In this article, we will show you, how you can return an image from the response of an API in Node JS.
Video tutorial:
First, I will create an image tag and set the “src” attribute as the path of the API. I also send “adnan” as an argument so the server will know which image to fetch.
<img src="/showImage/adnan" />Then I am going to create a GET API in Node JS.
const fs = require("fs")
app.get("/showImage/:name", async function (request, result) {
const name = request.params.name
const image = await db.collection("images")
.findOne({
name: name
})
if (image == null) {
let defaultImage = await fs.readFileSync("public/default.jpg")
defaultImage = Buffer.from(defaultImage, "base64")
result.writeHead(200, {
"Content-Type": "image/jpg",
"Content-Length": defaultImage.length
})
result.end(defaultImage)
return
}
const imageContent = await fs.readFileSync(image.path)
result.writeHead(200, {
"Content-Type": "image/jpg",
"Content-Length": imageContent.length
})
result.end(imageContent)
return
})If you run the code now, you will be able to see the image.
