I have an example JSON file like the following:
menu.json
{
"0":{
"img":"./101 cup noodles.png"
},
"1":{
"img":"./102 cup noodles with beef.png"
},
"2":{
"img":"./103 cup noodles with egg.png"
},
"3":{
"img":"./104 cup noodles with shrimp.png"
}
}
Is there any way to dynamically create import statements for each of the image links inside the JSON file for webpack to build?
I would like to avoid having to write an individual import for each image at the top of my javascript file especially if there are hundreds of items. E.g:
menu.js
import img0 from './101 cup noodles.png'
import img1 from './102 cup noodles with beef.png'
import img2 from './103 cup noodles with egg.png'
import img3 from './104 cup noodles with shrimp.png'
I have tried dynamically making the import statements with named fields and a for loop but learned that import statements need to be top level so unfortunately the following did not work:
menu.js
import data from './menu.json'
for (let i = 0; i < Object.keys(data).length; i++) {
import ['img' + Object.keys(data)[i]] from data[i]['img'];
}
At the moment I am using the loop above to console log all of my import statements and just copy+pasting them into the top of my code but that seems extremely inelegant and I am wondering if there is a better way.
You can get the properties of the object with Object.keys, then map through the array and construct the string.
const obj = {
"0":{
"img":"./101 cup noodles.png"
},
"1":{
"img":"./102 cup noodles with beef.png"
},
"2":{
"img":"./103 cup noodles with egg.png"
},
"3":{
"img":"./104 cup noodles with shrimp.png"
}
}
const res = Object.keys(obj).map(e => `import ${Object.keys(obj[e])[0] + e} from '${obj[e].img}'`).join('\n')
console.log(res)
