Variable: filterAsyncOrThrow

const filterAsyncOrThrow: never

Defined in: async/filterAsync/index.ts:152

Throwing variant of filterAsync for backward compatibility.

Use this when you want exceptions instead of Result pattern. Prefer the Result-returning filterAsync for better error handling.

Param​

Array of items to filter

Param​

Async function that returns true to keep the item

Param​

Concurrency options

Returns​

Promise resolving to filtered array

Throws​

FilterAsyncError if any predicate evaluation fails

Example​

// Throws on error
try {
  const existingUsers = await filterAsyncOrThrow(
    userIds,
    async (id) => {
      const res = await fetch(`/api/users/${id}`)
      return res.ok
    },
    { concurrency: 5 }
  )
} catch (error) {
  console.error('Filter failed:', error)
}
