fs

The fs helper provides functions for interacting with the file system within the MARS Engine environment.

fs.exists(path)

Returns true if the file exists.

if (fs.exists("data.csv")) {
  write("OK")
}

fs.loadFile(path)

Returns the file object.

The file object has three attributes:

• name - Representing the name of the file
• contentType - Representing the type of content
• data - Binary file content

const text = fs.loadFile("hello.txt")

fs.save(path, contents)

Writes string or buffer to a file. Overwrites if file exists.

fs.save("log.txt", "started")

fs.delete(path)

Deletes a file.

fs.delete("old.csv")
