@anandaroop/react-blurred-pii v0.1.2

react-blurred-pii

This libary provides React components that can be used for protecting personally identifying information (PII) in screenshots and screencaps. It does so by blurring them with pure CSS techniques.

Note that the resulting UI is is thus safe to document visually, but not safe to share with untrusted users, since all PII remains in the markup itself.

If that meets your needs, using it is simple.

Installation

Install, e.g. with Yarn:

yarn add @anandaroop/react-blurred-pii

Basic usage

Consider this simple app:

const Demo = () => {
  return (
    <MyApp>
      <MyComponent>Name: {fullName}</MyComponent>
    </MyApp>
  )
}

The first step is to wrap your app (or some component tree) in a BlurredPIIProvider and toggle the shouldBlur flag to true or false, as needed.

+import { BlurredPIIProvider } from "@anandaroop/react-blurred-pii"

 export const Demo = () => {
   return (
+    <BlurredPIIProvider shouldBlur={true}>
       <MyApp>
         <MyComponent>Name: {fullName}</MyComponent>
       </MyApp>
+    </BlurredPIIProvider>
   )
 }

Once wrapped, any descendant PII component will follow suit by blurring or un-blurring accordingly.

-import { BlurredPIIProvider } from "@anandaroop/react-blurred-pii"
+import { BlurredPIIProvider, PII } from "@anandaroop/react-blurred-pii"

 export const Demo = () => {
   return (
     <BlurredPIIProvider shouldBlur={true}>
       <MyApp>
-        <MyComponent>Name: {fullName}</MyComponent>
+        <MyComponent>Name: <PII>{fullName}</PII></MyComponent>
       </MyApp>
     </BlurredPIIProvider>
   )

The final result:

import { BlurredPIIProvider, PII } from "@anandaroop/react-blurred-pii"

export const Demo = () => {
  return (
    <BlurredPIIProvider shouldBlur={true}>
      <MyApp>
        <MyComponent>Name: <PII>{fullName}</PII></MyComponent>
      </MyApp>
    </BlurredPIIProvider>
  )
}

PII Options

PII has sensible defaults for blurring short snippets of typical body text, but is customizable as well.

as: string

PII will render a span by default, but you can choose any other HTML element:

<MyComponent>
  Name: <PII as="pre">{fullName}</PII>
</MyComponent>

color: string

PII assumes black text, but can generate a blur in any other color as well.

<MyComponent>
  Name: <PII color="red">{fullName}</PII>
</MyComponent>

blurAmount: number

PII generates an 8px blur by default, adequate for typical body text. But it can be customized for larger text sizes.

<MyComponent>
  Name: <PII blurAmount={20}>{fullName}</PII>
</MyComponent>

additionalCSS: object

If you need additional inline styles other than what PII generates, you can provide those as well.

<MyComponent>
  Name: <PII additionalCSS={{
    lineHeight: "2em",
    letterSpacing: "0.5em",
  }}>{fullName}</PII>
</MyComponent>
