I've been looking for a way to get paths of images stored locally in my project from a JSON file . I already saw answers suggesting dropping the JSON file and using an array in a .JS file instead, just like this:
const DATA = [
{
"ID": 0,
"Image": require('../assets/image0.png')
},
{
"ID": 1,
"Image": require('../assets/image1.png')
}
]
Thing is I can solely use a JSON file to get my data from, which results from converting an Excel to JSON file , and nothing else. So let's say I have a data.json file as follows:
{
"data": [
{
"ID": 0,
"Image": "require('../assets/image0.png')"
},
{
"ID": 1,
"Image": "require('../assets/image1.png')"
}
]
}
Currently, it is not possible to use the paths stored in the "Image" attributs as a source in <Image source = {}/>
to display an image. Does somebody know a way to conserve the JSON file and somehow get and use the paths from it?
EDIT:
My structure:
- assets
- favicon.png // Image I want to display
- icon.png // Image I want to display
- screens
- File1.js // Where I want to display images
- images.json // From where to get paths
File1.js
// Other imports
import assets from "./images.json;
require("../assets/favicon.png");
require("../assets/icon.png");
const File1 = () => {
return (
<View>
{assets.data.map((i) => (
<Image
source={{
uri: require(i.Image.replace("require('", "").replace("')", ""))
}}
resizeMode="contain"
style={styles.logo}
/>
))}
{/*<Image source={require('../assets/favicon.png')}></Image> Its working but not above*/}
</View>
)
};
export default File1;
const styles = StyleSheet.create({
logo: {
height: 80
},
});
images.json
{
"data": [
{
"ID": 0,
"Image": "require('../assets/favicon.png')"
},
{
"ID": 1,
"Image": "require('../assets/icon.png')"
}
]
}
But getting:
TransformError src\screens\File1.js: src\screens\File1.js:Invalid call at line 323: require(i.Image.replace("require('", "").replace("')", ""))

You need to store in an array only the path, for example:
const images = {data : [
{
"ID": 0,
"Image": "require('../assets/image0.png')"
},
{
"ID": 1,
"Image": "require('../assets/image1.png')"
}
]}
and in your render component:
return (<>{
images.data.map(i => <Image source={require(i.Image.replace("require('", "").replace("')", ""))}/>)
}</>)
