Plan Your Chrome Extension !

 

What Is A Chrome Extension?

Suppose you’re thirsty and you’re near a McDonalds outlet. So you get in & have a look at the menu and you find two choices :

1. A burger combo including a coke
2. A single coke

Given your purpose is to quench your thirst, the single coke will suffice. So chances are you wouldn’t opt for the excess that you don’t need!

Changing context, coming to the software scenario, you can visualize an app as the combo meal (serving multiple purpose & feature-rich) and the chrome extension, as the single coke (built around specific functionalities to simplify browser experience).

Technically, a chrome extension is a small program built using web technologies like CSS, JS, HTML etc. to modify the browser experience or help with advanced browsing functionality. 

Chrome extension development mostly involves web technologies like HTML, CSS, JavaScript, etc.

 

Potential : What A Chrome Extension Can Do?

Custom chrome extension development targets acing a single task that the browser otherwise doesn’t help with. So how to identify such ‘tasks’?

Ideally, the kind of tasks that can be performed best with a chrome extensions should :

1. Be streamlined i.e. narrowly defined in terms of scope
2. Involve low to medium logical complexity
3. Include one or a set of features that strictly contribute to a common goal

Now back to the point, what all can you achieve with a custom chrome extension development?

Looking To Develop A Chrome Extension? Start With Answering A Few Of My Questions Below. 

1. What particular business problem will the chrome extension automate? 
2. How will the chrome extension make a difference to your user’s life? 
3. What will your business gain with the help of the chrome extension and what do you have to lose if it didn’t exist? 
4. Are there sufficient other chrome extensions similar to yours?

This question answer round is important because understanding the purpose behind developing a chrome extension will keep you aligned to your goals and help keep you focused. And always remember, the best idea is the one that solves the problem that you personally face on a daily basis. 

So, if your extension solves a particular problem and is pretty unique, then, you might just go ahead and develop one. Assuming you are not a developer yourself, you would first need to actually hire chrome extension developers to do the job for you. 

Chrome extensions are basically written in HTML, CSS, and JavaScript. So, these three technologies should be at the top of your mind  when you are hiring a chrome extension developer.

Start with the most daunting task - Create a detailed business spec. Whether the engagement is for a year or for 2 weeks, a BRD (Business Requirement Doc) is important. While it’s really convenient to bind a contract with the first available chrome extension development company, it’s not advisable. It’s better that you do your due diligence so that you make sure that you are going to be delivered with the chrome extension that you envisioned. 

 

Take A Look At A Few Tips That You Should Keep In Mind Before Developing Chrome Extension. 

 

[1] Have An Idea About The Chrome Environment

Before the development starts, make sure you have minimal knowledge of the chrome architecture. I'm not advising to go read all the docs, but a vague idea of how it works overall would be good for you. 

 

[2] Make Sure It Doesn’t Increase Browser Memory Consumption

One very important thing to keep in mind is that though chrome extensions are useful, they can sometimes happen in a way that they increase browser memory consumption, thus making the browser slow. 

Even before the first line of code is written, make sure your developer uses the same version of the javascript library for the extensions that are used by the site. 

It is also recommended to use vanilla Javascript where there is no requirement of loading complex libraries. Also, one can minimize using libraries that are already present on the page. 

 

[3] Support Google Accounts

If your chrome extension requires user login, make it a point to support Google accounts. This is because when a user is purchasing or installing the chrome extension from the chrome web store, odds are that the user is already logged in the google account at this point. So, reducing the no. of logins improves the user’s experience. 

[4] Have An Idea Where User Credentials Are Stored

So, you can store data either as window.localStorage OR chrome.storage.local. We at BinaryFolks, highly recommend chrome.storage.local. This is because window.localStorage is HTML5 storage. Unless that is running in the background, the data can be set into storage for a specific domain. So, there is no way data can be shared across different web pages unless you use localStorage in the background page. 

Chrome extension stats

chrome.storage.local, on the other hand, is designed for Chrome Extensions to store data in a more central location. This way each extension gets its own storage. With unlimited Storage permission, it can hold arbitrarily large amounts of data. Also, if extensions sync is enabled, it can be automatically synced between signed-in Chrome instances. 

Also, according to Chrome’s basic guidelines, user data should be stored for a minimum of 30 days even after they cancel the subscription or uninstall the chrome extension. There might be a lot of reasons for users unsubscribing or uninstalling or even if their exit was intentional, they might sometimes come back. 

 

 

[5] Follow Basic Guidelines While Publishing Chrome Extension To Store

Last but not least, once the chrome extension development is completed, be wise to choose your primary app category as that determines where your app will appear in the web store. Each category is further organized into logical groups and you will be displayed under the group heading in the filtered category. 

Also, list keywords to improve search relevance, or to influence future versions of the category list. All chrome extensions go through an automated review process and then almost immediately published in the Chrome store, in most cases. There may be some instances in which a manual review will be required before the app is published.

 

 

How To Build A Chrome Extension - Simplified, Step-By-Step

Chrome Extension Development - Step 2 : Find a development team with a portfolio showcasing similar projects

A recipe doesn’t guarantee a good dish unless there’s a pro chef waiting to take it up.

Similarly a great chrome extension development plan handed over to the wrong development partner is a certain recipe to disaster.

Chrome Extension Development - Step 4 : Design An intuitive UI 

Slip in the shoes of your customers. Know as a customer, what element will be best noticed at what position. Competitor’s analysis will get you halfway there, your intuition would help with the rest. Regardless what purpose it’s built to serve, make sure to keep the UI simple and clean.

 

Chrome Extension Development - Step 5 : On your mark. Get. Set. Develop!

The cream of the chrome extension development process undoubtedly comes out of the development phase, which is the 4th and the most important step. The two major aspect of development are -

Choosing the right development partner in the first place is your gateway to the best of both!

 

Chrome Extension Development - Step 6 :  Test. Fix Bugs. Repeat!

Development phase isn’t complete without a repeating feedback and fix loop closely following it. So,testing is the obvious next & the final step of the chrome extension development process.
