Component library (Storybook)
We create a UI component library in code (e.g. in Storybook): reusable, documented, tested interface components from which developers build the product faster and more consistently. It is the code embodiment of a design system (961). Honestly upfront: a component library speeds up and unifies development, but it is an investment that pays off at SCALE (a large/growing product, several developers); it works ONLY with adoption and maintenance (living code, requires updating); and by itself it does not guarantee product quality — the components still need to be designed correctly.
Component library (Storybook) — overview
A component library is the code implementation of reusable UI elements: buttons, fields, modals, cards etc., formed as isolated, documented, tested components (often in Storybook — a tool for component development and showcase). Developers build interfaces from ready blocks rather than writing each from scratch. It is the technical continuation of a design system (961) in code. Honestly about scale, this is key: a component library is a serious investment (time to create, document, maintain). It genuinely pays off when the product is large/growing, several developers work on the code, and speed and consistency over time matter. For a small project it is often excessive. We will honestly assess whether you need a full library or a simpler component set suffices. Honestly about adoption and maintenance: the library is living code, not a one-off artifact. Value appears only if the team uses it and the library is maintained (new components, dependency updates, sync with design). An abandoned library becomes outdated and diverges from the product. Honestly about 'no quality guarantee': the library speeds up and unifies but does not make the interface good by itself — components must be designed correctly (UX, accessibility, states). Bad components = fast and consistently bad. Honestly about the link: a component library is the code part of a design system (961); ideally synced with design tokens (964) and design. Honestly about the effect: at scale it sharply speeds up development and reduces duplication, but it is an investment with conditions. Honestly about access: access to the code/project and developer involvement are needed. An important boundary: this is a code library; design system (as a whole) — 961; tokens — 964; pattern library — 963. Picture this: instead of 'each component from scratch and differently' — a unified set of reusable blocks in code. The base price starts from 70,000 ₽ (depends on the number of components).
Problems we solve
- Components are written from scratch each time — slow and differently.
- The same element is implemented differently in different places.
- No documentation and component showcase for the team.
- Developing a growing product gets more expensive due to duplication.
What's included in the Component library (Storybook) service
- A library of reusable UI components in code
- Isolation, documentation, showcase (Storybook etc.)
- Component states and basic tests
- An honest assessment: a full library or a simpler set needed
- Honest boundaries (pays off at scale; adoption+maintenance; no quality guarantee)
- Sync with tokens (964) and the design system (961)
- A maintenance plan (living code)
- Handover and review with you
What you get
- A unified set of reusable components in code
- Faster and more consistent development (at scale)
- Documentation and a showcase for the team
- Honest boundaries (an investment; scale, adoption, maintenance needed)
How the work goes: steps
- We assess the scale and needed volume; take design/tokens
- We create components with documentation and tests
- We build in maintenance, honestly set boundaries with you

FAQ
Does every project need a component library?
No, honestly: it is an investment that pays off at scale — a large/growing product, several developers, consistency over time matters. For a small project a full library is often excessive. We will honestly assess whether you need a full library or a simpler component set suffices, rather than offer the maximum for the invoice.
Made a library — and it all speeds up by itself?
No, honestly: a library is living code, not a one-off artifact. Value appears only if the team actually uses it and the library is maintained (new components, updates). An abandoned library becomes outdated and diverges from the product. Without adoption and maintenance it is wasted resources — we honestly build in the process rather than just hand over code.
Does the library guarantee a quality interface?
No, honestly: it speeds up and unifies but does not make the interface good by itself. Components must be designed correctly (UX, accessibility, states) — bad components give a fast and consistently bad result. The library is an efficiency tool, while the quality of decisions inside components is separate work it does not replace.
