I'm using prettier and eslint with typescript.
When I write some code and have to leave an empty function for reasons , Eslint and Prettier struggle adding and removing spaces between the empty function's braces.
Prettier is removing the space while Eslint is adding it.
What is expected:
constructor(
@inject('UsersRepository')
private usersRepository: IUsersRepository,
) {}
const example = ({ variable }) => {
console.log(variable)
};
What I get after saving (Eslint fixing on save):
constructor(
@inject('UsersRepository')
private usersRepository: IUsersRepository,
) { }
const example = ({ variable }) => {
console.log(variable)
};
Se the space between the constructor braces? That gives me a Delete `·` eslint(prettier/prettier)
error.
When I save the file, or Prettier removes the space... then Eslint adds it again.
How can I solve this?
EDIT: I want to keep the destructuring assignment space (eg ({ variable })
) but not on empty braces (eg {}
)
Below, my .eslintrc.json
and prettier.config.js
{
"env": {
"es6": true,
"node": true,
"jest": true

I've had very similar error, but in my case default VSCode TypeScript formatter was messing with braces. In.vscode/settings.json add:
"javascript.format.insertSpaceAfterOpeningAndBeforeClosingEmptyBraces": false,
"typescript.format.insertSpaceAfterOpeningAndBeforeClosingEmptyBraces": false,
You might also find useful option:
"[typescript]": {
"editor.defaultFormatter": "dbaeumer.vscode-eslint"
}
You should use this in the settings file of vscode.
"prettier.bracketSpacing": false
I had the exact same problem, where prettier stopped working all of a sudden. Auto-format on save(vs code settings) adds a space for braces and linters threw an error on the same. Spend a lot of time debugging this and did the below steps to fix my issue
1: Re-install vscode prettier extension.
Go to vscode => cmd + p and type ext install esbenp.prettier-vscode
.
2: My vscode settings.json and prettier.js looks somewhat like this
vscode settings.json
{
"editor.codeActionsOnSave": {
"source.organizeImports": true,
"source.fixAll.eslint": true,
"source.fixAll.tslint": true,
"source.fixAll.stylelint": true
},
"css.validate": false,
"files.autoSave": "off",
"typescript.updateImportsOnFileMove.enabled": "always",
"javascript.updateImportsOnFileMove.enabled": "always",
"editor.wordWrap": "on",
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": false,
"[typescriptreact]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true
},
"[javascript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true
},
"[typescript]": {
"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true
}
}
Prettier.js
module.exports = {
semi: true,
trailingComma: 'none',
singleQuote: true,
printWidth: 80,
tabWidth: 2,
endOfLine: 'auto',
bracketSpacing: true,
proseWrap: 'always'
};
I has a bad experience with prettier thanks to this post I managed to put together a nice settings config so Im sharing it here and hopefully it will;help someone top.

I haven't started coding in typescript yet but when I do lll male a new config:)
Happy coding
