The legacy outbound modal could import a vmess://, vless://, trojan://,
ss://, or hysteria2:// share link via a Convert button on the JSON
tab. Restore that UX with a focused pure-function parser.
lib/xray/outbound-link-parser.ts:
- parseVmessLink: base64 JSON, maps net/tls + per-network params onto
the discriminated stream branch.
- parseVlessLink: standard URL with type/security/sni/pbk/sid/fp/flow
query params, dispatches transport via buildStream + applies
security params via applySecurityParams.
- parseTrojanLink: same URL pattern, defaults security to tls.
- parseShadowsocksLink: both modern (base64 userinfo@host:port) and
legacy (base64 of whole thing) ss:// formats.
- parseHysteria2Link: accepts both hysteria2:// and hy2:// schemes,
uses the hysteria stream branch with version=2 + TLS h3.
- parseOutboundLink dispatcher returns the first non-null parser
result, or null when no scheme matches.
test/outbound-link-parser.test.ts:
- 13 cases covering happy paths for each protocol family plus malformed
input, ss:// dual-format handling, hy2:// alias.
OutboundFormModal.tsx:
- Import button on the JSON tab Input.Search; on success, parsed
payload flows through rawOutboundToFormValues, the form is reset,
and we switch back to the Basic tab.
- Tag is preserved when the parsed link does not carry one.
Out of scope: advanced fields the legacy parser handled (xmux, padding
obfs, reality short IDs, finalmask from fm= param). Power users can
finish the import in the form after the basics land.
