The cosmwasmjs's discuss from cosmwasm

global is not defined

I created a new vue project, when I execute the content in the readme

Remove StargateClient, SigningStargateClient,

Those are not the focus of this project

publish update?

There's been a lot of updates since the last release, including pretty core functionality like executeMultiple()

Gentle reminder to release with upgraded deps :)

(my use case for this isn't so much the stated goal of the Readme which is "to help new developers get started with their first dApps", but rather to import the JS needed in a project that loads the JS via regular script tag and doesn't have a bundler)

Subscribe/Listen to contract events

I have cosmwasm smart contracts on the Osmosis side chain. I want to be able to interact with the contract from my Javascript application using the contract abi. the docs provide a way to query the read only methods using the CosmWasm client, but I don't see a way to instantiate the contract in my Javascript app using the abi and listen or subscribe to events emitted by the contract.

Please help or point to the right docs that helps me does this.

Add encoding functions

Create UMD module and add as installation method to docs

Having an UMD module allows web developers to get started with a plain HTML page and a script tag. No bundler needed. Since we have a single package here (in conntrast to CosmJS), it would be great to try this out.

This has been requested at cosmos/cosmjs#998. Also Terra.js in the browser shows how this can be offered to the user. Being able to use CosmWasmJS in a jsfiddle seems like an interesting opportunity we get with this.

Roll out exported symbols in index.ts

It would be great to have all exported symbols of the package visible in one file. For this, can we make the *s in

CosmWasmJS/src/index.ts

Lines 1 to 13 in a2a013a

    
           /** 
        
            * Exporting all the defined CosmJS symbols 
        
            */ 
        
           export * from "./amino"; 
        
           export * from "./cosmwasm-stargate"; 
        
           export * from "./crypto"; 
        
           export * from "./encoding"; 
        
           export * from "./faucet-client"; 
        
           export * from "./ledger-amino"; 
        
           export * from "./math"; 
        
           export * from "./proto-signing"; 
        
           export * from "./stargate"; 
        
           export * from "./utils";

explicit?

Maybe we should remove all the .ts files that only re-export CosmJS types and do that in the main index file directly.

Change marketing-friendly spelling to CosmWasmJS

What are RPC endpoints for testnet and mainnet?

basic example in docs goes:

const rpcEndpoint = "https://rpc.cliffnet.cosmwasm.com:443/";

async function main() {
  const client = await CosmWasmClient.connect(rpcEndpoint);
  console.log(client);
}

I've tried to log const height = await client.getBlock() and got 386,152.

According to https://gaia.bigdipper.live , block height of stargate-final (testnet) is 2,832,763 and https://cosmos.bigdipper.live shows 9,506,024 for cosmoshub-4 mainnet. What am I missing? What's this "386,152"?

What endpoint should I use for testnet? For mainnet? I've found that https://stargate.cosmos.network/testnet states that public RPC endpoint is 34.71.170.158:26657. I've tried both const rpcEndpoint = "http://34.71.170.158:26657/"; and https version and got Error: connect ECONNREFUSED 34.71.170.158:26657 for each.

Remove unused bufferutil dependency

bufferutil pulls in node-gyp-build, which is for building native code. Most likely we don't want any of those in here.

It was added in #27. Was that on purpose?

Error: Invalid string. Length must be a multiple of 4

Summary of the bug

We try to use the newest CosmWasmJS (1.1.1) to connect to newest Wasmd (taken from main branch). Transaction gets committed successfully on chain but as a response we get this error in the client:

/Users/msedzinski/git/client/node_modules/base64-js/index.js:26 
[1]     throw new Error('Invalid string. Length must be a multiple of 4')

I think the error is related to those issues (already closed):
cosmos/cosmos-sdk#11997
ping-pub/faucet#4

Solution, mentioned there, is to update cosmjs client.

Are there any plans to do that anytime soon?

Versions

CosmWasmJS 1.1.1
Wasmd - main branch
CosmJS - 0.28 (which seems to be to old)

Steps to reproduce

Run Wasmd
Generate transaction from CosmWasmJS that emits event
Error happens each time

const rpcEndpoint = "https://rpc.cosmos.network/";
const client = CosmWasmClient.connect(rpcEndpoint);
const someAddressFromMainnet = "cosmos1l0znsvddllw9knha3yx2svnlxny676d8ns7uys";
const txs = await client.searchTx({
    sentFromOrTo: someAddressFromMainnet,
});

Explorer shows that the account exists and has participated a number of txs, but I'm getting the 502 error.

Is it me doing something wrongly or CosmWasmJS/mainnet public RPC/explorer's problem?
