⚡ Key issues to review Unused Import The LogLevel import from @slack/bolt package is removed, but customLogger is still being used. Ensure that customLogger is properly defined and imported if it's still needed. Error Handling The catch blocks for axios requests are missing the error parameter. This may lead to undefined behavior when trying to log errors. Inconsistent Error Handling Some functions (e.g., createServer) return early on error, while others (e.g., deleteServer) continue execution. Consider standardizing error handling across all functions.

PR Code Suggestions ✨

Category	Suggestion	Score
Performance	Add a timeout to API requests to prevent hanging Consider adding a timeout to the Axios requests to prevent hanging in case of slow or non-responsive API. This can improve the overall reliability of the application. command-handler/src/util/hetzner-servers.js [57-78] await axios.post('https://api.hetzner.cloud/v1/servers', { "automount": false, "image": image, "labels": { "owner": userEmail }, "location": region, "name": serverName, "public_net": { "enable_ipv4": true, "enable_ipv6": false }, "server_type": serverType, "start_after_create": true, "user_data": userData }, { headers: { 'Authorization': `Bearer ${process.env.HETZNER_API_TOKEN}`, 'Content-Type': 'application/json' - } + }, + timeout: 10000 // 10 seconds timeout }); Apply this suggestion Suggestion importance[1-10]: 10 Why: Adding a timeout to Axios requests is a crucial improvement that prevents the application from hanging due to slow or non-responsive APIs, significantly enhancing the application's reliability.	10
Error handling	Improve error handling by using specific error types in catch blocks Consider using a more specific error type in the catch block for the Axios request. This will allow for more precise error handling and logging. command-handler/src/util/hetzner-servers.js [79-89] -} catch { - log.error('There was an error creating the server', axiosError(error)); +} catch (error) { + if (axios.isAxiosError(error)) { + log.error('There was an error creating the server', axiosError(error)); + } else { + log.error('Unexpected error creating the server', error); + } app.client.chat.postEphemeral({ channel: `${body.channel.id}`, user: `${body.user.id}`, text: `Failed to create a server in hetzner.` }); return; } Apply this suggestion Suggestion importance[1-10]: 9 Why: The suggestion to use specific error types in catch blocks enhances error handling by distinguishing between Axios errors and other types of errors, leading to more precise logging and debugging.	9
Maintainability	✅ Improve string formatting using template literals for multiline strings Suggestion Impact: The suggestion to use template literals for the userData string was implemented, improving readability and maintainability by allowing easier multiline string formatting. code diff: -const userData = `#cloud-config\nruncmd:\n \ - - ['sh', '-c', 'curl -fsSL https://tailscale.com/install.sh | sh']\n \ - - ['tailscale', 'up', '--authkey=${process.env.TAILSCALE_AUTH_KEY}']\n \ - - ['tailscale', 'set', '--ssh']\n \ - - ['tailscale', 'set', '--accept-routes']\n \ - - ['passwd', '-d', 'root']` +const userData = ` +#cloud-config +runcmd: + - ['sh', '-c', 'curl -fsSL https://tailscale.com/install.sh | sh'] + - ['tailscale', 'up', '--authkey=${process.env.TAILSCALE_AUTH_KEY}'] + - ['tailscale', 'set', '--ssh'] + - ['tailscale', 'set', '--accept-routes'] + - ['passwd', '-d', 'root'] +` Consider using template literals for the userData string to improve readability and maintainability. This will also allow for easier multiline string formatting. command-handler/src/util/hetzner-servers.js [19-24] -const userData = `#cloud-config\nruncmd:\n \ - - ['sh', '-c', 'curl -fsSL https://tailscale.com/install.sh | sh']\n \ - - ['tailscale', 'up', '--authkey=${process.env.TAILSCALE_AUTH_KEY}']\n \ - - ['tailscale', 'set', '--ssh']\n \ - - ['tailscale', 'set', '--accept-routes']\n \ - - ['passwd', '-d', 'root']` +const userData = ` +#cloud-config +runcmd: + - ['sh', '-c', 'curl -fsSL https://tailscale.com/install.sh | sh'] + - ['tailscale', 'up', '--authkey=${process.env.TAILSCALE_AUTH_KEY}'] + - ['tailscale', 'set', '--ssh'] + - ['tailscale', 'set', '--accept-routes'] + - ['passwd', '-d', 'root'] +` Apply this suggestion Suggestion importance[1-10]: 8 Why: Using template literals for the userData string improves readability and maintainability, making it easier to manage and modify the multiline string.	8
Enhancement	✅ Use object destructuring to import multiple items from a package Suggestion Impact: The suggestion to use object destructuring to import both App and LogLevel was implemented. Additionally, LogLevel was used in the app initialization, which aligns with the suggestion's intention for future logging configurations. code diff: -const { App } = pkg; +const { App, LogLevel } = pkg; import CH from 'command-handler'; import path from 'path'; import 'dotenv/config'; @@ -22,6 +22,7 @@ signingSecret: process.env.SIGNING_SECRET, socketMode: true, appToken: process.env.APP_TOKEN, + LogLevel: LogLevel.DEBUG, Consider using object destructuring to import both App and LogLevel from the pkg object. This would allow you to keep the LogLevel import, which might be useful for future logging configurations. bot/src/index.js [1-2] import pkg from '@slack/bolt' -const { App } = pkg; +const { App, LogLevel } = pkg; Apply this suggestion Suggestion importance[1-10]: 7 Why: The suggestion to use object destructuring to import both App and LogLevel is valid and can improve future maintainability if LogLevel is needed again. However, since LogLevel is not currently used, the immediate impact is minimal.	7
