Filesystem + Web File Editor (/edit)

The library serves static files from the filesystem and, optionally, includes a web editor (ACE) to manage files directly from the browser.

Static file serving

By default, files are served from the filesystem with:

  • root URL / -> filesystem path /
  • default file: index.htm

In code (internally):

  • serveStatic("/", fs, "/").setDefaultFile("index.htm")

Stampa contenuto filesystem (debug)

Print filesystem contents (debug)

server.printFileList(FILESYSTEM, "/", 1);           // default -> Serial
server.printFileList(FILESYSTEM, "/", 1, Serial);  // or to a chosen stream

The Print& overload is useful to log to streams other than Serial.

Enable /edit

server.enableFsCodeEditor();

Main endpoints:

  • GET /edit editor page
  • GET /list?dir=/ directory listing
  • POST /edit upload
  • PUT /edit create/rename
  • DELETE /edit delete

Provide filesystem info (recommended on ESP32)

On ESP32, to show correct “total/used bytes” in the UI:

server.setFsInfoCallback([](fsInfo_t* fsInfo) {
  fsInfo->fsName = "LittleFS";
  fsInfo->totalBytes = LittleFS.totalBytes();
  fsInfo->usedBytes = LittleFS.usedBytes();
});
