            console.log('done!');
        }
    });
}

Client API

Instantiating

The client API requires a client token.

const sdk = createClientSdk({
    token,   // required
    fetch,   // required in Node
    apiUrl,  // optional, defaults to api.automationcloud.net
    vaultUrl // optional, defaults to vault.automationcloud.net
})

Methods

All methods of the sdk object return a Promise instance except for trackJob.

raw(path, options)

For cases when you need to make requests to our API which are not covered by explicit API methods (this should be rare), you may use the raw method. Underneath its fetch doing the heavy lifting. The path is an API path you wish to make a request to, and options is the same as it is for fetch, but with a few differences:

  • Automatic error handling. When our API responds with a 4xy or 5xy error, this method parses the following body and throws it as an error.
  • Automatic response body parsing. This library parses responses directly into objects. If you need the response object instead, set options.parse to false.
  • Automatic request body stringification. When posting, set options.body with an object, not a string.
  • Automatic search string formatting. When you need to use a query, set the options.query field with an object. There's no need to format this yourself and append it to the path.

getServices()

Get a list of your services.

getService(serviceId)

Get a single service by its ID.

getPreviousJobOutputs(serviceId, inputs, key)

Gets the outputs of previous jobs, optionally filtering by an optional list of inputs and an optional output key.

getJobs(query)

Get a list of your jobs. The query has the following optional fields which may be used to refine the list:

| name | description | default | | ---- | ----------- | ------- | | serviceId | | none | | state| "processing", "awaitingInput", "awaitingTds", "success", or "fail". | none | | category | One of "live" or "test". | none | | limit | The maximum number of jobs to respond with, from 0 to 100. | 100 | | offset | Skip the first n jobs. | 0 | | sort | Use "createdAt" to revere the sort order to ascending. | "-createdAt" |

createJob(fields)

Create a job with the following fields:

| name | required | description | default | | ---- | -------- | ----------- | ------- | | serviceId | true | | | | callbackUrl | false | A callback URL to make a request to when particular events occur. | none | | input | false | A prepopulated set of inputs. | {} | | category | false | "live" or "test" | "live" |

getJob(jobId)

Gets a job.

cancelJob(jobId)

Cancels a job.

resetJob(jobId, fromInputKey, preserveInputs)

Resets a job.

createJobInput(jobId, key, data)

Creates a new input with some data under key.

getJobOutputs(jobId)

Gets the outputs of a job.

getJobOutput(jobId, key)

Gets a particular output of a job.

getJobScreenshots(jobId)

Gets the metadata for all screenshots of a job.

getJobScreenshot(jobId, id)

Gets a screenshot by jobId and id. Resolves to a blob.

getJobScreenshot(path)

The endpointgetJobScreenshots returns metadata for screenshots, and a url field may be found in each. This field can be passed to getJobScreenshot directly. Resolves to a blob.

getMimoLogs(jobId)

Gets the MIMO logs for a job by jobId.

getJobEndUser(jobId)

Gets the end-user entity associated with a job. This entity includes a token you may use to delegate operations on the job to a customer.

getJobEvents(jobId, offset = 0)

Gets the events for a given jobId. Use the offset to skip some jobs (useful when manually polling for new events).

getJobFiles(jobId)

Gets the metadata of the files uploaded for a given job.

getJobFile(jobId, fileId|fileUrl)

Gets the data for a given file as a blob.

getActiveTds(jobId)

Gets the active 3D Secure session for the given job.

trackJob(jobId, callback)

Warning: Subject to change!

Track a job. Returns a function which may be called to stop tracking.

The callback will be called with the event name and a payload. Job event names are:

  • "restart"
  • "success"
  • "fail"
  • "awaitingInput"
  • "createOutput"
  • "tdsStart"
  • "tdsFinish"`

Two special events may also be emitted:

  • "error"
  • "close"

When called with the "error" event name, the second parameter will be an error object. Other events have a second parameter which is a payload. In particular the awaitingInput and createOutput events have payloads containing key field.

The "close" event is always the last event and happens only once. It occurs after certain errors (particularly 4xy request errors), after "success" or "fail" events, or after the function returned by the call to trackJob is called. It will only be emitted once, and will include no payload.

createOtp()

Creates a one time password which may be used to vault a PAN.

end-user API

Instantiating

The end-user API requires an end-user token, a serviceId, and a jobId.

const sdk = createClientSdk({
    token,     // required
    serviceId, // required
    jobId,     // required
    fetch,     // required in Node
    apiUrl,    // optional, defaults to api.automationcloud.net
