feat(cmd): add status command with ckb-tui by RetricSu · Pull Request #323 · ckb-devrel/offckb

RetricSu · 2025-12-02T08:03:15Z

This PR adds a new cmd status. Once you start the CKB Node with offckb node on your local computer, you can use offckb status --network devnet/testnet/mainnet to start a CKB-TUI interface to monitor the CKB network from your node.

If the binary is not found after extraction (neither in the bin directory nor in subdirectories), the code silently continues without throwing an error or logging a warning. This could lead to confusing behavior later when trying to execute the binary. Consider adding an error check after the loop at line 84 to verify that the binary was successfully extracted and moved.

Suggested change

// Check that the binary was successfully extracted and moved

if (!fs.existsSync(this.binaryPath!)) {

logger.error(`ckb-tui binary was not found after extraction. Expected at: ${this.binaryPath}`);

throw new Error('Failed to extract and locate ckb-tui binary.');

}

+    client.once('error', () => {
+      resolve(false);
+    });
+    client.connect(port, '127.0.0.1');
+    client.once('connect', () => {
+      client.end();
+      resolve(true);
+    });


The socket connection is never cleaned up if neither the 'error' nor 'connect' event fires in a timely manner. This can lead to resource leaks. Consider adding a timeout to ensure the socket is closed and the promise resolves even if the connection hangs indefinitely.

Suggested change

client.once('error', () => {

resolve(false);

});

client.connect(port, '127.0.0.1');

client.once('connect', () => {

client.end();

resolve(true);

});

let settled = false;

const TIMEOUT_MS = 5000;

const timeout = setTimeout(() => {

if (!settled) {

settled = true;

client.destroy();

+  static runWithArgs(args: string[]) {
+    this.run(args);
+  }


The runWithArgs method is redundant and simply calls the run method. This doesn't add any value and can be removed. All callers should directly use the run method instead.

Suggested change

static runWithArgs(args: string[]) {

this.run(args);

}

+}
+
+async function isRPCPortListening(port: number): Promise<boolean> {
+  const net = require('net');


Using require inline within a function is not consistent with the ES6 import style used elsewhere in the file. Consider importing the net module at the top of the file with import * as net from 'net'; for consistency.

+    } catch (error) {
+      logger.error('Failed to download/install ckb-tui:', (error as Error).message);
+      throw error;


If an error occurs during extraction or binary setup (lines 59-85), the downloaded archive file won't be cleaned up. Consider wrapping the cleanup in a finally block or moving it earlier to ensure cleanup happens even when errors occur.

Suggested change

// Clean up archive

fs.unlinkSync(archivePath);

logger.info('ckb-tui installed successfully.');

} catch (error) {

logger.error('Failed to download/install ckb-tui:', (error as Error).message);

throw error;

+      } else {
+        throw new Error(`Unsupported architecture for macOS: ${arch}`);
+      }


macOS x64 architecture is not supported, but it's a valid and commonly used platform. Consider adding support for macOS x64 systems by including the appropriate asset name (similar to how Linux x64 is supported).

+      logger.info('ckb-tui installed successfully.');
+    } catch (error) {
+      logger.error('Failed to download/install ckb-tui:', (error as Error).message);


The error message logs (error as Error).message but doesn't provide context about what might have gone wrong. Consider including more specific guidance, such as checking network connectivity, verifying the version exists in the releases, or checking file system permissions.

Suggested change

logger.error('Failed to download/install ckb-tui:', (error as Error).message);

logger.error(

'Failed to download/install ckb-tui:',

(error as Error).message,

'\nPlease check your network connectivity, verify that the specified version exists in the releases, and ensure you have sufficient file system permissions.'

+  .description('Show ckb-tui status interface')
+  .option('--network <network>', 'Specify the network to deploy to', 'devnet')
+  .action(async (option) => {
+    status({ network: option.network });


The status function is called without await, but it's declared as async in the status.ts file. This means errors thrown in the function won't be caught by this action handler. Add await to properly handle the async operation.

Suggested change

status({ network: option.network });

return status({ network: option.network });

+  .command('status')
+  .description('Show ckb-tui status interface')
+  .option('--network <network>', 'Specify the network to deploy to', 'devnet')


The network option accepts any string value without validation. If a user provides an invalid network name (e.g., "production" or "dev"), it would be passed through without error checking. Consider validating that the network value is one of the valid Network enum values ('devnet', 'testnet', 'mainnet') and providing a helpful error message if it's not.

src/tools/ckb-tui.ts

+    const command = `"${binaryPath}" ${args.join(' ')}`;
+    return spawnSync(command, { stdio: 'inherit', shell: true });


The run method constructs a shell command by joining args without sanitization, which could allow command injection if any argument contains shell metacharacters (e.g., ;, |, &, etc.). Consider using spawnSync with the arguments array directly instead of constructing a shell command string: spawnSync(binaryPath, args, { stdio: 'inherit' }).

Suggested change

const command = `"${binaryPath}" ${args.join(' ')}`;

return spawnSync(command, { stdio: 'inherit', shell: true });

return spawnSync(binaryPath, args, { stdio: 'inherit' });
