Code Review
This pull request introduces the Arox Framework, a new foundation for building Discord bots, featuring a well-organized structure with a builder pattern for commands and events, i18n support, and a comprehensive build and release process. However, several utility scripts used for building and releasing the package are vulnerable to command injection. These scripts construct shell commands using string interpolation with variables from package.json, posing a risk of arbitrary command execution in build or CI environments. Additionally, the review highlights design concerns regarding global mutable state for the client instance, and suggests improvements for error handling, TypeScript compiler settings, and naming conventions.

The createRelease function is vulnerable to command injection. It constructs a shell command string by interpolating the version and assetPath variables. An attacker could inject shell metacharacters into the version field of package.json to execute arbitrary commands. Although the developer attempted to prevent injection for the release notes by using stdin, the version and assetPath parameters remain unprotected. It is recommended to use execFileSync and pass arguments as an array to avoid shell interpretation.
import { execFileSync } from "node:child_process";
export function createRelease(version, tgzPath, body = "") {
const sha = getSha();
console.log(`Creating GitHub Release & Tag: ${version}`);
const prereleaseFlag = isPrerelease(version) ? "--prerelease" : null;
const notes = body || `Release ${version}`;
const assetPath = tgzPath ? path.resolve(tgzPath) : "";
const args = [
"release",
"create",
version,
assetPath,

The checkVersionExists function is vulnerable to command injection. It uses string interpolation to build an npm view command, where packageName and version variables are sourced from package.json. This creates a potential vector for command injection in the build environment. To mitigate this, it is recommended to use a safer execution method that doesn't involve the shell, such as execFileSync with an arguments array.
import { execFileSync } from "node:child_process";
export function checkVersionExists(packageName, version, registry) {
try {
execFileSync("npm", ["view", `${packageName}@${version}`, "--registry", registry], {
stdio: "ignore"
});
return true;
} catch {
return false;

| }); |

The tagExists function is vulnerable to command injection because it interpolates the tag variable directly into a shell command string. Since tag is derived from the version field in package.json, an attacker who can modify package.json (e.g., via a pull request) could execute arbitrary commands in the build/CI environment.
import { execFileSync } from "node:child_process";
export function tagExists(tag) {
try {
execFileSync("gh", ["api", `repos/${process.env.GITHUB_REPOSITORY}/git/ref/tags/${tag}`], {
stdio: "ignore",
});
return true;
} catch {
return false;

The npm publish command is constructed using string interpolation with the tarballPath and tagArg variables. If these variables contain shell metacharacters, it could lead to command injection. While tarballPath is currently generated in a temporary directory, tagArg is derived from the version in package.json. It is safer to pass arguments as an array to avoid shell interpretation.
import { execFileSync } from "node:child_process";
const distTag = getNpmDistTag(version);
const args = ["publish", tarballPath, "--registry", GITHUB_URL];
if (distTag !== "latest") {
args.push("--tag", distTag);
}

Similar to the GitHub release script, the npm publish command here is vulnerable to command injection via string interpolation of tarballPath and tagArg. Using execFileSync with an array of arguments is the recommended remediation.
import { execFileSync } from "node:child_process";
const distTag = getNpmDistTag(version);
const args = ["publish", tarballPath, "--provenance", "--registry", NPM_URL];
if (distTag !== "latest") {
args.push("--tag", distTag);
}
execFileSync("npm", args, {
stdio: "inherit",

| void init(); |

The init function is async but is called without handling potential promise rejections (void init()). If client.login(token) fails, this will result in an unhandled promise rejection, which can crash the Node.js process.
It's safer to handle potential errors, even in an example file.
| void init(); | |
| init().catch((error) => { | |
| console.error("Failed to initialize client:", error); | |
| process.exit(1); | |
| }); |

| toJSON() { |
There was a problem hiding this comment.
The method name toJSON is a bit misleading. Conventionally, toJSON methods return a value that is serializable to a JSON string. However, this method returns an object that includes a function (t), which is not serializable. This could be confusing for developers using the class.
Consider renaming it to something that better reflects its purpose, such as asPayload() or getContextPayload().

| asPayload() { |
| ) { | ||
| return new Promise<void>((r) => { | ||
| setTimeout(() => { | ||
| message.delete().catch(() => {}); |
There was a problem hiding this comment.
The .catch(() => {}) swallows any errors that might occur when trying to delete a message. For example, if the message was already deleted by a user or another process, an error would be thrown and silently ignored. This can make debugging difficult.
It's better to at least log the error to the console for visibility during development.
| message.delete().catch(() => {}); | |
| message.delete().catch(console.warn); |

The compiler options noUnusedLocals and noUnusedParameters are currently disabled. Enabling them helps maintain code quality by flagging dead code and unused variables, which can prevent bugs and improve readability.
I recommend enabling these options. For intentionally unused variables, you can prefix them with an underscore (e.g., _variableName) to signal intent and satisfy the compiler.

There was a problem hiding this comment.
The verbatimModuleSyntax option is set to false. The modern recommended setting for new projects is true. It enforces that your import statements are emitted as-is, which prevents certain classes of bugs related to module interoperability between CommonJS and ES modules, and makes the code's module-related behavior more predictable.
