Block must not be padded by blank lines.
Open

Severity: Minor
Found in setup/postinstall.js by eslint

require or disallow padding within blocks (padded-blocks)

Some style guides require block statements to start and end with blank lines. The goal is to improve readability by visually separating the block content and the surrounding code.

if (a) {

    b();

}

Since it's good to have a consistent code style, you should either always write padded blocks or never do it.

Rule Details

This rule enforces consistent empty line padding within blocks.

Options

This rule has one option, which can be a string option or an object option.

String option:

  • "always" (default) requires empty lines at the beginning and ending of block statements (except switch statements and classes)
  • "never" disallows empty lines at the beginning and ending of block statements (except switch statements and classes)

Object option:

  • "blocks" require or disallow padding within block statements
  • "classes" require or disallow padding within classes
  • "switches" require or disallow padding within switch statements

always

Examples of incorrect code for this rule with the default "always" option:

/*eslint padded-blocks: ["error", "always"]*/

{
    b();

}

    b();

}

    // comment

disallow the use of console (no-console)

In JavaScript that is designed to be executed in the browser, it's considered a best practice to avoid using methods on console. Such messages are considered to be for debugging purposes and therefore not suitable to ship to the client. In general, calls using console should be stripped before being pushed to production.

console.log("Made it here.");
console.error("That shouldn't have happened.");

Rule Details

This rule disallows calls to methods of the console object.

Examples of incorrect code for this rule:

/*eslint no-console: "error"*/

console.log("Log a debug level message.");
console.warn("Log a warn level message.");
console.error("Log an error level message.");

Examples of correct code for this rule:

/*eslint no-console: "error"*/

// custom console
Console.log("Hello world!");

Options

This rule has an object option for exceptions:

  • "allow" has an array of strings which are allowed methods of the console object

Examples of additional correct code for this rule with a sample { "allow": ["warn", "error"] } option:

/*eslint no-console: ["error", { allow: ["warn", "error"] }] */

console.warn("Log a warn level message.");
console.error("Log an error level message.");

When Not To Use It

If you're using Node.js, however, console is used to output information to the user and so is not strictly used for debugging purposes. If you are developing for Node.js then you most likely do not want this rule enabled.
