Routes' Matching Syntax

Custom regex in params

const routes = [
  // /:orderId -> matches only numbers
  { path: '/:orderId(\\d+)' },
  // /:productName -> matches anything else
  { path: '/:productName' },
]

Now, going to /25 will match /:orderId while going to anything else will match /:productName. The order of the routes array doesn't even matter!

Repeatable params

const routes = [
  // /:chapters -> matches /one, /one/two, /one/two/three, etc
  { path: '/:chapters+' },
  // /:chapters -> matches /, /one, /one/two, /one/two/three, etc
  { path: '/:chapters*' },
]

// given { path: '/:chapters*', name: 'chapters' },
router.resolve({ name: 'chapters', params: { chapters: [] } }).href
// produces /
router.resolve({ name: 'chapters', params: { chapters: ['a', 'b'] } }).href
// produces /a/b

// given { path: '/:chapters+', name: 'chapters' },
router.resolve({ name: 'chapters', params: { chapters: [] } }).href
// throws an Error because `chapters` is empty

Sensitive and strict route options

By default, all routes are case-insensitive and match routes with or without a trailing slash
