Node.js EOL Versions CVE Dubbed the "Worst CVE of the Year" by Security Experts
Critics call the Node.js EOL CVE a misuse of the system, sparking debate over CVE standards and the growing noise in vulnerability databases.
@terra-money/amino-js
Advanced tools
amino-js
Supported in Node.js and browsers.
Support is planned for Service Workers.
https://cosmos.github.io/amino-js/
All exported functions are documented. Some Amino registered TypeScript interfaces are documented. The codec works as is, but we'll work on adding more TS definitions to improve the developer experience.
Please note that the NPM package name is @tendermint/amino-js
rather than @cosmos/amino-js
.
yarn add @tendermint/amino-js
npm install @tendermint/amino-js
Encoding decoding of basic values:
import { encodeString, decodeString } from '@tendermint/amino-js';
decodeString(encodeString('hello world'));
// [ "hello world", 12 ]
Encoding/decoding of registered types:
import { marshalTx, unmarshalTx } from '@tendermint/amino-js';
const tx = {
'type': 'auth/StdTx',
'value': {
'msg': [{
'type': 'pay/MsgSend',
'value': {
'from_address': 'cosmos1h806c7khnvmjlywdrkdgk2vrayy2mmvf9rxk2r',
'to_address': 'cosmos1z7g5w84ynmjyg0kqpahdjqpj7yq34v3suckp0e',
'amount': [{
'denom': 'uatom',
'amount': '11657995'
}]
}
}],
'fee': {
'amount': [{
'denom': 'uatom',
'amount': '5000'
}],
'gas': '200000'
},
'signatures': [{
'pub_key': {
'type': 'tendermint/PubKeySecp256k1',
'value': 'AtQaCqFnshaZQp6rIkvAPyzThvCvXSDO+9AzbxVErqJP'
},
'signature': '1nUcIH0CLT0/nQ0mBTDrT6kMG20NY/PsH7P2gc4bpYNGLEYjBmdWevXUJouSE/9A/60QG9cYeqyTe5kFDeIPxQ=='
}],
'memo': '1122672754'
}
};
const encodedTx = marshalTx(tx);
const decodedTx = unmarshalTx(encodedTx);
To register your own types with Amino, you'll need to add Go structs and interfaces, register them with the codec, compile the Go code with GopherJS, and then rebuild the JS lib.
To keep the compiled output small, the recommended way to do this is to add your Go structs, but strip out methods, private properties, and anything else that you don't plan to marshal to Amino.
This is all (hopefully) less complicated than it sounds.
