Proxymise: Chainable Promise Proxy

Proxymise

Chainable Promise Proxy.

Lightweight ES6 Proxy for Promises with no additional dependencies. Proxymise allows for method and property chaining without need for intermediate then() or await for cleaner and simpler code.

Use

npm i proxymise
const proxymise = require('proxymise');

// Instead of thens
foo.then(value => value.bar())
  .then(value => value.baz())
  .then(value => value.qux)
  .then(value => console.log(value));

// Instead of awaits
const value1 = await foo;
const value2 = await value1.bar();
const value3 = await value2.baz();
const value4 = await value3.qux;
console.log(value4);

// Use proxymise
const value = await proxymise(foo).bar().baz().qux;
console.log(value);

Practical Examples

Performance

Proxymised benchmark with 10000 iterations is practically as performant as the non-proxymised one.

node test/benchmark.js 
with proxymise: 3907.582ms
without proxymise: 3762.375ms

What's the Link Between Web Automation and Web Proxies?

Web automation and web scraping are quite popular among people out there. That’s mainly because people tend to use web scraping and other similar automation technologies to grab information they want from the internet. The internet can be considered as one of the biggest sources of information. If we can use that wisely, we will be able to scrape lots of important facts. However, it is important for us to use appropriate methodologies to get the most out of web scraping. That’s where proxies come into play.

How Can Proxies Help You With Web Scraping?

When you are scraping the internet, you will have to go through lots of information available out there. Going through all the information is never an easy thing to do. You will have to deal with numerous struggles while you are going through the information available. Even if you can use tools to automate the task and overcome struggles, you will still have to invest a lot of time in it.

When you are using proxies, you will be able to crawl through multiple websites faster. This is a reliable method to go ahead with web crawling as well and there is no need to worry too much about the results that you are getting out of it.

Another great thing about proxies is that they will provide you with the chance to mimic that you are from different geographical locations around the world. While keeping that in mind, you will be able to proceed with using the proxy, where you can submit requests that are from different geographical regions. If you are keen to find geographically related information from the internet, you should be using this method. For example, numerous retailers and business owners tend to use this method in order to get a better understanding of local competition and the local customer base that they have.

If you want to try out the benefits that come along with web automation, you can use a free web proxy. You will be able to start experiencing all the amazing benefits that come along with it. Along with that, you will even receive the motivation to take your automation campaigns to the next level.
