Snapshot a React Native view and save it to an image.
import RNViewShot from "react-native-view-shot";
RNViewShot.takeSnapshot(viewRef, {
format: "jpeg",
quality: 0.8
})
.then(
uri => console.log("Image saved to", uri),
error => console.error("Oops, snapshot failed", error)
);

RNViewShot.takeSnapshot(view, options)
Returns a Promise of the image URI.
view
is a reference to a React Native component.options
may include:
width
/ height
(number): the width and height of the image to capture.format
(string): either png
or jpg
/jpeg
or webm
(Android). Defaults to png
.quality
(number): the quality. 0.0 - 1.0 (default). (only available on lossy formats like jpeg)result
(string), the method you want to use to save the snapshot, one of:"file"
(default): save to a temporary file (that will only exist for as long as the app is running)."base64"
: encode as base64 and returns the raw string. Use only with small images as this may result of lags (the string is sent over the bridge). N.B. This is not a data uri, use data-uri
instead."data-uri"
: same as base64
but also includes the Data URI scheme header.filename
(string): the name of the generated file if any (Android only). Defaults to ReactNative_snapshot_image_${timestamp}
.Snapshots are not guaranteed to be pixel perfect. It also depends on the platform. Here is some difference we have noticed and how to workaround.
collapsable
is set to false
if you want to snapshot a View. Otherwise that view won’t reflect any UI View. (found by @gaguirre)Uri
. the file
result returns an Uri
so it’s consistent with iOS and you can give it to Image.getSize
for instance.npm install --save react-native-view-shot
