Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
@codama/validators
Advanced tools
This package offers a set of validation rules for Codama IDLs to ensure that they are correctly formatted.
pnpm install @codama/validators
[!NOTE] This package is included in the main
codama
package. Meaning, you already have access to its content if you are installing Codama this way.pnpm install codama
ValidationItem
A validation item describes a single piece of information — typically a warning or an error — about a node in the Codama IDL.
type ValidationItem = {
// The level of importance of a validation item.
level: 'debug' | 'trace' | 'info' | 'warn' | 'error';
// A human-readable message describing the issue or information.
message: string;
// The node that the validation item is related to.
node: Node;
// The path of nodes that led to the node above (including the node itself).
path: NodePath;
};
getValidationItemsVisitor(visitor)
The getValidationItemsVisitor
function returns a visitor that collects all validation items from a Codama IDL. Note that this visitor is still a work in progress and does not cover all validation rules.
import { getValidationItemsVisitor } from '@codama/validators';
const validationItems = codama.accept(getValidationItemsVisitor());
throwValidatorItemsVisitor(visitor)
The throwValidatorItemsVisitor
function accepts a Visitor<ValidationItemp[]>
and throws an error if any validation items above a certain level are found. By default, the level is set to 'error'
but a second argument can be passed to change it.
import { throwValidatorItemsVisitor, getValidationItemsVisitor } from '@codama/validators';
// Throw if any "error" items are found.
codama.accept(throwValidatorItemsVisitor(getValidationItemsVisitor()));
// Throw if any "warn" or "error" items are found.
codama.accept(throwValidatorItemsVisitor(getValidationItemsVisitor(), 'warn'));
