I'm trying to pass a var to the axios more by what I'm seeing it just accepts string is there any way to pass a var ?
My code:
router.get('/albuns', async (req, res)=>{
const response = await axios.get(req.query.id)
return console.log(response)
})
Error:
Argument of type 'string | ParsedQs | string[] | ParsedQs[] | undefined' is not assignable to parameter of type 'string'.
Type 'undefined' is not assignable to type 'string'.
This is just a Typescript warning because axios.get() expects a string argument but the default req.query can provide various types.
You just need to cast the value
const response = await axios.get(req.query.id as string);
Another option is to type the request in your handler signature
import { Request } from "express";
interface AlbunsQuery {
id: string;
}
type AlbunsRequest = Request<{}, any, any, AlbunsQuery>;
router.get("/albuns", async (req: AlbunsRequest, res) => {
const response = await axios.get(req.query.id);
// etc
});
URL parameters aren't supported, and it seems they have no intention on adding it, given they expect you to use template strings. Here there's a discussion: https://github.com/axios/axios/issues/706
Axios GET method takes two arguments: the first being the URL string, and the second argument, we have it configure object with the property called params.
Axios Code:
axios.get("http://localhost/example"){
params{
name: myName
example: 2
}}
Express Code:
app.get("example", (req, res){
const name : request.query.name
const example: request.query.example
}
