Basic usage

To start a file server, do:

srv := NewFileServer("/my-files", "mySecretCode")
err := http.ListenAndServe(":8080", srv)
if err != nil {
    panic(err)
}

Now we want to create a file that we can write to remotely:

file, err := os.CreateTemp(os.TempDir(), "New Test File.txt")
assert.NoError(t, err)
defer func() {
    _ = file.Close()
}()

ctx, cancelFn := context.WithTimeout(context.Background(), time.Minute)
defer cancelFn()

err = srv.ServeFileWriter(ctx, fileID, dst)
if err != nil {
    panic(err)
}

Then on the client side, we open a writer for this file:

ctx, cancelFn := context.WithTimeout(context.Background(), time.Minute)
defer cancelFn()

wrtr := NewWriter(ctx, "http://my-file-server:8080/my-files", "mySecretCode", fileID)
_, err := wrtr.Write([]byte("Hello, World!"))
if err != nil {
    panic(err)
}
err = wrtr.Close()
if err != nil {
    panic(err)
}
