Shared behavio Pure chat message, retry, memory, summary, and persona-state formatting lives in `src/services/chatMessageHelpers.js`; `chatService.js` remains responsible for orchestration and persistence. +## Optional Web Search + +The globe button next to the composer enables search for one message. It defaults to off and resets once the server accepts the message. The browser sends `webSearch: true` (or `false`) through the existing authenticated `POST /chat/stream`; `POST /chat` supports the same optional boolean. Omitting it preserves the normal chat flow. No generic tool/agent system is needed. + +The existing chat service saves the user message, performs one server-side SearXNG search using the current message (whitespace normalized, at most 500 characters), then supplies up to five numbered results as a separate context alongside the existing history, model, personas and generation settings. Instructions require numbered citations, acknowledgement of insufficient results and treating all result content as untrusted data. This is a basic prompt-injection precaution, not a guarantee that a model will follow instructions. No result pages are fetched. + +Set environment variables in the server/container environment, or load the example explicitly with `node --env-file=.env server.js` (the existing npm start command does not load `.env` automatically): + +```dotenv +SEARXNG_URL=http://searxng:8080 +WEB_SEARCH_TIMEOUT_MS=8000 +``` + +`SEARXNG_URL` is optional and server-only. It must be an HTTP(S) base URL reachable from Express, for example over the same Docker network. Use the final URL: redirects are rejected. Missing/invalid configuration leaves ordinary chat available and returns `Web search is currently unavailable.` for search requests. `WEB_SEARCH_TIMEOUT_MS` limits the whole search response, including body download (default 8000 ms). Responses are limited to 1 MiB; each source has at most a 300-character title, 2048-character URL and 1500-character snippet. Only HTTP(S) source links without embedded credentials are accepted. No user input can override the provider URL. + +Enable JSON in SearXNG's `settings.yml`: + +```yaml +search: + formats: + - html + - json +``` + +The provider calls `GET {SEARXNG_URL}/search?q=...&format=json` using encoded query parameters. SearXNG must allow requests from the application server; disabled JSON output returns HTTP 403. See the [official Search API documentation](https://docs.searxng.org/dev/search_api.html). Only the current query is sent to SearXNG, not conversation history or personas; configured SearXNG engines can forward that query to their search services. + +The server-side `WebSearchProvider` JSDoc contract is `search(query, {signal, limit}?) -> Promise`; `SearXNGSearchProvider` is the initial implementation. Results have `{title, url, snippet}`. This repository uses JavaScript ES modules, so types are documented with JSDoc rather than introducing a TypeScript build. + +Search adds SSE `status` events: `{status: "searching"}` after message acceptance and `{status: "generating", sourceCount}` before model generation. Existing `chunk` events are unchanged. `done` adds optional `sources` to `{reply}`; the non-streaming response does likewise. Empty results produce `sources: []` and an explicit insufficient-results instruction. Failures produce the existing error event (HTTP 503 on `/chat`); no model answer is generated after search failure. The saved failed user message remains visible, and the composer restores its text for resending without search. + +Sources appear below assistant messages as numbered links. They persist in a nullable SQLite `chat_messages.sources` JSON column, added automatically on startup using the existing additive schema mechanism; no manual migration is needed. Old messages remain valid. Sources are preserved in JSON exports/imports and branches. Regenerating an answer reuses its stored results without performing another search; a fresh search requires sending another message with the toggle enabled. + +Run `node --test --test-isolation=none` and `npm run lint` to check the feature and existing flows. `test/webSearch.test.js` uses local HTTP protocol fixtures and an isolated in-memory database; no production search results are mocked. Live SearXNG/Ollama verification still requires configured, reachable services. There is no TypeScript or build command in this framework-free project. + ## Legal - [Privacy Policy](PRIVACY_POLICY.md) diff --git a/public/app/api.js b/public/app/api.js index 7d96387..2427d81 100644 --- a/public/app/api.js +++ b/public/app/api.js @@ -58,6 +58,7 @@ export async function stream(url, data, handlers = {}) { const event = eventLine.slice(6).trim(); const payload = JSON.parse(dataLine.slice(5).trim()); if (event === "chunk" && handlers.onChunk) handlers.onChunk(payload); + if (event === "status" && handlers.onStatus) handlers.onStatus(payload); if (event === "done" && handlers.onDone) handlers.onDone(payload); if (event === "error" && handlers.onError) handlers.onError(payload); } diff --git a/public/app/webSearch.js b/public/app/webSearch.js new file mode 100644 index 0000000..58aae7d --- /dev/null +++ b/public/app/webSearch.js @@ -0,0 +1,52 @@ +/** @typedef {{title: string, url: string, snippet: string}} WebSource */ +/** @typedef {{message: string, model: string, chatId: number, webSearch?: boolean}} ChatRequest */ +/** @typedef {{role: string, content: string, sources?: WebSource[]}} ChatMessage */ + +export function createWebSearchToggle(button) { + let enabled = false; + const reset = () => { + enabled = false; + render(); + }; + const render = () => { + button.setAttribute("aria-pressed", String(enabled)); + button.title = enabled ?
