How to delete multiple data with with the req.params.ids (multiple ids)

Question

app.delete('/poems/delete:ids',(req,res,next)=>{
    //here req.params.ids carries the multiple id i.e 1,2,3

});

In the above code, how can I delete all data with the requested ids that is the data's containing ids 1,2,3

 this.http.delete('http://localhost:3000/poems/delete' + ['1','3','4']);

2 things - why use the DELETE verb with a CRUD URL? Also, if ids are arbitrary then you'd be best using POST and passing the IDs up in the body given URLs have a maximum length. — James

can u please, why req.params.ids stores the values in the format like: 1,2,3 instead of [1,2,3] . — Bhupendra Thapa

The best practice in this case is to submit a POST request, whose body is an array of IDs. In that case, your controller would get req.body.ids and delete them accordingly.

The DELETE HTTP Method is used for single deletions.

I faced the same issue.

For deleting multiple ids, it's better to use DELETE since it's the more semantically correct method for resource deletion. However, DELETE has some limitations:

DELETE does not support a request body in some browsers and HTTP clients (though in practice, most servers allow it).
POST is more flexible and universally supported, but it is semantically meant for creating or processing data, not deleting it.

Possible Approaches which I find:

Use DELETE with query parameters:

DELETE /users?ids=1,2,3,4

The server retrieves ids from the query parameters and deletes them.

Use DELETE with a request body (if supported by the server):

DELETE /items
Content-Type: application/json

{
    "ids": [1, 2, 3, 4]
}

Use POST (if DELETE with a request body is not supported):

This approach is more compatible but less RESTful.
