Lightning Web Components (LWC) Development Services
Pashtek builds custom Lightning Web Components, Aura components, and Lightning UI extensions for Salesforce enterprises. Modern JavaScript. 95%+ test coverage. US-based certified developers.
Lightning Web Components — Salesforce’s modern UI framework
Lightning Web Components (LWC) is Salesforce’s modern UI framework built on web standards (ES6+, Custom Elements, Shadow DOM, Web Components). LWC replaced the older Aura framework as the recommended approach for building custom Salesforce UI — faster rendering, smaller bundles, easier testing, and better developer experience.
Pashtek has shipped 200+ Lightning Web Components for Salesforce enterprises across industries. Every component ships with unit tests, accessibility compliance, and mobile-responsive design.
LWC vs Aura Components — When to Use Each
| Aspect | Lightning Web Components (LWC) | Aura Components (Legacy) |
|---|---|---|
| Framework | Modern web standards (ES6+) | Legacy proprietary framework |
| Performance | Faster rendering, smaller bundles | Slower, larger bundle sizes |
| Testing | Jest unit testing built-in | Limited testing options |
| Salesforce recommendation | Preferred for all new development | Only for legacy maintenance |
| Developer experience | Modern JS tooling, VSCode support | Older tooling, harder debugging |

Should I migrate from Aura to LWC?
Yes, for most enterprises. Salesforce recommends LWC for all new development, and LWC offers better performance, easier testing, and modern JS tooling. If you have legacy Aura components in maintenance mode, migration timing depends on your enhancement roadmap.
Can LWC be used in Salesforce Mobile?
Yes. Lightning Web Components work in the Salesforce Mobile App. Pashtek builds mobile-first LWC with responsive layouts, touch-friendly interactions, and offline support where needed.
What testing framework does LWC use?
LWC uses Jest for unit testing — the same framework used by React and other modern JavaScript libraries. Pashtek writes Jest tests for every LWC component, achieving 95%+ code coverage on component logic.
Can LWC integrate with external APIs?
Yes. LWC can call external APIs through Apex proxies (recommended for security), Named Credentials, or directly via fetch() for public APIs. Pashtek regularly integrates LWC with REST, SOAP, GraphQL, and OAuth-secured APIs.
Does LWC support Experience Cloud (Communities)?
Yes. LWC is fully supported in Salesforce Experience Cloud for building custom customer portals, partner portals, and self-service communities. Pashtek has built multiple LWC-powered Experience Cloud sites.
What’s Lightning Message Service (LMS)?
Lightning Message Service is Salesforce’s built-in pub/sub messaging system for cross-component communication. LMS lets LWC, Aura, and Visualforce components exchange messages without direct references. Useful for loosely-coupled architectures.
Does Pashtek follow accessibility standards?
Yes. Every LWC we ship is WCAG 2.1 AA compliant — keyboard navigation, screen reader support, ARIA labels, and color contrast meeting accessibility standards. Accessibility isn’t optional; it’s built into our definition of done.
