From 117e5924fd5c94ebce0e155ac989abccb10cf80b Mon Sep 17 00:00:00 2001 From: mleku Date: Wed, 22 Oct 2025 11:37:39 +0100 Subject: [PATCH] Remove deprecated JSON encoder/decoder and update dependencies - Deleted the custom JSON encoder/decoder implementation in favor of the standard library's `encoding/json` package. - Removed the `next.orly.dev/pkg/encoders/json` package and its associated files. - Updated `go.mod` to remove the `github.com/nostr-dev-kit/ndk` dependency and bump the version of `lol.mleku.dev` from v1.0.3 to v1.0.4. - Cleaned up import statements across various files to reflect the removal of the custom JSON package. - Ensured that all references to the old JSON encoding/decoding methods are replaced with the standard library equivalents. --- app/payment_processor.go | 3 +- go.mod | 1 -

In particular the following -// parsing behaviors may cause issues: -// -// - If a JSON object contains duplicate keys, keys are processed in the order -// they are observed, meaning later values will replace or be merged into -// prior values, depending on the field type (in particular maps and structs -// will have values merged, while other types have values replaced). -// - When parsing a JSON object into a Go struct, keys are considered in a -// case-insensitive fashion. -// - When parsing a JSON object into a Go struct, unknown keys in the JSON -// object are ignored (unless a [Decoder] is used and -// [Decoder.DisallowUnknownFields] has been called). -// - Invalid UTF-8 bytes in JSON strings are replaced by the Unicode -// replacement character. -// - Large JSON number integers will lose precision when unmarshaled into -// floating-point types. -package json - -import ( - "bytes" - "cmp" - "encoding" - "encoding/base64" - "fmt" - "math" - "reflect" - "slices" - "strconv" - "strings" - "sync" - "unicode" - "unicode/utf8" - _ "unsafe" // for linkname -) - -// Marshal returns the JSON encoding of v. -// -// Marshal traverses the value v recursively. -// If an encountered value implements [Marshaler] -// and is not a nil pointer, Marshal calls [Marshaler.MarshalJSON] -// to produce JSON. If no [Marshaler.MarshalJSON] method is present but the -// value implements [encoding.TextMarshaler] instead, Marshal calls -// [encoding.TextMarshaler.MarshalText] and encodes the result as a JSON string. -// The nil pointer exception is not strictly necessary -// but mimics a similar, necessary exception in the behavior of -// [Unmarshaler.UnmarshalJSON]. -// -// Otherwise, Marshal uses the following type-dependent default encodings: -// -// Boolean values encode as JSON booleans. -// -// Floating point, integer, and [Number] values encode as JSON numbers. -// NaN and +/-Inf values will return an [UnsupportedValueError]. -// -// String values encode as JSON strings coerced to valid UTF-8, -// replacing invalid bytes with the Unicode replacement rune. -// So that the JSON will be safe to embed inside HTML
