Hello everyone yesterday i accidentally ripped out some smd diodes on my nodemcu board while soldering and now i can't power the board through the VIN pin and the usb input. I also can't upload any sketches because my computer doesn't recognise the board. However when i power the board via the 3v pin the esp8266 on the board works just fine and i can see the led blinking.
Shortly i can't upload code to the board via usb can i use an arduino to upload a sketch to the board?
Thanks.

Yes you can, with a similar method as one would do with an ESP-01, with the main difference being that the RX pin on the nodeMCU is 5v tolerant. So load a blank sketch onto the Arduino (or blink or something else as long as it doesn't use the Serial port or pin 0 & 1)
power the nodeMCU via 3.3v (an original Uno has enough power for an ESP-01, but i am not sure if it has enough for a nodeMCU, smaller boards like the nano can not power an ESP through their 3.3v output) connect GND <-> GND, TX <-> TX & RX <-> RX. Put your nodeMCU in flash(boot) mode, select the proper board and hit upload. I do suggest to set up OTA updates fairly soon if you are going to do a lot of development, it will be quite a lot easier.

Soldering what ? don't solder straight onto the board ! get some female header pins and create a shield for the board.
