Nunjucks vs React: What are the differences?

Introduction

In this article, we will discuss the key differences between Nunjucks and React. Nunjucks is a template engine for JavaScript that allows for server-side rendering, while React is a JavaScript library for building user interfaces that focuses primarily on client-side rendering.

  1. Template Engine vs. UI Library: The main difference between Nunjucks and React lies in their primary use cases. Nunjucks is a template engine that focuses on rendering HTML on the server side. It provides features like template inheritance, macros, and filters, making it suitable for generating dynamic HTML content. On the other hand, React is a UI library that is primarily used for building interactive and reusable user interfaces on the client side. It allows for component-based development, virtual DOM manipulation, and efficient rendering of UI updates.

  2. Server-Side vs. Client-Side Rendering: Another significant difference between Nunjucks and React is the way they handle rendering. Nunjucks excels at server-side rendering, where templates are pre-compiled and rendered on the server before being sent to the client. This approach can help improve initial page load times and SEO. In contrast, React focuses on client-side rendering, where components are rendered on the client's browser. This allows for more dynamic and interactive user interfaces, but it requires the client to have JavaScript enabled.

  3. Syntax and Templating Language: Nunjucks and React also differ in their syntax and templating languages. Nunjucks uses a flexible and powerful syntax inspired by jinja2, which allows for template inheritance, logic statements, loops, and other advanced features. It provides a rich set of built-in filters and macros for manipulating data within templates. React, on the other hand, uses JSX (a syntax extension for JavaScript), which combines HTML-like syntax with JavaScript code to define components. JSX allows for embedding JavaScript expressions within templates, making it easier to build dynamic UIs.

  4. Extensibility and Ecosystem: In terms of extensibility and ecosystem, React has a more vibrant and extensive community. It has a large number of third-party libraries and tools available for building complex UI components, managing state, and handling data flow. React also provides official tooling, such as React Developer Tools and Create React App, which streamline development workflows. Nunjucks, while not as widely adopted as React, offers plugins and extensions that allow for customizing its functionality to suit specific use cases.

  5. Learning Curve and Development Experience: When it comes to the learning curve and development experience, React might have a steeper learning curve compared to Nunjucks. React requires developers to understand concepts like component-based architecture, lifecycle methods, and state management. In contrast, Nunjucks follows a more traditional template-based approach, which can be easier to grasp for developers familiar with web templating languages like Jinja2 or Mustache. However, React's extensive documentation and active community can help developers overcome the initial hurdles and provide a more comprehensive development experience.

  6. Integration with JavaScript Ecosystem: Nunjucks and React also differ in their integration with the wider JavaScript ecosystem. Nunjucks can be seamlessly integrated with Node.js and other server-side JavaScript frameworks, allowing for shared code and easy server-side rendering. React, being a client-side library, integrates well with front-end frameworks and tools like Redux, Webpack, and Babel to build scalable and performant applications. React can also be used with server-side rendering frameworks like Next.js and Gatsby to combine the benefits of both server-side and client-side rendering.

In Summary, Nunjucks is a server-side template engine primarily used for rendering dynamic HTML content, while React is a client-side UI library used for building interactive user interfaces. Nunjucks focuses on server-side rendering with a flexible templating language, while React excels at client-side rendering with JSX syntax. React has a larger ecosystem and a steeper learning curve, while Nunjucks is more straightforward and integrates well with server-side JavaScript frameworks.

What is the best MVC stack to build mobile-friendly, light-weight, and fast single-page application with Spring Boot as back-end (Java)? Is Bootstrap still required to front-end layer these days?

The idea is to host on-premise initially with the potential to move to the cloud. Which combo would have minimal developer ramp-up time and low long-term maintenance costs (BAU support)?

React might be a good option if you're considering a mobile app for the future, because of react native. Although, Vue.js has the easiest learning curve and offers a better developer ramp-up time. Vue.js is great to build SPAs, very clean and organized and you won't have a lot of long-term maintenance problems (like AngularJS, for example). Bootstrap can still be used, but with flexbox there's no need anymore.

I recommend React because of less memory occupant compare to Angular, but this will depend on your organisation flexibility. When you use React you need to import different libraries as per your need. On the other side angular is a complete framework.

Performance-wise I vote for react js as it loads up quickly and lighter on the mobile. You can make good PWA with SSR as well.

If you are new to all three react will be a good choice considering, react-native will be useful if you want to build cross platform mobile application today or tomorrow. If you are talking about bootstrap styling framework than it's a choice you can style ur components by ur self or use bootstrap 4.0 framework. The complete stack mentioned above is platform agnostic u can run it anywhere you want be it cloud or on-premise.

Simple datepickers are cumbersome. For such a simple data input, I feel like it takes far too much effort. Ideally, the native input[type="date"] would just work like it does on FF and Chrome, but Safari and Edge don't handle it properly. So I'm left either having a diverging experience based on the browser or I need to choose a library to implement a datepicker since users aren't good at inputing formatted strings.

For React alone there are tons of examples to use https://reactjsexample.com/tag/date/. And then of course there's the bootstrap datepicker (https://bootstrap-datepicker.readthedocs.io/en/latest/), jQueryUI calendar picker, https://github.com/flatpickr/flatpickr, and many more.

How do you recommend going about handling date and time inputs? And then there's always moment.js, but I've observed some users getting stuck when presented with a blank text field. I'm curious to hear what's worked well for people...

In my view, the upside of React is you're likely to find more existing, robust design systems (e.g. sets of components containing anything from buttons to datepickers) in the React ecosystem than Vue. UI frameworks aside, momentjs comes in when you want operate on the date(times) you get back from whatever datepicker you choose (e.g. date formatting, date match).

I find using Vue.js to be easier (more concise / less boilerplate) and more intuitive than writing React. However, there are a lot more readily available React components that I can just plug into my projects. I'm debating whether to use Vue.js or React for an upcoming project that I'm going to use to help teach a friend how to build an interactive frontend. Which would you recommend I use?

I've used both Vue.js and React and I would stick with React. I know that Vue.js seems easier to write and its much faster to pick up however as you mentioned above React has way more ready made components you can just plugin, and the community for React is very big.

It might be a bit more of a steep learning curve for your friend to learn React over Vue.js but I think in the long run its the better option.

I chose to use Vue.js a few years ago mainly for the easy learning curve. I have no experience with React, so I won't make any comparison here. Regarding available components, I never felt locked in because of Vue when looking for components. It happens that a component I wish to use is not available as a Vue component (and nobody published any Vue wrapper for it), but in such cases I was able to quickly hack a Vue wrapper component. In the end I don't think a decision to choose one framework over another should be made solely because of the number of components available. (And not all components in either framework is maintained, bug free, documented or easy to use)

I would also go with React. The learning curve can be a little more difficult but as soon as you got the concepts it's really easy to create things. As everybody has mentioned the React community is huge and it keeps growing, anything you may need for your project there are super high probabilities that you will find it.

React is great, Vue.js is also great. But I'm personally using React, because React is changing the way I look at how JavaScript should be. This is a really big plus for me. Vue is good, but it's just another alternative. Also, too many big companies are using React, that means you can trust it for big projects.

I'd have to concur that I'd advise React. In addition to the reasons mentioned, the developer pool is significantly larger (and also slightly more expensive) for React. In time, engineering costs will even out as more and more teams adopt it. The community support is fantastic, and the available components significant.

Would start with Vue especially if you want to progress more quickly and don't want/need to spend time learning React just for the sake of it. You can always pick up React later if necessary. I would caution about using "more readily available React components" just because they exist.

Both have their pro's and con's; however to agree what has been mentioned here before; Using Vue.js will be easier as it's learning curve isn't steep; plus learning Vue.js will teach you fundamentals which (in a sense) can be applied to React as well. Community support for React is indeed very big, but Vue.js is also still growing. Component wise, I wouldn't worry to much about that, writing your own components is also a good tool for learning a language.

Anything that interacts with the Internet, websites, applications, etc., while it may be more complex to build, will be easier to maintain in the long run. React offers more flexibility, a much larger support base for knowledge and opinion, and is just as stable asVue.

To make the best comparison in my opinion, think of React as the Android OS and Vue more like iOS. While Vue may be advantageous in some cases, it is limited by constricting parameters. On the other hand, while React may be more complex and incorporate more open-source/third-party constructs, it is supported by over 50,000 npm packages and allows for the use of JSX. Which I might add, once learned, becomes second nature to employ and offers more flexibility.

Having developed in both Vue.js and React, I agree with your assessment of Vue. It does feel light and easier to understand and therefore learn. Seeing that Vue has some genetic roots with React, I would say start your friend out on Vue. If they need to learn React later, that should give them a good foundation. If you have a Pluralsight subscription, look for my course on Vue.js and feel free to use the demo project as a starting point.

It all depends. Vue.js is smaller, and from what I saw (benchmarks) faster. It's also slightly more intuitive and easier to grasp. React is more popular, and the adoption rate is much higher.

Again, it all depends.

If I may, my personal choice would perhaps be either React or Svelte.

We did a comparison between React, Vue and Angular and while found each capable of supporting our needs, we ended up using VueJS because of its ease of use, the ability to use templates, large and growing community and good documentation. After developing on it for a around 4 months we re-evaluated and agreed that we had made the right choice and continue to migrate our products/platform to it.

As others have stated there are more canned components available for React, but your observation about it's complexity is an important one. There are architectural aspects of Vue.js that lead to cleaner more concise solutions. As React apps get bigger they become a little unwieldy. Depending on your requirements you need to weigh those competing concerns. Our team is using React, but I am beginning to question that choice as time goes on. Another consideration is that Vue.js is becoming more mature as we speak. Also as others join the project, react developers should be productive in Vue.js within days. Just my 2 cents...

VueJS hands down. Which components do you need? Have a look at Vuetify, mature project, plenty of components ready to plug and play. If on the other side you need more customization, have a look at tailwindcss. VueJS is much cleaner and IMO will overtake React soon. It's simply a better React.

It was easier to find people who've worked on React than Vue. Angular did not have this problem, but seemed way too bloated compared to React. Angular also brings in restrictions working within their MVC framework. React on the other hand only handles the view/rendering part and rest of the control is left to the developers. React has a very active community, support and has lots of ready-to-use plugins/libraries available.

It is a very versatile library that provides great development speed. Although, with a bad organization, maintaining projects can be a disaster. With a good architecture, this does not happen.

Angular is obviously powerful and robust. I do not rule it out for any future application, in fact with the arrival of micro frontends and cross-functional teams I think it could be useful. However, if I have to build a stack from scratch again, I'm left with react.

Working on a new SaaS web/mobile app and ended up with React as our choice of Frontend JavaScript framework for SPA web version with React Native for iOS, Android, Windows clients.

The key takeaways:

  • Both frameworks can do the job quite well for us. This might be true for the majority of utility web apps being built out there as well, so there was no "wrong" decision here.

  • Vue is often cited as easier to learn and code on. But only in case your engineers never worked with either Vue or React and start learning them from scratch. In our case, we knew we'll be hiring engineers who already have experience in the framework we'll select - so it was not a big argument for Vue.

  • We're building our engineering team in Ukraine and realised we have 3(!) times more engineers with React experience on the market than having Vue experience.

  • Mobile - React Native, despite being a different framework, still shares a lot with React and it's just easier for React developers to start using React Native in days.

The strongest points for our decision:

  • React community is larger, means more/faster answers to your questions and existing components.

  • Way more experienced React engineers on the market.

  • React + React Native is a great combo if you're building web and mobile clients of the same app.

I used React not just because it is more popular than Angular. But the declarative and composition it gives out of the box is fascinating and React.js is just a very small UI library and you can build anything on top of it.

Composing components is the strongest asset of React for me as it can breakdown your application into smaller pieces which makes it easy to reuse and scale.

Svelte is everything a developer could ever want for flexible, scalable frontend development.

Our whole Vue.js frontend stack (incl. SSR) consists of the following tools:

  • Nuxt.js consisting of Vue CLI, Vue Router, vuex, Webpack and Sass (Bundler for HTML5, CSS 3), Babel (Transpiler for JavaScript),
  • Vue Styleguidist as our style guide and pool of developed Vue.js components
  • Vuetify as Material Component Framework (for fast app development)
  • TypeScript as programming language
  • Apollo / GraphQL (incl. GraphiQL) for data access layer (https://apollo.vuejs.org/)
  • ESLint, TSLint and Prettier for coding style and code analyzes
  • Jest as testing framework
  • Google Fonts and Font Awesome for typography and icon toolkit
  • NativeScript-Vue for mobile development

The main reason we have chosen Vue.js over React and AngularJS is related to the following artifacts:

  • Empowered HTML. Vue.js has many similar approaches with Angular. This helps to optimize HTML blocks handling with the use of different components.
  • Detailed documentation. Vue.js has very good documentation which can fasten learning curve for developers.
  • Adaptability. It provides a rapid switching period from other frameworks. It has similarities with Angular and React in terms of design and architecture.
  • Awesome integration. Vue.js can be used for both building single-page applications and more difficult web interfaces of apps. Smaller interactive parts can be easily integrated into the existing infrastructure with no negative effect on the entire system.
  • Large scaling. Vue.js can help to develop pretty large reusable templates.
  • Tiny size. Vue.js weights around 20KB keeping its speed and flexibility. It allows reaching much better performance in comparison to other frameworks.

When I started TipMe, I thought about using React frontend. At the end, plain, simple jQuery won.

I had to build this iteration of the site fast and by using jQuery I could keep using Django as a full stack development tool. One important point is Django form (combined with Django Bootstrap3) means that I don't have to reinvent form rendering again, which will be the case with React.

Over time, more interactivity seeped into the site and React components start making its way into the codebase.

I now wish the site is built using React so that I could add more user friendly interfaces easier (no more fuddling with server states) but I would still say jQuery helped me get past those early days.

React has by far and away been our most important library choice throughout the history of Sellpy. It is a library that offers great flexibility supported by a really strong core.

React was a very contentious decision among the Meteor community. We started off with Blazejs, which itself was based off of Handlebars. We liked the HTML-like syntax of Blaze and how nurses, doctors, and other clinicians could become familiar with it. However, the code wasn't very reusable and it was neither modular nor composeable nor testable, and became a major headache to maintain. React solves the problems of composeability and reusability and testing isolation, at the price of having worked the problem backwards and having wound up with a quirky syntax that runs within Javascript that looks similar to HTML but isn't. Nonetheless, React is quickly become a classic example of functional programming techniques, what with its' pure components. All in all, an enjoyable technology to work with that brings some sanity to front-end user interfaces.

    What are some alternatives to Nunjucks and React?
    Handlebars.js
    Handlebars.js is an extension to the Mustache templating language created by Chris Wanstrath. Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be.
    Twig
    It is a modern template engine for PHP. It is flexible, fast, and secure. Its syntax originates from Jinja and Django templates.
    Pug
    This project was formerly known as "Jade." Pug is a high performance template engine heavily influenced by Haml and implemented with JavaScript for Node.js and browsers.
    Mustache
    Mustache is a logic-less template syntax. It can be used for HTML, config files, source code - anything. It works by expanding tags in a template using values provided in a hash or object. We call it "logic-less" because there are no if statements, else clauses, or for loops. Instead there are only tags. Some tags are replaced with a value, some nothing, and others a series of values.
    EJS
    It is a simple templating language that lets you generate HTML markup with plain JavaScript. No religiousness about how to organize things. No reinvention of iteration and control-flow. It's just plain JavaScript.
