Currently, I have eslint configured like this:
{
"extends": "google",
"installedESLint": true
}
When running lint on the following function:
app.get('/', (req, res) => {
console.log(req);
res.send('hello world')
});
I receive the following error:
ESlint: Parsing error: Assigning to rvalue
However, my code functions correctly without any issues.
Could anyone clarify what this error signifies and if there is an issue in my code?
To avoid errors related to arrow function syntax in your code, consider including the following configuration in your eslint setup:
{
"parserOptions": {
"ecmaVersion": 6
}
}
It's possible that there is a bug in the babel parser. As a temporary solution, you can try changing the arrow function to a traditional anonymous function like the example below:
app.get('/', function (req, res) {
console.log(req);
res.send('hello world')
});
I encountered a perplexing issue (Assigning to rvalue) while working with the code snippet below:
app.use(async (ctx, next) = > {
await next();
});
Reviewing my configuration file, I experimented with setting ecmaVersion to 6, 7, and 8. Previously, I discovered that I had to specify it as 8 for the async functions to be recognized. This particular structure is commonly used when developing a web server using koajs.
{
"parserOptions": {
"ecmaVersion": 7,
"sourceType": "module"
},
"rules": {
"semi": 2
}
}
