Hi @odd tartan. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Yes, it is possible to disable console logging in production for Convex using an environment variable. Here's how you can achieve this:
- Set an environment variable for your production deployment:
You can use the Convex CLI to set an environment variable for your production deployment. For example:
npx convex env --prod set DISABLE_CONSOLE_LOGS true
- In your Convex functions, check for this environment variable before logging:
if (process.env.DISABLE_CONSOLE_LOGS !== 'true') {
console.log("This will only log in non-production environments");
}
This approach allows you to keep your console.log statements in your code but have them only execute in development environments.
Additionally, Convex provides a built-in way to redact logs in production to prevent leaking of sensitive information:
Production > Environment Variables mentions:
"The cloud-hosted product automatically redacts logs to prevent any leaking of PII. If you would like to also redact log information in your self-hosted deployment, set the REDACT_LOGS_TO_CLIENT environment variable to true."
While this doesn't completely disable logging, it does provide an additional layer of security for production environments.
Remember that disabling all console logs in production might make debugging more difficult, so consider carefully whether this is the best approach for your use case.

@hazy hedge i used a lot of console.log, possible to redefine the ones in the browser?
hazy hedgeBOT
Let me check the knowledge base for you again. One moment! :books:
Yes, it's possible to redefine console.log in the browser when using Convex. This can be particularly useful if you want to control or modify the logging behavior in your client-side code. Here's how you can do it:
When initializing your Convex React client, you can use the logger option to provide a custom logger. This allows you to redefine not just console.log, but all logging methods.
Here's an example of how you can set this up:
const customLogger = {
log: (...args) => {
// Your custom logging logic here
// For example, you might want to disable logging in production:
if (process.env.NODE_ENV !== 'production') {
console.log(...args);
}
},
// You can define other methods like warn, error, etc. as needed
};
const client = new ConvexReactClient(process.env.NEXT_PUBLIC_CONVEX_URL!, {
logger: customLogger,
});
This approach is documented in the Convex API reference:
ConvexReactClientOptions Interface mentions the logger option:
"A logger. If not provided, logs to the console. You can construct your own logger to customize logging to log elsewhere or not log at all."
By providing a custom logger, you can control how logging behaves in your application. This allows you to:
- Disable logging in production
- Format logs differently
- Send logs to a different destination
- Add additional context to logs
Remember that this approach will only affect logs that go through the Convex client. If you have console.log calls elsewhere in your application, you might need to globally redefine console.log or use a similar approach in those areas as well.

@hazy hedge gimme example of how to use ite

Let me check the knowledge base for you again. One moment! :books:
Certainly! I'll provide you with an example of how to use a custom logger with the Convex React client. This example will show you how to redefine console logging behavior in the browser.
Here's a step-by-step example:
- First, define your custom logger:
const customLogger = {
log: (...args) => {
// Only log in development
if (process.env.NODE_ENV !== 'production') {
console.log('Custom log:', ...args);
}
},
warn: (...args) => {
// Always log warnings, but with a custom prefix
console.warn('Custom warning:', ...args);
},
error: (...args) => {
// Always log errors, but with a custom prefix
console.error('Custom error:', ...args);
}
};
- Then, use this custom logger when initializing your Convex React client:
import { ConvexReactClient } from "convex/react";
const convex = new ConvexReactClient(process.env.NEXT_PUBLIC_CONVEX_URL!, {
logger: customLogger,
});
- Wrap your app with the ConvexProvider:
import { ConvexProvider } from "convex/react";
function App() {
return (
<ConvexProvider client={convex}>
{/* Your app components */}
</ConvexProvider>
);
}
Now, when you use Convex functions or queries in your React components, they will use your custom logger. For example:
import { useQuery } from "convex/react";
import { api } from "../convex/_generated/api";
function MyComponent() {
const result = useQuery(api.myQuery);
// This will use your custom logger
console.log("Query result:", result);
// ...rest of your component
}
In this setup:
- Logs will only appear in development, not in production.
- Warnings and errors will always be logged, but with custom prefixes.
- All logs going through the Convex client will use this custom behavior.
This example is based on the information from the ConvexReactClient Class documentation and the ConvexReactClientOptions Interface documentation.
Remember, this will only affect logs that go through the Convex client. If you want to modify all console.log calls in your application, you would need to globally redefine console.log.

@hazy hedge Type '{ log: (...args: any[]) => void; warn: (...args: any[]) => void; error: (...args: any[]) => void; }' is missing the following properties from type 'Logger': _onLogLineFuncs, _verbose, addLogLineListener, logVerbose
Let me check the knowledge base for you again. One moment! :books:
It seems you're encountering a TypeScript error when trying to use a custom logger with the Convex React client. The error suggests that the custom logger object you've defined doesn't match the expected Logger type. Let's address this issue.
The Logger interface in Convex expects more properties than just log, warn, and error. To resolve this, you need to implement a full Logger interface. Here's an updated example that should work:
import { Logger } from "convex/browser";
const customLogger: Logger = {
log: (...args: any[]) => {
if (process.env.NODE_ENV !== 'production') {
console.log('Custom log:', ...args);
}
},
warn: (...args: any[]) => {
console.warn('Custom warning:', ...args);
},
error: (...args: any[]) => {
console.error('Custom error:', ...args);
},
_onLogLineFuncs: [],
_verbose: false,
addLogLineListener: (func: (line: string) => void) => {
customLogger._onLogLineFuncs.push(func);
},
logVerbose: (...args: any[]) => {
if (customLogger._verbose) {
console.log('Verbose:', ...args);
}
}
};
const convex = new ConvexReactClient(process.env.NEXT_PUBLIC_CONVEX_URL!, {
logger: customLogger,
});
This implementation includes all the required properties of the Logger interface:
_onLogLineFuncs: An array to store log line listener functions._verbose: A boolean flag to control verbose logging.addLogLineListener: A method to add log line listeners.logVerbose: A method for verbose logging.
The Logger interface is part of the Convex browser module, as mentioned in the BaseConvexClientOptions Interface documentation:
"A logger. If not provided, logs to the console. You can construct your own logger to customize logging to log elsewhere or not log at all."
By implementing all these properties and methods, your custom logger should now satisfy the TypeScript requirements for the Convex React client's logger option.
Remember to import the Logger type from "convex/browser" to ensure you're using the correct interface definition.
This solution should resolve the TypeScript error you're encountering while still allowing you to customize the logging behavior as needed.

@hazy hedge do you have a working example of this logger
hazy hedgeBOT
Let me check the knowledge base for you again. One moment! :books:
I apologize, but I don't have a complete working example of a custom logger implementation in the provided knowledge sources. However, I can provide you with a more detailed explanation based on the information we have.
The most relevant information we have comes from the ConvexReactClientOptions Interface documentation and the BaseConvexClientOptions Interface documentation. These sources mention that you can provide a custom logger, but they don't provide a full working example.
To create a working example, you would need to implement all the methods and properties of the Logger interface as described in my previous answer. However, without access to the full Logger interface definition, I can't provide a guaranteed working example.
If you're still encountering issues with implementing the custom logger, I would recommend:
- Checking the latest Convex documentation for any updated examples or more detailed information about the
Loggerinterface. - Consulting the TypeScript definitions in your project's
node_modules/convexdirectory for the exactLoggerinterface definition. - Reaching out to Convex support or community forums for a verified working example.
