TSLint has detected an error stating that the line exceeds the maximum length of 120 characters

Question

TSLint has detected an error stating that the line exceeds the maximum length of 120 characters

Within my Angular2 application, I am importing a single component in the following manner:

import { PersonsSingleAccountComponent} from 
   '../persons-information/fragments/persons-single-account/persons-single-account-bookings/persons-single-account-bookings.component'

This is causing a lint error stating "Exceeds maximum line character". Attempting to enclose the statement in backticks (`) results in an error.

Is there a way to resolve this lint error?

angular typescript tslint

Answer №1

Changing this is out of your control and not tied to your code.

To handle this import, it's best to simply comment out the rule like so:

// Disable tslint rule for maximum line length
import { PersonsSingleAccountComponent} from '../persons-information/fragments/persons-single-account/persons-single-account-bookings/persons-single-account-bookings.component'

Here's an alternative solution to address this issue.

Starting from version 5.9.0, the TSLint max-line-length rule now includes support for ignore patterns.

tslint.json:


{
  "rules": {
    "max-line-length": [
      true,
      {
        "limit": 120,
        "ignore-pattern": "^import [^,]+ from |^export | implements"
      }
    ]
  } 
}

This configuration will exclude specific lines specified in the ignore pattern:


import { SomeLongInterfaceName } from '../../../nested/directory/structure/target';
class MyClass implements SomeLongInterfaceName, OnInit, OnDestroy, OnViewChange {}
export { MyClass, SomeLongInterfaceName };

Kudos to DanielKucal for this contribution.

For the original poster's query, using ^import [^,]+ from is sufficient to disregard lengthy imports.

In my opinion, this approach is more favorable as it minimizes interference with the overall project TSLint rules and avoids the need to disable rules individually in each file through comments.

If you're encountering this error, there is an alternative solution - adjusting tslint rules for the entire project.

In my scenario, I was working on a pre-existing project where many lines exceeded the set limit. Although the code appeared clearer as an array of objects, VS Code highlighted the file with red underlines, making it difficult to read.

To resolve this, I made the following adjustment: "max-line-length": [ false ].

Alternatively, you can specify a different length by using "max-line-length": [ true, 240 ], achieving the same outcome.

Below is a snippet from my current tslint.json configuration:

{
    "extends": "../tslint.json",
    "rules": {
        "directive-selector": [
            true,
            "attribute",
            "app",
            "camelCase"
        ],
        "component-selector": [
            true,
            "element",
            "app",
            "kebab-case"
        ],
        "max-line-length": [ false ],
    }
}

Answer №4

There are a few strategies to address tslint - max-line-length warnings. Below, you will find three methods.

You can specify a rule in the tslint.json file to ignore specific statements.

 "rules": {
   "max-line-length": [
     true, 
     {
       "limit": 120, 
       **"ignore-pattern": "^import [^,]+ from |^export | implements"**
     }
   ],
 } 
}

You can modify the default max-line-length character limit in the tslint.json file.

            true,
            {
                "limit": **300**,
                "ignore-pattern": "^import |^export | implements"
            }
        ],

Add a comment above the targeted code line in the specified file.

// tslint:disable-next-line:max-line-length

// Your code goes here.

The tslint.json file can be found at the root of the project directory.

To enhance the organization of the files, I would suggest renaming them and eliminating any redundant naming conventions.

If individuals are working within a complex folder structure and these files are being utilized in various modules, it may be beneficial to include a path in the tsconfig file:

{
    "compilerOptions": {
        "baseUrl": "./src",
        "paths": {
            "@persons/*": [
                "app/shared/foo/bar/persons/*"
            ]
        }
    }
}

The end outcome would look like this:

import { PersonsSingleAccountComponent} from 
   '@persons/information/fragments/account/bookings/single-account-bookings.component'
