Lightning Web Components Development
Custom Lightning Web Components that fit how your users work, built on standard platform services, tested with Jest and styled to match Lightning Experience.
Standard Lightning pages cover a lot, but some tasks need a better screen. A service agent might need customer, order and case history side by side. A sales rep might need a guided quote builder. A partner portal might need a self-service form that validates input as it is typed. Lightning Web Components (LWC) let you build these interfaces on the Salesforce platform using modern JavaScript and web standards.
We build LWCs for internal Lightning apps, record pages, utility bars, screen flows and Experience Cloud sites. The goal is always the same: an interface that saves users time, respects Salesforce security and is easy for your team to maintain.
When a custom component is worth it
- Users switch between several records or tabs to complete one task.
- A process needs dynamic, conditional input that standard page layouts and Dynamic Forms cannot handle.
- A screen flow needs a custom input or display component.
- An Experience Cloud site needs interactive features beyond the standard components.
- Older Aura or Visualforce components need replacing because they are slow or hard to maintain.
If standard components, Dynamic Forms or a screen flow can do the job, we will say so. Custom UI adds code your team has to own.
What we deliver
Record page components
Components that combine related data, show calculated values or guide users through next steps on a record.
→Screen flow components
Custom inputs and displays that plug into Flow, so admins keep control of the process logic.
→Experience Cloud components
Portal and site components designed for external users, with guest and authenticated access considered from the start.
→Aura and Visualforce modernisation
Rebuilding older UI as LWC, with an inventory and a sensible migration order.
Apex back ends
Cacheable, secure Apex controllers where Lightning Data Service is not enough.
→How we build components
Lightning Data Service first. Where a component reads or edits records, we use Lightning Data Service wire adapters and base components such as lightning-record-form before writing Apex. LDS respects field-level security and sharing, caches data across components and keeps the page in sync when records change.
Apex only where it adds value. Complex queries, aggregations or calls to external systems go through Apex controllers that enforce user permissions, for example with WITH USER_MODE in SOQL, and that are marked cacheable where the data allows.
Small, composable components. Parent components manage data and state; child components handle display and raise events. This keeps each piece testable and reusable.
Consistent styling and accessibility. We use base Lightning components and the Salesforce Lightning Design System so components look native, and we check keyboard navigation, labels and focus handling.
A small example
The component below reads two fields from the current Account using LDS, with no Apex. It assumes a custom field named Customer_Tier__c exists on Account and is shown on an Account record page, which supplies recordId.
import { LightningElement, api, wire } from 'lwc';
import { getRecord, getFieldValue } from 'lightning/uiRecordApi';
import NAME_FIELD from '@salesforce/schema/Account.Name';
import TIER_FIELD from '@salesforce/schema/Account.Customer_Tier__c';
export default class AccountTierBadge extends LightningElement {
@api recordId;
@wire(getRecord, { recordId: '$recordId', fields: [NAME_FIELD, TIER_FIELD] })
account;
get tier() {
return this.account.data
? getFieldValue(this.account.data, TIER_FIELD)
: null;
}
}From idea to deployed component
- 01
Understand the task
We watch or walk through how users do the task today and agree what the component must make faster or safer.
- 02
Sketch and agree
A simple wireframe and a list of data sources, actions and permissions, reviewed with users before build.
- 03
Build and unit test
Components built in a sandbox with Jest tests for rendering, events and data states, including loading, empty and error states.
- 04
Test with real personas
Functional and accessibility testing with users who have the same permission sets as production users.
- 05
Deploy and document
Deployment through your pipeline, Lightning App Builder configuration notes and developer documentation for future changes.
What we need from you
Access to a sandbox with representative data, a product owner who can make design decisions, and time with a few real users for feedback on the wireframe and the finished component. For Experience Cloud work we also need clarity on which users are guests and which are authenticated, because that shapes what data a component may show.
Risks we manage
Custom components can slow pages if they load too much data, and they can expose data if Apex controllers ignore user permissions. We keep queries selective, load data only when needed and review every Apex method a component calls for security. Platform security features such as Lightning Web Security also restrict what third-party JavaScript libraries can do, so we check library compatibility before committing to one.
Questions we hear
Should we rebuild all our Aura components as LWC?
Can LWCs be used inside screen flows?
Do you write tests for components?
Can we use third-party JavaScript libraries?
Will our admins be able to configure the components?
Need a better screen for your users?
Describe the task your users find slow or awkward today. We will tell you whether standard features can solve it or whether a custom component is the better route.
