Troubles Reading / Writing search params using solid-router useSearchParams()

Hello, I have some trouble reading/writing an array of search params using solid-router/useSearchParams() primitive

// for an URL like ?plop=a&plop=b
function MyComponent () {
  const [searchParams, setSearchParams] = useSearchParams()
  console.log(searchParams.plop) // 'b' when I wanted ['a', 'b']
  return (
    <button
      onClick={() => {
        setSearchParams({ pouet: ['a', 'b'] }) // update params like ?plop=a&plop=b&pouet=a%2Cb when I wanted ?plop=a&plop=b&pouet=a&pouet=b
      }}>
      Update search params
    </button>
}

// for an URL like ?plop=a&plop=b
function MyComponent () {
  const [searchParams, setSearchParams] = useSearchParams()
  console.log(searchParams.plop) // 'b' when I wanted ['a', 'b']
  return (
    <button
      onClick={() => {
        setSearchParams({ pouet: ['a', 'b'] }) // update params like ?plop=a&plop=b&pouet=a%2Cb when I wanted ?plop=a&plop=b&pouet=a&pouet=b
      }}>
      Update search params
    </button>
}

Do you have any tips to make it work ?

Setting the same parameter twice is not supported at the moment

Ok, so the best way to do it currently would be to serialize / deserialize manually like so ?

const serializeParams = (params = {}, joinChar = '|') => {
  return Object.fromEntries(Object.entries(params).map(([key, value]) => [key, Array.isArray(value) ? value.join(joinChar) : value]))
}
const deserializeParams = (params = {}, joinChar = '|') => {
  return Object.fromEntries(
      Object.entries(params)
        .map(([key, value]) => [key, value.includes(joinChar) ? value.split(joinChar) : value])
      )
  )
}

// for an URL like ?plop=a|b or ?plop=a%7Cb
function MyComponent () {
  const [searchParams, setSearchParams] = useSearchParams()
  console.log(deserializeParams(searchParams).plop) // ['a', 'b']
  return (
    <button
      onClick={() => {
        setSearchParams(serializeParams({ pouet: ['a', 'b'] })) // will update params like ?plop=a%7Cb&pouet=a%7Cb
      }}>
      Update search params
    </button>
}

const serializeParams = (params = {}, joinChar = '|') => {
  return Object.fromEntries(Object.entries(params).map(([key, value]) => [key, Array.isArray(value) ? value.join(joinChar) : value]))
}
const deserializeParams = (params = {}, joinChar = '|') => {
  return Object.fromEntries(
      Object.entries(params)
        .map(([key, value]) => [key, value.includes(joinChar) ? value.split(joinChar) : value])
      )
  )
}

// for an URL like ?plop=a|b or ?plop=a%7Cb
function MyComponent () {
  const [searchParams, setSearchParams] = useSearchParams()
  console.log(deserializeParams(searchParams).plop) // ['a', 'b']
  return (
    <button
      onClick={() => {
        setSearchParams(serializeParams({ pouet: ['a', 'b'] })) // will update params like ?plop=a%7Cb&pouet=a%7Cb
      }}>
      Update search params
    </button>
}

yes.

i wonder why searchParams isn't exposed you could still use a new instance for de/se though
