Remote Work Tips 2021

A dedicated workspace

First thing first, you must first create a workspace for yourself. It might seem unnecessary for many of you but even with your laptop, create at least a small workspace for yourself. Space where only your work stuff is kept, where the natural light just comes right and gives you the motivation to work hard. You can even create a replica of what your office desk looked like.

Schedule

You are at your home, it can be tricky. It might be difficult for you to not binge watch that show and read the comics available right at your arm's length. Or listen to your brother's rowdy story from school and help your dad repair that board. But you need you to schedule it all.

Keep your work schedule tight and always try to work with any other distractions.

Breaks

No matter how tempting it gets to finish that one project, just take a break. As much as your work is important, your mental health is to.. taking a break-even for a short walk or just to have a chat with your family can help you release stress and start over.

Exercise

You have been sitting all day long. It can be a problem if you don't do some physical activity. Stretch your legs and exercise at least 20 minutes a day. It can be very beneficial for you and your physical health. Sitting for a very long time can give you more problems than you think. Diabetics, heart diseases, and even cancer can be a risk if you don't avoid sitting for long hours. So don't be lazy and get yourself moving.

Colleagues

Since you can't see your colleagues working, work might not be motivating. Connect with them on calls or chats. Discuss each other's progress. Basically, overcommunicate which you wouldn't normally do in the office. The environment makes all the difference.

Family time

Apart from all this what matters the most is your family. Take some time out and interact with your family, chat with them, and engage with some activities. Make a call to your loved ones if you stay away from them but it is important you remain in a connection with them.

I hope these remote work tips were helpful for you. Comment below if you want to know about more such working tips. 

VueJS Material Design Frameworks

Vuetify

Vuetify is the most popular vuejs material design framework. It’s there in the market since 2014 and offers a bunch of great features.

It’s an open-source framework, however, the Vuetify team also provides business and enterprise support.

You can also find some premium themes on their website which will dramatically boost your development time with a ready-made high performant theme.

The best part about Vuetify is that it supports automatic treeshaking. That means it will only import the components you need and the final bundle will include only those. This feature leads to a much smaller bundle size and boosts website loading time.

One thing that makes Vuetify more promising is that they publish updates weekly.

So if you are looking for a vuejs material design framework with better community support, frequent releases, and small in size then go with Vuetify.

Quasar

Quasar is also an impressive vuejs material design framework. It’s not only limited to be used on websites. You can also build desktop apps, mobile apps, browser extensions, and PWA with it.

Quasar is totally an open-source framework under MIT license. There is no option for enterprise support at the moment.

It provides various add-on features like HTML, CSS & JS minification, cache busting, ES6 transpiling. Also, it provides automatic treeshaking.

Quasar team is also very active and their release cadence is bi-weekly.

If you are looking for a framework to build apps with VueJS for multiple platforms then Quasar is the best solution.

Vue Material

The last framework of our list is Vue Material. It’s a lightweight alternate but the list of components is much less as compared to others.

This framework is sponsored by Creative Time and you can find premium themes based on this framework, made by them.

The release frequency is not found anywhere on the website however it’s an active repository on Github. The last push was 19 days ago from today so you can expect monthly updates.

VueMaterial also has an option for custom development which is backed by an IT company.

You can go with VueMaterial if you are looking for a lightweight alternate.

I will update the list if I found any new VueJS based material design frameworks. So make sure to create an account to get an update in your inbox when we update the list.

AdonisJS vs ExpressJS

AdonisJS is developed by Harminder Virk. It’s inspired by frameworks like Ruby on Rails and Laravel.

ExpressJS is developed by TJ Holowaychuk in 2010. It was later acquired by StrongLoop.

ExpressJS vs AdonisJS – Architechture

ExpressJS is a minimalist web framework. It gives you the freedom and flexibility to work with any database, ORM or folder structure.

AdonisJS on the other hand is an MVC framework. MVC stands for Model, Views, and Controllers.

Every AdonisJS project ships with a set of folders and files. We need to understand the folder structure first in order to work with it.

However, for a scalable web application, a good project structure matters. So AdonisJS makes sure you get it right.

ExpressJS vs AdonisJS – Routing

A robust routing system helps us to develop an application quickly. Both of the frameworks have a decent routing system.

That can work with static and dynamic, both types of routes.

Express router is pretty basic but it does the job.

Adonis gives us the option to bind routes to controllers, group routes, create REST resources with them.

ExpressJS vs AdonisJS – ORM

ORM stands for Object Relational Mapping. Evry modern full-featured framework ships with its own ORM.

ORM is very helpful while working with database queries, tables, table relationships.

AdonisJS has its own ORM called Lucid. It’s a very powerful tool that can quickly build queries, create and handle migrations, can run seeds and factories, and also provides data modeling.

Express does not ship with an ORM. However, there are multiple 3rd party ORM available for NodeJS which can be used with Express.

Sequelize is a really good ORM for NodeJS and can work with Express.

ExpressJS vs AdonisJS – Authentication

Adonis 5 ships with its own authentication system that can save your time in production.

It supports 3 different types of authentication – Web sessions, API tokens, and basic HTTP authentication as well.

Express JS does not have an inbuilt authentication system. There are tools like Okta which can be integrated with ExpressJS to handle authentication.

AdonisJS vs ExpressJS – Templating

AdonisJS ships with its own templating engine called Edge. You can use loops, add conditions, create layouts, create components, and a few more.

Edge also provides a tool to inspect and debug templates with it.

Express does not have any templating engine out of the box. However, you can create your own templating engine with the app.engine(ext, callback)method.

Creating your own templating engine may sound interesting but it’s a time-consuming process.

Express has supports for many external templating engines. Here you can find the full list.

AdonisJS vs ExpressJS – Sending mails

You can use the official adonisjs/mail package to send emails from your application. It uses NodeMailer internally to send emails.

Also, it has inbuilt support for SMTP, AWS SES, Mailgun, and Sparkpost.

We can also use Nodemailer with Express. However, with Express we need the set the drivers manually.

AdonisJS vs ExpressJS – Performance

Finally the most crucial question – is Express JS faster than Adonis JS?

In short, the answer is no. AdonisJS 5 has added a lot of amazing features and improvements.

The HTTP server is one of those. It’s almost as fast as Fastify.

You can find more details regarding the benchmark here.

Finally, I have shared 7 major differences between AdonisJS and ExpressJS. Both are amazing frameworks but make sure to choose the one according to your needs.
