tslint says calls to console.log are not allowed - How do I allow this?

Add // tslint:disable-next-line:no-console in the line right before your calls to console.log to prevent the error message only once.

If you want to disable the rule entirely add the following to your tslint.json (most likely in your root folder):

{
    "rules": {
        "no-console": false
    }
}

For those of you coming here with a mixed codebase of javascript and typescript.

You may need to define the 'no-console' option in jsRules, jslints rules object for javascript files, i.e. there are separate rules objects for javascript and typescript.

//tslint.json

{
  "extends": ["tslint:recommended", "tslint-react", "tslint-config-prettier"], //Example... 
  "rules": {
    "no-console": false //Disable for typescript
  },
  "jsRules": {
    "no-console": false //Disable for javascript
  }
}

Add the following to your tslint.json

{
   "rules": {
      "no-console": {
         "severity": "warning",
      } 
   }
}

This is the correct syntax to define the no-console rule (or any other rule for that matter) but only with a warning rather than an error (obviously change the options to whatever you want)

"no-console": {
    "severity": "warning",
    "options": [
        "log",
        "error",
        "debug",
        "info",
        "time",
        "timeEnd",
        "trace"
    ]
},

The way I handle tslint "no-console" rule is per file which I have found is convenient and isolated in the development phase.

As soon as I need to use the first console.log(); Visual Studio Code shows the option to add:

// tslint:disable-next-line: no-console console.log();

So here I just delete "-next-line" and this command will cover the entire file.

// tslint:disable: no-console console.log();

I hope it helps as an alternative to disable the feature for the entire app.

if // tslint:disable-next-line:no-console doesn't work try with // eslint:disable-next-line:no-console

in typeScript version 3 update tslint.json under key rule like below:

"no-console": [
    true,
    "debug",
    "time",
    "timeEnd",
    "trace"
],

this way you just specify debug, time, timeEnd, trace to be not used, if in your default tslint "info" is in the list just remove it.

Just a dirty hack to bypass linter:

const { log } = console; log('Hello linter'); // TODO: remove

According to the docs: https://eslint.org/docs/user-guide/getting-started#configuration

"off" or 0 - turn the rule off

"warn" or 1 - turn the rule on as a warning (doesn’t affect exit code)

"error" or 2 - turn the rule on as an error (exit code will be 1)

By the way, your correct setup would be

{
  "rules": {
    "no-console": false
  }
}

  {
    "extends": ["tslint:recommended", "tslint-react", "tslint-config-prettier"],
    "linterOptions": {
        "exclude": [
            "config/**/*.js",
            "node_modules/**/*.ts",
            "coverage/lcov-report/*.js"
        ]
    },
    "rules": {
        "no-console": false
    },
    "jsRules": {
        "no-console": false
    }
 }

The Syntax changed!

For the next-line exception there needs to be a space before no-console: // eslint-disable-next-line no-console.

For the file exception, it also has to be inside of the Multi-line comment syntax: /* eslint-disable no-console */.

It also might depend on certain configurations.

For those coming here looking for a way to keep console.log as disallowed, but to allow helpful methods like console.time and console.timeEnd, for example, you can explicitly define it globally in your .eslintrc rules:

 "no-console": ["error", {"allow": ["time", "timeEnd", "trace"]}],
