# CosmJS
|
||||
|
||||
This is a JavaScript/TypeScript client-side binding to [wasmd](https://github.com/cosmwasm/wasmd), a sample blockchain for the [cosmwasm](https://github.com/confio/cosmwasm) smart contracting platform.
|
||||
CosmJS is the Swiss Army knife to power JavaScript based client solutions
|
||||
ranging from Web apps/explorers over browser extensions to server-side clients
|
||||
like faucets/scrapers in the Cosmos ecosystem.
|
||||
|
||||
"Cosm" is short for Cosmos and "JS" is short for _runs everywhere_ – we actually
|
||||
develop in TypeScript.
|
||||
|
||||
## Packages
|
||||
|
||||
CosmJS is a library that consists of many smaller npm packages within the
|
||||
[@cosmjs namespace](https://www.npmjs.com/org/cosmjs), a so called monorepo.
|
||||
Here are some of them to get an idea:
|
||||
|
||||
| Package | Description | Latest |
|
||||
| ------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- |
|
||||
| [@cosmjs/sdk38](packages/sdk38) | A client library for the Cosmos SDK 0.38 | [](https://www.npmjs.com/package/@cosmjs/sdk38) |
|
||||
| [@cosmjs/faucet](packages/faucet) | A faucet application for node.js | [](https://www.npmjs.com/package/@cosmjs/faucet) |
|
||||
| [@cosmjs/cosmwasm](packages/cosmwasm) | Client for chains with the CosmWasm module enabled | [](https://www.npmjs.com/package/@cosmjs/cosmwasm) |
|
||||
| [@cosmjs/crypto](packages/crypto) | Cryptography for blockchain projects, e.g. hashing (SHA-2, Keccak256, Ripemd160), signing (secp256k1, ed25519), HD key derivation (BIPO39, SLIP-0010), KDFs and symmetric encryption for key storage (PBKDF2, Argon2, XChaCha20Poly1305) | [](https://www.npmjs.com/package/@cosmjs/crypto) |
|
||||
| [@cosmjs/encoding](packages/encoding) | Encoding helpers for blockchain projects | [](https://www.npmjs.com/package/@cosmjs/encoding) |
|
||||
| [@cosmjs/math](packages/math) | Safe integers; decimals for handling financial amounts | [](https://www.npmjs.com/package/@cosmjs/math) |
|
||||
|
||||
### Modularity
|
||||
|
||||
We're pretty proud of the modularity and a clean dependency tree in this
|
||||
monorepo. This ensures software quality on our side and lets users pick exactly
|
||||
what they need. Here you see how everything fits together (every item is a npm
|
||||
package; right depends on left):
|
||||
|
||||
|
||||
|
||||
<!--
|
||||
Build with depsight (https://github.com/webmaster128/depsight), using:
|
||||
|
||||
from_npm ~/cosmjs | depsight --exclude cosmjs-monorepo-root --format svg --output - | inkscape --pipe --export-width 3000 --export-filename cosmjs-tree.png
|
||||
|
||||
optipng cosmjs-tree.png
|
||||
-->
|
||||
|
||||
### Supported JS environments
|
||||
|
||||
Currently the codebase supports the following runtime environments:
|
||||
|
||||
1. Node.js 10+
|
||||
2. Modern browsers (Chromium/Firefox/Safari, no Internet Explorer or
|
||||
[Edge Spartan](https://en.wikipedia.org/wiki/Microsoft_Edge#Development))
|
||||
3. Browser extensions (Chromium/Firefox)
|
||||
|
||||
Our current JavaScript target standard is ES2017, giving us native async/await
|
||||
support. We use WebAssembly to implement certain cryptographic functions.
|
||||
|
||||
We're happy to adjust this list according to users' needs as long as you don't
|
||||
ask for Internet Explorer support. If your environment does not support Wasm, we
|
||||
can work on a solution with swapable implementations.
|
||||
|
||||
## Development
|
||||
|
||||
Requires Node 10+. For best results, use yarn. The basic commands are:
|
||||
|
||||
```sh
|
||||
yarn install
|
||||
|
||||
# compile the code
|
||||
yarn build
|
||||
# run unit tests

||||

|

|
||||
### Integration tests
|
||||
|
||||
To run the entire test suite, you need to run a local blockchain to test against. This should work on any Linux/OSX system with docker installed.

### Staking via OpaqueMsg
|

|

And now... let's use `OpaqueMsg` to call into native blockchain messages.
|
||||
Here we will trigger a staking command. This is an "opaque" command, so neither cosmwams-js
|
||||
nor the cosmwasm contract understands it. It is passed verbatim from the client to
|
||||
the wasmd blockchain (reflected by mask, so using the mask address).

We plan to add custom types for some popular native messages to make this binding simpler,

## Transfering Owner
|

Happy hacking using the mask contract. And to make this a bit more interesting, note that you can transfer

control of this mask. By transfering ownership, we transfer control of our `ucosm` native , our `FOO` erc20 token,
|
||||
and our open staking position in one fell swoop, without the other modules/contracts being aware of the change.
