Wefram web platform

Wefram platform

Wefram is the open source platform used to create complex web projects consisting of both backend and frontend parts, allowing using both SSR (server-side rendering) using template renders, and CSR (client-side rendering) using React based SPA (single page application) approach.

The main point is to handle as much as possible repeating or taking much of time elements of the development process by the platform (let's not name is "framework", okay?), giving programmers time to make end-point code of corresponding project applications only.

The another goal of using Wefram is the ability of dividing the entire project into applications, often independent on each other. This provides us the posibility to write sometimes small, somethimes just funtion-resolving modules (applications) and store them in the repository, and re-use when needed. You may see many analogies with other module-based frameworks such as Django or Flask. But Wefram takes in work a lightly much, then those frameworks, providing already pre-developed, ready to use frontend SPA platform (React-based), and programmers of the project only focuses on the target functional code of the project modules, not wasting time on the frontend basics development, SSR & CSR integration into a single project, etc.

Approach

The platform consists of itself (installed from pypi with pip) and developed and enabled project's applications. So, the final project will have a set of modules, named "applications", placed in the project's directory, and a set of backend and frontend third-party packages (both for backend & frontend).

Provides

The platform itself provides some most used functionality and facilities, ready to use from the box, such as:

• Applications' management: the project's modules, named application management, allowing to install and deinstall project's apps, enable and temporary disable, and providing the dividing of the entire project on (most often) independent parts, with dynamic inclusion and exclusion in and from the final build.
• Dependencies resolving: application's and platform's dependencies summarizing and resolving, both for backend (Python with pip) and frontend (React@TypeScript with yarn).
• PostgreSQL database dialect and special types support.
• State-based migration with no needing of any kind of migration history or scripts generating.
• In-memory database (Redis) connectivity, caching facility, etc.
• ORM (Object relating modeling) with files storage transparent integration.
• ORM history facility with automated logging of changes in models' instances.
• Files storage for uploadable content with ready-to-use support from the platform side, including all routings and handlings.
• Localization extended facility with domains support both on backend and frontend.
• Routing facility for both HTTP(S) and WebSockets.
• API functionality out of box, with ready-to-use ORM models DTO allowing to make any ORM model API-ready in really two lines of code.
• Template rendering for SSR (server-side rendering) using Jinja2 template engine.
• Frontend ready-to-use React implementation.
• Material-UI implementation with extended set of common purpose components.
• User interface out of box, with no need to code anything from the scratch, with the theming facility.
• Settings ready-to-use facility (the application is not required to have the own implementation).
• Users & roles facility out of box - Authentication, Authorization and Accounting, roles' permissions management, etc.
• Permissions handling out of box for most entities, such as API, Views, Screens, Settings, etc.
• CLI (command-line interface) basics to implement command line management facilities.
• Notifications (displayed to users), messages transports between backend and frontend.
• Sidebar and Sidemap automated facility.
• Screens (client-side rendered) facility, even managed screens with backend runtime qualifications.
• Typo screens automatisations to exclude needing of writting any line of the 'React @ TypeScript' code for very common cases.

As been said - the platform aims to make programmers work on the corresponding project's code.

Written on

Like any client-server project, the Wefram-based project will consist of two main parts:

• Backend, which is written in Python 3.
• Frontend, which is written mainly in TypeScript & React or templated HTML.

The frontend part is lightly more interesting than just a TypeScript or just a React. While we speak about two variants of render - SSR & CSR, we about to handle two different approachs.

If we speak about regular, search engines (Google, Yandex...) indexing site - we usually speak about SSR with pre-rendered HTML code returning to the browser. Wefram uses Jinja2 template engine to render the HTML on the server side. To provide assets like CSS, JS scripts and so on, the Wefram uses assets approach, which makes possible to build assets from all enabled applications into understandable and easy to use structure, which can be directly handled by the web server like nginx or apache.

If we speak about site's administrative panel, about corporate portal, about some another kind of business logics, used primary on workplaces - we speak about SPA (single page application), we speak about CSR (client-side rendering), about traffic economy, reusing same pre-built program code by clients' browsers without needing of reloading everything. Here we speak about React which is based (in our configuration) on TypeScript.

The Wefram combines both described above approachs into one project. This means that a single project may have both SSR and CSR applications, modules, etc. This allows not to divide a project into independent parts, combining all in one place.

This not requires, for example, the project to have SSR pages. Wefram gives this posibility, but only when the project needs it. For example, if we have a regular site, for example with a set of services for the end user, and we want to make a some kind of reservation system for those services - we will make several SSR pages (to be easyly indexed by search engines) basing on Jinja2, HTML, CSS and pure JS; and make a workspace for employee, administering those reservations and services, with CSR using React & TypeScript.

Applications

While many projects divides the entire project horizontally - to the "all backend" and "all frontend", the Wefram uses another approach - it dividing the entire project vertically, to "modules", names "applications".

The every application consists of backend part (even almost empty) and optional frontend part. Why the frontend is optional? Because (a) the application may handle some work without any client side control (for example, make regular integration with another service, or give a facility on, for example, sending messages via Telegram), and (b) because Wefram gives several interesting backend-realized approachs, whose may exclude needs of frontend programming for simple tasks (for example, the applicaion's programmer relieved of the need to make settings, properties handling, administering simple database models on the frontend and so on).

So, while the application consists of both backend and frontend, it makes much easier to install to the project and deinstall from the project applications, developing application outside the main project and then easily adding it to the project, etc. The point is that makes much easily to divide the entire project into reusable and often independent parts.

Localization

One of the main our targets was to make the platform localization-ready from the begining, as one of main goals. Because of this, everywhere, where that is possible, we made the localization interfaces and interesting localization approach. We will speak about it in the documentation, in the separate section.

Where we are

The Wefram is in active development and about 80% ready to be published. Much of work on documenting is still in progress (which take a lot of time), some interesting ideas are in progress.

But several really living projects are already in live, already basing on the Wefram platform and successfully working.
