so i have shared the it's schematic and board design with the eevblog.com community and they said "that this module will not work and the relay contacts and board tracks can't handle high current" I improved and made the board anyway and tested it with inductive and resistive loads and it works without a problem huh

The manufacturer has rated this relay for nominal motor (ie inductive) loads of 0.5 A, with peak surge of 2.5 A, at 120 VAC. The flyback diode should be sufficient, since the switching rate would not be very high to control a relay. The terminal block supports a max wire diameter of 1.5mm2 (~16 AWG) which would be more than plenty for a 0.5 A load.

If you're actually running >60 VAC through the relay, then it's good practice to add a slot that prevents creepage currents between the low-voltage DC section and the higher-voltage power section.

For smaller applications, this seems reasonable enough, at least to me.

for 240V AC this relay can handle 5 Amps
