[Feature Proposal] Allow error property regex matching

[craigmichaelmartin]

Many times errors from 3rd parties are just of type Error and have to be inspected. What if we supported error property regex/string-matching? Thus:

In addition to:

const [data, duplicateError] = await fa(create(/*...*/), DuplicateError)

we would support

const [data, duplicateError] = await fa(create(/*...*/), {message: /^duplicate key/})

Which would match for this error:

Error {
    "name": "error",
    "length": 221,
    "severity": "ERROR",
    "code": "23505",
    "detail": "Key (line_item_id)=(12345) already exists.",
    "schema": "public",
    "table": "review",
    "constraint": "review_line_item_id_key",
    "message": "duplicate key value violates unique constraint \"review_line_item_id_key\""
}

This would also work

const [data, duplicateError] = await fa(create(/*...*/), {constraint: 'review_line_item_id_key'})

This regex/string matching of error property should also work for N-levels. If the error was of type DuplicateError, these would be equivalent:

const [data, duplicateError] = await fa(create(/*...*/), DuplicateError)
const [data, duplicateError] = await fa(create(/*...*/), {constructor: {name: 'DuplicateError'}})

This would also be supported in the alternate API of allowing the errors to be in an array.

Requirements:

• Property matching of error by regex or string
• Property matching supports N-levels deep of matching
• This is supported in the alternate API
• Tests for all of these things
