WebzstoreA feature is easier to plan when its purpose is clear. Someone may need to compare choices, submit information, update a record or see the status of a request. We map the inputs, response and next step before deciding how to build the interaction.
JavaScript Development
JavaScript Development
Make your website's interactive features work for the people using them. Our JavaScript development work covers browser interactions and application behaviour, from a difficult form to a more involved customer or staff workflow.
01Purpose
Start with what the user needs to do
If something is already broken, share the steps that trigger it, the device or browser involved and what should happen instead. A reproducible example is more useful than a guess about the cause.
02Edge Cases
Handle the less convenient cases
A working demonstration is only the beginning. People submit incomplete forms, lose connections, use keyboards and return to pages after a delay. We include the relevant loading, validation, error and recovery states in the work.
Interaction
Form
Useful checks
Clear labels, validation and submission outcome
Interaction
Search or filtering
Useful checks
Useful empty results and retained choices
Interaction
Data update
Useful checks
Confirmation, permissions and failure handling
Interaction
Navigation
Useful checks
Keyboard access and understandable behaviour
Interaction
Connected service
Useful checks
Loading, timeout and retry behaviour
The agreed test cases depend on the feature. We avoid adding motion or extra steps that make a simple action harder.
03Fit
Fit the existing website
We assess the framework, code and dependencies already in use.
- A targeted change may be more suitable than replacing the application's structure.
- Where the work affects performance or accessibility, we test the relevant journey rather than relying only on a visual review.
04Handover
Keep the handover useful
Your team needs to know what changed, where the feature is managed and how to report an issue.
- We agree those handover needs with the development scope.
- For a larger application, requirements, access and release responsibilities are covered through Web Application Development.
Questions before getting started
Is JavaScript the same as React?
React is one way to build interfaces using JavaScript. The requirement and existing application determine whether it is relevant to your project.
Can you fix a feature without rebuilding the website?
Often that is worth assessing first. We inspect the affected code and its dependencies before confirming the scope.
Will the feature work on mobile?
We agree the required devices and browsers, then test the interaction on the appropriate layouts and input methods.
Tell us the task that feels difficult or the interaction you want customers to have.
