Minor Feature: m.route.Link bypass:boolean

[ancms2600]

Mithril version: 2.x

Browser and OS: Firefox Quantum Developer Edition, Kali Linux

Project: Internal-only corporate tooling

Is this something you're interested in implementing yourself? Already did but too lazy to make patch upstream. Really only going to the trouble of sharing in case it inspires someone else, which would also imply there is a use for it beyond my case.

Description

Add a bypass:boolean attribute to the m.route.Link component.

Why

Because, before I upgraded Mithril 1.x => 2.x, in many cases I was conditionally binding:

m('a', { oncreate: something ? undefined : m.route.link }, ...);

now becomes:

m(app.components.Link||m.route.Link, { bypass: something });

Possible Implementation

app.components.Link = {
    view(v) {
        if (v.attrs.bypass) {
            return m(`${v.attrs.tagName||'a'}${v.attrs.selector||''}`, _.omit(v.attrs, ['tagName','selector','bypass']), ...v.children);
        }
        else {
            v.attrs.selector = (v.attrs.tagName||'a') + (v.attrs.selector||'');
            delete v.attrs.bypass;
            delete v.attrs.tagName;
            return m(m.route.Link, v.attrs, ...v.children);
        }
    }
};

Open Questions

Practically, I would do this when href.startsWith('http'), but in other cases as well,
such as on the page header logo, which I want to cause a full-page refresh if clicked.
