Using Public Nodes in IOTA Tangle for testing purpose

Question

I want to send some string data using MAM over IOTA Tangle. Right now, I am using devnet. I want to know how can we test our transactions using public nodes on Mainnet? What is the process for it? I could not seem to find any instructions on how to set up public node to pass transaction using MAM. Any leads would be highly appreciated.

You can change the URL in the provider field to a node that's on the Mainnet.

You can use this URL as an example: https://nodes.thetangle.org/

Or, you can run your own node.

Be sure to use a minimum weight magnitude of at least 14 for the Mainnet.

For example, for the code you linked to, you need to use something like the following:

const provider = 'https://nodes.thetangle.org/';
await Mam.attach(message.payload, message.address, 3, 14 /*this is the minimum weight magntiude*/)
