+# ds-docservice-dev.conf — DEVELOPMENT: editor served 100% from SOURCE (/develop)
+#
+# Replicates ONLYOFFICE's official "developer mode" (build_tools/develop): api.js, web-apps and
+# sdkjs are served from the SOURCE tree, mutually coherent, instead of mixing compiled pieces
+# (the root cause of the "Asc is not defined" and "R_ null" errors).
+#
+# Key points:
+#  - The SOURCE api.js keeps the {{PRODUCT_VERSION}} placeholder -> DocsAPI (extendAppPath,
+#    api.js:1327) does NOT add the /X.Y.Z-<hash>/ version prefix -> the editor loads from
+#    /web-apps/... unversioned and the SDK load order (synchronous document.write -> RequireJS)
+#    works as ONLYOFFICE designed it.
+#  - SDK served from /develop/sdkjs with the real develop loader (grunt develop) + AllFonts.js ->
+#    coherent with the front. Falls back to $EO_ROOT for generated binaries (.wasm, theme.bin)
+#    that are not present in the source tree.
+#  - Service worker neutralised + auto live-reload (livereload proxied through :8080).
+#
+# One-time requirement: the SDK develop loader in the source tree (make sdkjs-dev) and AllFonts.js
+# under /develop/sdkjs/common. Toggle with: make front-dev / front-dev-live / front-prod.
+# Docs: https://docs.euro-office.com/development/hot-reload/
+#
+# MAINTENANCE: the access-controlled tail of this file (cache/files secure_link, internal,
+# info, versioned passthrough) mirrors the production ds-docservice.conf shipped in the image.
+# If that production config changes (e.g. an access-control fix), mirror it in the blocks below.

+// Live-reload server for front hot-reload (source mode).

+// so we detect changes by polling mtimes.
+const livereload = require('livereload');
+
+// Polling cost: chokidar in polling mode stat()s every watched file on each tick, and
+// web-apps/apps holds ~20k files. So we (a) poll at 1s rather than 500ms — halving the
+// stat load on the WSL/9p mount — and (b) exclude heavy trees that are never hand-edited
+// during UI iteration (third-party vendor bundles, minified files, source maps, build
+// output). "save -> reload" stays ~1-2s. Lower `interval` only if you have spare CPU.
