How to disable JavaScript build error in Visual Studio 2017?

I just updated Visual Studio 2017 from RC to final. I didn’t get the following error but recently I get this error. In building the project, I get the following error and it prevents the web project to start:

Severity    Code    Description Project File    Line    Suppression State
Error   eqeqeq  (ESLint) Expected '===' and instead saw '=='.   VistaBest.Shop.Web  C:\***\Request.js   21

JavaScript Error

How can I disable JavaScript building error in Visual Studio 2017?

Answers:

Answer

I think, find the solution:

  1. Open Tools > Options
  2. Navigate to Text Editor > JavaScript/TypeScript > EsLint (in VS2017 15.8 it is Linting not EsLint)
  3. Set Enable ESLint to False

Disable ESlint

Visual Studio >= 15.8.5 Disable ESlint Visual Studio 15.8.5

Answer

In Visual Studio 2017 (v 15.8.0):

Option 1: Options > JS Errors

  1. Open Tools > Options
  2. Navigate to Text Editor > JavaScript/TypeScript > Code Validation
  3. Set Enable JavaScript errors to false
  4. or, set Enable JavaScript errors to true and Show errors as warnings to true

I needed to restart Visual Studio for this to take effect.

Options > JS Errors

Option 2: Options > Linting

There is another option below which will let you edit your global linting settings:

Options > JS Linting

Option 3: .eslint file

You can also create a file named .eslintrc in the root of your project.

Option 4: ESLint commands in-file

Answer

I tried Mohammad`s solution but it didn't work. I managed to work doing the following:

  1. Righ click on your web .csproj file
  2. On the first <PropertyGroup> add the following entry: <TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>
Answer

Add /*eslint eqeqeq: ["error", "smart"]*/ to the first line of your Javascript code to remove the errors. https://eslint.org/docs/rules/eqeqeq

Following Mohammad's solution will turn off ESLint for syntax checking. This works in VS2015 and should work in later versions.

Answer

For Visual Studio 2019.

enter image description here

  1. Open Tools > Options
  2. Navigate to Text Editor > JavaScript/TypeScript
  3. => Linting > General.

Then unchecked ESLint check box. Please The bellow Image for reference.

Answer

I've just had to change the "eqeqeq" rule behaviour to include "smart":

Edit the .eslintrc file found in your user root folder mentioned in other answers already.

The change is made to the rules section by adding the smart rule

    "rules": {

    "eqeqeq": [2, "smart"],

Copied from the web article: This option enforces the use of === and !== except for these cases:

  1. Comparing two literal values
  2. Evaluating the value of typeof
  3. Comparing against null

I found the specifics at: https://eslint.org/docs/2.0.0/rules/eqeqeq

Answer

I tried Mohammad's solution but with no luck, I followed Rafeel answer and instead of adding his suggested code sample I removed below code from web .csproj and finally I was able to build and run my project. There were two places where you should remove that in the same file. Still, I don't have any clue how the removed code will affect my solution.

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.Default.props" Condition="Exists('$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.Default.props')" />

Hope this will also help someone to save the day..!!!
