With tools such as Require.js, Bootstrap, Less CSS in general, as well as Knockout.js, jQuery plugins, and browser session caching especially in the checkout experience, supported on the backend side by the Rest API, Varnish, Redis and Elasticsearch it is a huge step forwards a more dynamic and modular architecture but it has some natural limitations.
The Luma frontend theme
The Luma frontend was the first huge step towards a headless architecture and separating the backend and the frontend in Magento. For the next step, however, a bald and radical change had to be embraced, which meant a complete re-invention of the Magento API as well as the frontend.
PWA Studio and The Venia frontend theme
Magento started completely new backend and frontend projects and started to develop a React-based PWA with a GraphQL API backend. PWAs combine the words and benefits of single-page applications, websites and mobile apps: with their offline mode and “add to home screen” feature they act like mobile apps without the need to publish them, they are cross-platform, indexable by search engines, and faster than normal websites thanks to the service workers technology.
Choosing React and GraphQL as the basis for the Magento PWA was probably the best choice, as they are actively maintained, future-proof, widely used and widely supported technologies with a very steep learning curve in general.
Magento’s PWA Studio as of the end of 2020 is still a work in progress, but quite stable and although is missing some important features such as Internationalization and Localization, Multi-Store, some My account features, wider support of payment methods, these functionalities can be added by developer agencies on their own with some effort and can be used in production.
Why is GraphQL so amazing?
GraphQL is flexible both on the client and server side and is fun to work with.
On the server side
- GraphQL APIs are organized in terms of interfaces, types and fields, not endpoints. In Magento 2 Backend, it is easy to create, extend them, or modify the behavior.
- The Magento 2 team is implementing a full coverage of customer data types
- Extension developers already started to implement the GraphQL API for their modules
On the client side
- Developers can use cool tools and documentation
- GraphQL Gives clients the power to control data and ask for what they want and nothing more or less
- It is possible to get structured data in one go traversing the hierarchy of types
- Modifying and querying data can be done in one go
- It is allowed to get many resources in a single request using a single endpoint
- Data can be cached on the type level
- PWA studio implements the powerful and easy to use Apollo Client library to fetch, modify cache application data
The main potential issue with GraphQL is the performance of more complex queries, which can be overcome by wise use and performance optimization.
Why is React so amazing?
The main benefits of ReactJS
- Simple – The React library does one thing: build a user interface. It does this without making assumptions about the underlying technology stack.
- Declarative – Creating a complex user interface is difficult when working directly with the DOM API. React allows to describe how your interface should look for a specific application state.
- Modular – React encourages developers to create modular and reusable components. Taking a modular approach to development makes the code easier to debug and maintain.
Is it recommended to start developing a new PWA Studio website in Q1 of 2021?
With some limitations, it is. Magento PWA Studio is very close to having complete coverage of all the basic features being available for the wider audience but the gaps can be already filled in. Some points to be considered:
- It is best if the webshop uses only a limited number of 3rd party extensions – the frontend of these extensions has to be rebuilt on PWA from scratch as well as any missing GraphQL functionality on the backend side, which increases development time.
- SEO needs extra care, pre-rendering or server-side rendering is recommended
- it is recommended not to deviate too much from the common e-commerce look-and-feel so that existing components can be reused as much as possible
- It is highly recommended to use CDN for static content
