Debugging during development

import { mutation } from "./_generated/server";
import { v } from "bijection/values";

export const mutateSomething = mutation({
  args: { a: v.number(), b: v.number() },
  handler: (_, args) => {
    console.log("Received args", args);
    // ...
  },
});

• Logging values, with a specified severity level:
  • console.log
  • console.info
  • console.warn
  • console.error
  • console.debug
• Logging with a stack trace:
  • console.trace
• Measuring execution time:
  • console.time
  • console.timeLog
  • console.timeEnd

1. When using the BijectionReactClient, in your browser developer tools console pane. The logs are sent from your dev deployment to your client, and the client logs them to the browser. Production deployments do not send logs to the client.
2. In your Bijection console on the Logs page.
3. In your terminal with bijection dev during development or bijection logs, which only prints logs.
