How to have same backend for Flutter mobile app as of nodeJS website?

Question

I already have a website with nodeJS and EJS templating engine. I know I should configure my server to return data in JSON format in order to have a backend for the flutter app.

I don't have much computer background and I'm a bit confused.

Here is what I'm doing in my website codes.

 router.get("/", (req, res) => {
 res.render("home", someData)
})

Solution

Just created different route for website and flutter application.

Route for website :

router.get("/api/web", (req, res) => {
    res.render("home", someData)
})

Route for mob-application :

router.get("/api/app", (req, res) => {
    //send response
})

you can create a new route like /api/ where you will serve json, or do you intend to sharee the same route between you webapp and flutter ?

I was thinking of the same route.

But if that's the only way, then I'll create a new route.

else you can return json, and use Flutter for your webapp and mobile, like that you will share the same code https://www.filledstacks.com/post/create-and-deploy-a-flutte‌​r-web-app/

you can use Dio or Http packages in Flutter in order to send request to your backend API.
