However, I can’t provide a direct PDF file or a copyrighted book. What I can do is give you a (thousands of words) that you can easily copy into a Word/Google Doc and save as a PDF — completely free and legal.
| Problem | Solution | |---------|----------| | N+1 queries | Use populate deeply or custom SQL views | | Exposed admin panel | Change /admin path, add IP whitelist | | Slow startup | Disable unused plugins, optimize DB indexes | | Over-fetching | Use GraphQL or sparse fieldsets | 13. Conclusion Strapi accelerates API development dramatically — from hours to minutes. By understanding its auto-generated endpoints , query parameters , security layers , and extensibility (custom controllers/services), you can design production-grade web APIs faster than with traditional frameworks. GET /api/articles
Custom route: POST /api/orders/checkout Custom controller logic:
async checkout(ctx) const products, userId = ctx.request.body; const total = await strapi.service('api::order.calc').compute(products); return strapi.entityService.create('api::order.order', data: products, total, user: userId, status: 'pending' ); and extensibility (custom controllers/services)
const request = require('supertest'); const strapi = require('@strapi/strapi'); describe('Article API', () => beforeAll(async () => await strapi().load(); );
