Data#

Overview#

Filesystem access endpoints scoped to the configured dataDir. Used by MappingModeler and the CSV picker to browse, read, write, and delete files in a sandboxed area of the server.

All sensitive operations sanitize paths to prevent directory traversal, and DELETE on a file checks readwrite access on the optional source parameter.

Modules#

1. Listing (files.js)#

Lists file names inside dataDir/<dir> (dataController.getFilesList).

2. File CRUD (file.js)#

  • GET reads the parsed content of dataDir/<dir>/<fileName>.

  • POST overwrites/creates the file with the body’s data payload.

  • DELETE removes the file, with optional readwrite check against a source.

3. CSV preview (csv.js)#

Streams the first N lines of a CSV file as JSON rows for quick preview in the UI.

4. Directory creation (dir.js)#

Creates a new sub-directory under dataDir.

Files in this directory#

  • csv.js

  • dir.js

  • file.js
