async function handleit(id){
    return new Promise(async (resolve, reject) => {
	var k = new Klog();
	k.log("Running on ID: "+id);
	const search = await knex("posts").where("id", "=", id)
	.then(function(rows){
	    if(rows.length==0)
		    k.warn("No result on ID"+id);
	    }else if(rows.length==1){
		    const row = rows[0];
		    k.log("Found "+row);
		    resolve(k.done())
	    }else{
		    reject(k.err("Too many found!"))
	    }
	})
	.catch(function(err){
	    reject(k.err("Error in db: "+err));
	})
    })
}

router.get(["/endpoint/:id"], async function(req, res){
	if(req.params.id && isNumber(req.params.id)){
		const id = req.params.id;
		await handleit(id)
		.then(function(data){
			res.status(data.httpcode).send(data);
		})
		.catch(function(data){
			res.status(data.httpcode).send(data);
		});
	}else{
		var out = new Klog().bad("ID is not a number!")
		res.status(out.httpcode).send(out);
	}
})
