Design and Architecture of a B‑End Low‑Code Platform
The article argues that B‑end applications need clear standards rather than technical hurdles, proposes a low‑code platform with front‑back separation into view, template, and engine layers using JSON Schema and a rule engine, and evaluates its benefits, trade‑offs, and implementation considerations.
The article analyses the specific needs of B‑end applications and argues that the core challenge lies in establishing clear standards and rules rather than technical barriers.
It proposes a low‑code approach (pro‑code / low‑code / no‑code) and explains why low‑code is preferred for B‑end scenarios: cost reduction, faster delivery, simplified maintenance, and higher configurability.
The platform architecture follows a front‑back separation and is divided into three layers:
View layer – a component pool, canvas, and property panel that allow users to compose pages visually. Components are defined by JSON Schema and can be combined to generate the final UI.
Template layer – manages JSON Schema, template data, and a rule‑engine adapter that maps business rules to executable expressions.
Engine layer – executes the rule engine, separating business decisions from application code.
The design also covers storage considerations, overall workflow, and logical orchestration, illustrated with diagrams of business flow, complete process, architecture, and layer interactions.
Finally, the article discusses the pros and cons of low‑code platforms, emphasizing that while they bring efficiency, issues such as limited customizability, platform lock‑in, and security risks must be carefully evaluated.
