title: "ADR: Interface naming"

## Background
|
||
|
|
|
||
|
|
In the codebase, we have found a need to have a common way of naming interfaces in order to ensure consistency.
|
||
|
|
|
||
|
|
## Decision
|
||
|
|
|
||
|
|
We have decided to use a naming convention of appending the letter `I` in front of interfaces to signify that we are in fact using an interface. For props, we use `IComponentNameProps`.
|
||
|
|
|
||
|
|
```jsx
|
||
|
|
// Do:
|
||
|
|
interface IMyInterface {}
|
||
|
|
interface IMyComponentNameProps {}
|
||
|
|
|
||
|
|
// Don't:
|
||
|
|
interface MyInterface {}
|
||
|
|
interface MyComponentName {}
|
||
|
|
```
|
||
|
|
|
||
|
|
The reason for this decision is to remove mental clutter and free up capacity to easily navigate the codebase. Knowing that an interface is prefixed with `I` allows you to quickly scan a file without watching for a context where the interface is used in order to understand what it is.
