Why is trailing slash added?

Question

Vue.js

:to="{name: 'slug', params: {slug: article.slug}}"

adds a slash

http://example.com/qui-in-similique-necessitatibus-est/

while doing everything right

:to="article.slug"

http://example.com/qui-in-similique-necessitatibus-est

Answer 1

In the first case, the router generates the URL itself, and adds a slash at the end. More details https://github.com/vuejs/vue-router/issues/1273
In the second case, it doesn't form anything, it uses what you passed in toas is.
