How to add a new network that is not already listed? about dappeteer

[Vxatz]

Seems like there had previously been a .addNetwork() method, but for some reason, it was deprecated.

Is there an alternative?

@Vxatz there doesn't seem to be an alternative from the API documentation

Seems like there had previously been a .addNetwork() method, but for some reason, it was deprecated.

Historically we have a lot of issues with adding a network over a MetaMask UI, and this feature is actually not so important for dapp dev as he needs to use EIP-3085 for better UX

Is there an alternative?

For an alternative, you can reference this test

dappeteer/test/basic.spec.ts

Lines 133 to 138 in a41e6dd

	it("should add network and switch", async function (this: TestContext) {
	const addNetworkPromise = testPage.evaluate(addNetwork);
	await metaMask.acceptAddNetwork();
	const res = await addNetworkPromise;
	expect(res).to.equal(true);
	});

that simple usage evaluation with EIP-3085

dappeteer/test/testPageFunctions/addNetwork.ts

Lines 1 to 27 in a41e6dd

	export const addNetwork = async (): Promise<boolean> => {
	const addNetworkRequest = window.ethereum.request<boolean>({
	method: "wallet_addEthereumChain",
	params: [
	{
	chainId: "0xa",
	chainName: "Optimism",
	nativeCurrency: {
	name: "ETH",
	symbol: "ETH", // 2-6 characters long
	decimals: 18,
	},
	rpcUrls: ["https://mainnet.optimism.io"],
	},
	],
	});
	return new Promise((resolve) => {
	addNetworkRequest
	.then(() => {
	resolve(true);
	})
	.catch(() => {
	resolve(false);
	});
	});
	};
