i have created secretjs.js with browserify but when i trying to connect to node i get:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at [https://api.secretapi.io/node\_info](https://api.secretapi.io/node_info). (Reason: CORS request did not succeed)
the code i use is
> const main = async () =\> {
> // Create connection to DataHub Secret Network node
> const client = new secretjs.CosmWasmClient(‘[https://api.secretapi.io/](https://api.secretapi.io/)’)
>
> ```
> // Query chain ID
> const chainId = await client.getChainId()
>
> // Query chain height
> const height = await client.getHeight()
>
> console.log("ChainId:", chainId);
> console.log("Block height:", height);
>
> console.log('Successfully connected to Secret Network');
>
> ```
>
> }
>
> main().then(resp =\> {
> console.log(resp);
> }).catch(err =\> {
> console.log(err);
> })
what i can do?

Hi guys, please checkout [GitHub - scrtlabs/secret.js: The JavaScript SDK for Secret Network](https://github.com/scrtlabs/secret.js)
CORS errors is something that you need to sort out with your node provider.

Ok i give up, what i trying to achieve is simply check wallet balance with javascript to do so i trying to use this code:
> const main = async () =\> {
> // Create connection to DataHub Secret Network node
> console.log(‘before connection’);
> const client = new secretjs.CosmWasmClient(‘[http://chainofsecrets.secrettestnet.io:26657/](http://chainofsecrets.secrettestnet.io:26657/)’)
>
> console.log(‘after connection’);
> // Query chain ID
> const chainId = await client.getChainId()
>
> ```
> // Query chain height
> const height = await client.getHeight()
> console.log(walletAddress);
> const account = await client.getAccount(walletAddress);
>
> console.log("ChainId:", chainId);
> console.log("Block height:", height);
> console.log("Account", account);
>
> console.log('Successfully connected to Secret Network');
>
> ```
>
> }
>
> main().then(resp =\> {
> console.log(resp);
> }).catch(err =\> {
> console.log(err);
> })
i have tried every RPC url i can find on internet the only that worked was :[http://bootstrap.supernova.enigma.co:1317](http://bootstrap.supernova.enigma.co:1317)
but this one for testnet. Where i can find mainnet RPC node url? Thanks!

With that version of secretjs you need to use the LCD endpoint, you got one in your figment account
