Using colon as a character instead of path parameter (express 5)

[Tanavya]

I am trying to follow google's API design guide here for custom methods https://cloud.google.com/apis/design/custom_methods. I already looked through the discussion here #3857 but it did not solve my problem.

On express version 5.0.0-beta.3.

This works

router.get('/tasks/:id/([:])action', async (req, res, _next) => {
    const id = req.params["id"];
    return res.status(200).send(id);
  });

So I can do a simple GET on tasks/50/:action

However, the moment I remove the / it breaks.

router.get('/tasks/:id([:])action', async (req, res, _next) => {
    const id = req.params["id"];
    return res.status(200).send(id);
});

GET /tasks/50:action -> not found.

How do I solve this?

Have you considered using a RegularExpression instead of a string to define the route?

This was solved in #5610 (comment). I will close this discussion.

Please @Tanavya in the future try to use a single channel (discussions or issues) to avoid duplication.
