# Angular Development

Modern Angular applications for structured, form-heavy products, with typed services, reusable controls and deliberate release management.

**Customer application**

1 Details **2 Documents** 3 Review

Reference **APP-104**

Attachment **Choose a file**

Client rules and server validation

## Tools & technologies

-   Angular
-   TypeScript
-   RxJS where needed
-   HTTP APIs

## Submit a multi-step application

Capability Example

A customer completes a form containing conditional fields and attachments.

### Validate

### Submit

### Recover

Illustrative data. Nothing is sent to an external system.

Example workspace 1 / 3

### Typed form

-   Step: attachments
-   Conditional fields validated
-   Completed steps retained

Apply shared field rules and preserve completed steps.

### API submission

-   Payload version: 1
-   Attachment reference included
-   Application request sent

Send a versioned payload through a typed service.

### Field recovery

-   Server rejects document type
-   Error shown on attachment step
-   Earlier answers remain available

Map server errors back to the relevant field and step.

A submission reference or an editable form positioned at the unresolved issue.

Follow the record through the next step

## Structured applications for connected workflows.

### Business workspaces

Complex record editing and role-specific navigation for operational teams.

### Customer portals

Multi-step forms, document submission and status tracking.

### Angular upgrades

Move supported application versions forward with regression coverage.

## Modules, contracts and a tested release.

-   **Angular feature modules**
-   **Validated form controls**

-   **Service and journey tests**
-   **Upgrade and build documentation**

## Make the application boundaries explicit.

### Version compatibility

Align framework, UI library and build tooling versions before implementation.

### Form complexity

Conditional rules and accessible error handling need examples from the real process.

## Questions before we start.

### Is AngularJS included here?

AngularJS is a different framework and has its own service page. Migration between them is planned as an application change, not a routine version upgrade.

### Can we keep our existing API?

Yes. Typed contracts, authentication and error conventions form the boundary between the Angular client and backend.
