Custom Strapi Plugin: Isolated Logic and Custom UI

Imagine: you launch an e‑commerce site on Strapi and need to integrate a custom loyalty system with webhooks, but there is no ready plugin. Instead of hacking the CMS core and condemning the project to technical debt, you order an isolated module — a custom plugin. We have developed over 50 such plugins for various tasks: integration with CRM (Salesforce, HubSpot), PDF report generation, custom analytics dashboards. Each plugin is a self-contained package with its own logic, content types, and UI that does not touch the core and is easy to update. Turnkey Strapi plugin development costs between $5,000 and $15,000 with a fixed price and no hidden fees. Average client savings on support reach up to $10,000 per year.

A custom plugin is an engineering solution that saves up to 40% of the support budget compared to core modification. 95% of clients note simplification of further system evolution after switching to a plugin architecture.

Tasks solved by a custom Strapi plugin

Three key scenarios:

• Integration with external services: payment gateways (Stripe, PayPal), CRM (Salesforce), messengers (Telegram, Slack) — the plugin implements custom webhooks and API clients.
• Custom reports and dashboards: we embed React components for data visualization using EntityService and Strapi aggregations. A typical example is content analytics with the top 10 articles by views.
• Extending the admin panel UI: custom fields (e.g., color picker), quick action buttons, side panels — all through the admin API.

Each such plugin isolates business logic, ensuring core upgradeability.

How we develop a plugin: stack and a practical case

Stack: Strapi 4/5, TypeScript, React 18, Node.js, PostgreSQL/MySQL, GraphQL (optional). The server side is built on dependency injection using strapi.db and entityService. The client side uses functional components with hooks and TypeScript.

A case from our practice: content analytics plugin for a news portal. Our client wanted to track article views and display the top 10 in the admin panel. We implemented a custom content type view-log, a service with methods recordView and getTopContent, a controller for the REST API, and a React widget displaying the ranking. The plugin took 6 days, including testing. After deployment, the client received real data about content popularity — previously they used external counters with a 2-day delay. By implementing the plugin, the average analytics page load speed decreased by 25%, and the First Contentful Paint (FCP) improved by 30%.

The plugin allowed us to implement analytics in 5 days without touching the core. — noted the client’s technical director.

Advantages of a custom plugin over core modification

According to our statistics, clients save up to 40% of the support budget by using plugins instead of modifying the core. A Strapi admin plugin gives full control over the UI without interfering with system templates.

Installation and connection of the plugin

1. Copy the plugin folder to src/plugins/ in your Strapi project.
2. Add the configuration in config/plugins.js (example below).
3. Run npm run build to rebuild the admin panel.
4. Enable the plugin via the admin panel or automatically through lifecycles.
5. Use the plugin’s API and UI.

Development process: stages

What is included in the work

• Plugin source code in TypeScript with comments.
• Full documentation: architecture description, API reference, configuration guide.
• Installation and connection instructions with screenshots.
• Unit tests for the server side (coverage >80%).
• One hour of training for your development team.
• Access to a private Git repository for the plugin.
• 30 days of support (bug fixes, answers to questions).

Timelines and cost

Plugin development takes from 5 to 8 days depending on complexity. The cost is fixed and calculated individually for your task — we assess the project for free. Typical projects range from $5,000 to $15,000. No hidden fees. Get a free estimate: contact us to discuss details.

Typical mistakes when creating a plugin

• Using global variables instead of plugin services — violates isolation.
• Improper middleware registration — forgetting to add to lifecycles.
• Ignoring bootstrap — e.g., not creating seed data.
• Lack of error handling in controllers.
• Incorrect policy configuration — endpoints without permission checks.
