In its current form, JavaScript is an interpreted programming language based on the prototype concept. This language is commonly used for web pages and server-side applications.
You will receive the following message when you complete your task: “error axios is defined but never used no-unused-vars“.
This became one of the most common errors that any programmer could make. As a result, why does it happen, and is it solvable? Let’s work together to identify the most effective approaches.
What is “error ‘axios’ is defined but never used no-unused-vars” Happen?
You are getting the error ‘axios’ is defined but never used no-unused-vars, which you are attempting to disable. You tried adding the / eslint-disable-next-line no-unused-vars comment, which you read would help, but you still get this error!
Here is code:
<template>
<div class="text-breakdown">
<h3 class = "title">Text Breakdown</h3>
<form onsubmit="greet()">
<textarea type="text" id = "breakdown-text"
placeholder="Enter your text here">
</textarea>
<button class = "custom-button dark-button"
type="submit">Breakdown</button>
</form>
</div>
</template>
<script>
// eslint-disable-next-line no-unused-vars
import axios from 'axios';
// eslint-disable-next-line no-unused-vars
function greet() {
alert("Hello!");
}
</script>
How to deal with it?
Amazingly, you fixed it by employing some of the methods listed below.
Solution 1: Set “no-unused-vars”: “off”
Add this to your package.json file and restart your dev server. The rules key should not appear twice in your package.json file.
"rules": {
"no-unused-vars": "off"
}
If you’re using Typerscript, try this code:
rules: {
"no-unused-vars": "off",
"@typescript-eslint/no-unused-vars": "off",
}
Solution 2: Disabling a rule on a single line
This second approach is one of the simplest we’ve ever encountered.
Simply add / eslint-disable-next-line no-unused-vars above the line you want to disable to disable an eslint rule on one line, for example:
// eslint-disable-next-line no-unused-vars
import axios from 'axios';
You put your comment in the wrong place; it should be above import axios from ‘axios’; so move it.
// eslint-disable-next-line no-unused-vars
import axios from 'axios';
To
// eslint-disable-next-line no-unused-vars
import axios from 'axios';
Solution 3: Use this code
Locate the eslintConfig, including the rules object with the following properties in the package.json file.
"eslintConfig": { "rules": { "no-unused-vars": "off", "no-console": [ "warn",{ "allow":[ "clear", "info", "error", "dir", "trace", "log"]} ], } },
Approach 4: Ignore variables prefixed with “-“
In this solution, you will fix the error by Ignore variables prefixed with “-“, Use this code:
rules: {
'no-console': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
'no-debugger': process.env.NODE_ENV === 'production' ? 'warn' : 'off',
'no-unused-vars': ['warn', {
argsIgnorePattern: '^_',
varsIgnorePattern: '^_'
}]
}
Conclusion
JavaScript is one of the three main languages of web programming, and it has been widely used for the past years.
If you’re still perplexed by the message “error ‘axios’ is defined but never used no-unused-vars“, the solutions provided below are the most effective.
Even if you still require assistance or have fundamental Javascript concerns, there is a large community to which you can turn, and everyone is often eager to assist. Finally, we’d like to wish all our readers a wonderful day full of new ideas.
