I've started learning React Native.
I'm using Visual Studio Code as my editor.
I've set up the boiler plate and started the app. But whenever I change a .js file and hit save, VSCode is messing up all the formatting.
I thought I could sort this in the settings.json file but after googling for a while and playing around I can't find the correct setting.
Is this a bug or am I doing something wrong?
Setting file is default one:
UPDATE: I re-installed vscode. Then set up a basic js file with a react native tag and a html tag. I added in:
"editor.formatOnSave": false,
"javascript.format.enable": false
To my settings.json file and the problem still occurs:
The problem is having tags in a js file, I just don't know how to tell vscode to ignore them?
I found out what this was by looking though the extensions. Thanks to #wgj for the hint.
Turns out it was the JS-CSS-HTML formatter. I looked through the instructions and have removed the auto save for now. I'll have to work out the specific settings for this.
It uses js-beautify so if anyone knows the settings I should be looking at would be much appreciated.
I had a similar problem and it turned out my ultimate culprit was...
So I simply disabled it for the workspace.
Same here, all my HTML format messed up after saving, I disable "JS-CSS-HTML Formatter" and problem solved
In the end, what did the trick was changing the file format from JavaScript to JavaScript React on the bottom toolbar.
All my HTML format messed up in js after saving, I disable "JS-CSS-HTML Formatter" and restarted vscode, problem solved.
I found my solution to this problem by converting my components file extension from js to jsx. No more issues and everything is working fine.
Disable js-css-html formatter.
if you are using prettier and beautify together, override the setting as :
"beautify.ignore": [
"**/*.js",
"**/*.jsx"
]
Use Prettier Code Formatter instead of Beautify. Works perfectly for language mode Babel JavaScript
You should search for "format" in settings.json. You'll find a whole lot of TypeScript/JavaScript formatting tweaks in there, but the one that stands out to me is:
// Defines space handling after opening and before closing non empty brackets.
"javascript.format.insertSpaceAfterOpeningAndBeforeClosingNonemptyBrackets": false
Alternative, you're not a fan of formatting at all, you can turn it off entirely:
// Enable/disable default JavaScript formatter.
"javascript.format.enable": true,
However, a lot of my formatting options come from language server extensions, so if you're using one for React Native specifically, be sure to check the attributes in settings.json, or the docs to see if there are any attributes you can add.
Add this on settings.json file. Whether you are using any extension or not, use this code. It works fine for me:
Solution 1: Just Disable JS-CSS-HTML Formatter
Solution 2: Press Ctrl+, (open settings) after that search Code formatted and change none --> Prettier
If you don't have prettier install from the extension's marketplace.
i just had this problem , apparently its because of the beautify/prettier , try to disable both , then restart Vs code (your editor) . but then if u really want to use prettier , go under its extension settings and make sure its in strict with whitespaces and toogle around a few other settings and you should be fine , cheers .
Just turning off format on save option from the settings would work.
You can select JavaScript React in the task bar under Select Language Mode.
You can try one of the following
uninstall other formatters which are not required. To check how many formatters you have just press ctrl + shift + p or command +shift + p (mac) and type format document after that a menu will appear showing you your formatters
press ctrl + shift + p or command +shift + p (mac) and type settings and click on open users settings and then search for format on save and check the box
that's it!!
Enjoy
changing the file format from JavaScript to JavaScript React on the bottom toolbar worked just fine for me
I have tried all methods but the problem is solved completely by this:
-> Open setting.json
-> "files.associations": {
"*.js": "javascriptreact"
}
->Add above lines and press save the problem will solve
You can type the following command string when creating your project
npx create-react-app name-of-app react-complete-guide
or the following, if you have create-react-app installed already
create-react-app name-of-app react-complete-guide

I have read about 10-15 other answers now and none of the solutions (which are all the same minus 3 or 4) have worked for me. I am using Prettier and Vetur and I have the ESLint extension in VSCode installed as well. I have looked over the settings at least 10 times in the past 3 days trying to touch everything, close/open VSC and save to format, check if the problem persists, and continue doing this with each setting one-by-one trying to eliminate the suspects. I am here as a last resort out of desperation to be able to save my components without breaking my html tags and separating code into illegible BS.
My expected code formatting looks like this:
<button
class="btn btn-success"
#click="sellStock"
:disabled="insufficientFunds || quantity <= 0 || !Number.isInteger(quantity)"
>{{ insufficientQuantity ? "Not enough Stocks" : "Sell" }}</button>
and my formatter is causing the " at the end of the line after "...isInteger(quantity)" to be line-broken which breaks my entire component's syntax/major linter errors appear (obviously).
<button
class="btn btn-success"
#click="sellStock"
:disabled="
insufficientFunds || quantity <= 0 || !Number.isInteger(quantity)
"
>
{{ insufficientQuantity ? "Not enough Stocks" : "Sell" }}
</button>
As you can see, even the line breaks are uneven and make ZERO sense formatter-wise...I've never seen it do this before. This is next-level annoying Vue/Vetur/Prettier/VScode formatting bugs now and I'm quite stumped as to why it's suddenly acting up this week.
I have tried changing word-wrap-length and prettier lengths and indentations, font size and appearance of the mini map...nothing seems to make this madness stop, not even turning of html formatting period. It also formats some of my other ".vue" components into multiple lines when I don't want it to, but it isn't breaking the syntax/html tags as it is here. I have made the word-wrap/line-length 200+ everywhere that it's listed as a settings and it continues to break my code.
Any ideas?
Only advice I can give is stop using Prettier. Trying to make it work with ESlint and Vetur was always pain. Then I found this question (and self answer) here on SO which recommends dropping Prettier and using ESlint not just for linting but also for formatting (needs version >= 6). I'm happy as clam now...
I've been struggling with a similar problem with VSCode's formatting. I also have Prettier, ESLint and Vetur extensions installed. But my code formatting rules were somehow different from my co-worker's (they are using WebStorm by the way).
In my case, the problem was solved by:
Turning off all the Vetur formatters and disabling all formatting capabilities of Vetur.
Enabled ESLint as the formatter.
This seems to have allowed the Prettier extension to look at .eslintrc.js, which the Prettier plugin is setup.
I suggest that you look in on the Prettier extension logs to debug your problem.
On the bottom right corner of VSCode's window, you will see the Prettier extension indicator. Click on this and you can see the logs.
Once the logs are shown, you can see where the extension is getting the Prettier configs from, or where the Prettier module is being imported from.
What helped me with this situation, I went into Vetur's extension settings inside VSCode Vetur > Format > Default Formatter: HTML and selected js-beautify-html.
I just had this problem and resolved it.
The issue I had was that my html in the .vue file was malformed (Specifically I had a closing tag which shouldn't have been there).
I was relying on it formatting on save, and when that didn't work I tried manually selecting "format document with prettier" which did nothing.
It was only when I looked in the output window (Which I should have done immediately) that I saw that it was complaining about the misplaced closing div tag.
It's a silly oversight, but easily made.
What fixed it for me was to actually turn on Eslint to work as a formatter in settings.
Due to logs, I just needed to install the prettier dependency, so:
yarn install
or, if you do not have it already, add it:
yarn add prettier
this fixed my problem.
I'm using Visual Studio Code to code a Vue.js component and need to reformat the code of that component.
I did not find any built-in formatters, and the first choice for a plugin was vue-buetify which informs after installation that
There are many bugs in the extension, please do not use it, the better choice is vetur
I then tried Vetur by installing it but there is no place where I see an option to beautify the code currently in the editor. The Shift + Alt + F command has no effect.
How can I actually beautify (reformat) the code for a Vue component?
I've been fiddling with formatting quite a bit since my previously working project stopped formatting one day. Here's what I think the current state of the art is:
Use extensions vetur and prettier (specifically, esbenp.prettier-vscode Prettier - Code formatter). (You get these preinstalled by Vue.js Extension Pack esbenp.prettier-vscodeand others.)
Vetur is the (current) mandatory default tooling for vue. Accept no substitutes.
Prettier doesn't support .vue files per se, so that filetype is disabled by default: https://github.com/prettier/prettier-vscode/issues/338.
But Vetur understand its limitations and instead delegates formatting of individual sections of the .vue file to a potentially different formatter. By default, though, it delegates everything other than HTML sections to Prettier. https://vuejs.github.io/vetur/formatting.html. It disables formatting for HTML sections.
Vetur developers are down on js-beautify-html, although it is still apparently functional: https://vuejs.github.io/vetur/formatting.html. And they don't make an alternative recommendation at this time.
Prettier support for HTML, which would be the obvious choice if only it existed, is a long, sad story. Currently (May 2018), prettier formats HTML as JSX. Many subtleties are mentioned, but one issue that I have grasped is that JSX converts begin/empty/end tags to empty tags, e.g to . Apparently React and (I believe) Vue, do not like this, hence vetur disables Prettier for HTML.
So I'm going forward with enabling js-beautify-html in vetur settings, hoping for the best and keeping my eyes peeled. But I'm such a superficial coder that I may never trip over its known issues.
In 2022, the situation regarding formatting Vue files regaled in another answer has vastly improved.
Vetur is still the de facto solution for managing .vue files in VS Code, but in the time since this question was asked, Prettier added full support for them (and HTML proper). This means you can format them using Prettier without Vetur if you so desire.
Note that Vetur does not support VS Code's "Format Selection" functionality, even though Prettier does (for a small set of languages):
Vetur only has a "whole document formatter" and cannot format arbitrary ranges. As a result, only the Format Document command is available.
The Format Selection command does not work.
If you do decide to use Vetur, you shouldn't need any other extensions to get formatting to work, as the extension comes bundled with all of its available formatters. As long as you have the extension installed and enabled, formatting with the "Format Document" command or Shift + Alt + F should work out of the box.
Vetur's settings allow the user to configure which of its available formatters is used for each language it supports (Prettier is the default for all but Sass and Stylus). The formatters can also be toggled off per language, or entirely, if you prefer to use some other formatting solution instead.
If you have installed the Vetur extension on VS Code,
Go to the VS Code extension area.
Find Vetur and select the gear icon to enter settings of Vetur.
Scroll down until you find
Vetur › Format › Default Formatter: JS
Default formatter for <script> region
Select pretter-eslint from dropdown menu
(if you don't see that option you can install Prettier extension).
Now you can see it formats your code automatically whenever you save.
While debugging my React Native app in Chrome, I'm often unable to set breakpoints in the Sources tab. When I click on a line of code to add the breakpoint, a breakpoint is added instead to the next function declaration line in my module.
This doesn't happen in all of my source modules, but often enough that it prevents me from debugging efficiently.
I'm currently using RN 0.22 but this has been happening on older versions of RN as well (e.g. RN 0.18).
This problem maybe caused by babel. When use normal function and arrow function together, it happened.
"sourceMaps": "inline" in .babelrc fixed this for me.
I've only experienced this issue under the following conditions:
1) The .js file contains multiple functions, and
2) Attempting to set a breakpoint within a function that is not the last function in the .js file
So, a partial workaround is to move a function such that it is the last function in the .js file. Or, you could assign a single function per file. Either way, you will be able to set breakpoints.
This is far from ideal, but it's the only "solution" I've found so far.
I had the same issue, and I have a cozy solution for now :
I put the word "debugger" in the file which I want to debug.
I refresh the browser to see that it stops.
after it stops, I can add as much as breakpoints as I want and remove the "debugger" word from file
Try this package
https://www.npmjs.com/package/react-breakpoint-fix
just install the package and run react-breakpoint-fix from the terminal.
This fixed it for me. I'm using react-scripts#3.x
Brand new to Atom. I see that I can force some html tags to close inline using the autoclose-html package. However, when I populate the list with tags to close inline, they are still closing on a separate line. How should the list be formatted? I see the defaults as
default: ['title', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6']
And so I first tried adding ...'p', 'span'] to the list, and it did not work. I then found a list in autoclose-html.coffee and added the same, to no avail. What am I doing wrong?
The way I did this (Mac OS - should be same for other OS's):
Bring up Atom Settings (Atom menu --> Preferences)
Select Packages
Select autoclose-html Settings
Select View Code
Expand the lib folder
Select configuration.coffee
Make your changes in there and save the file.
Restart Atom
All done!
I don't know whether you have fix this issue. I just work it out.
It's nothing about this package, it's handled by atom's html-language plugin. Just open Atom->Snippets and add the following codes:
Sorry the preview looks terrible when I post the code as text. So I post a image here.
Is it possible to wrap long comment lines in IntelliJ in javascript files? I have turned on line wrapping as shown in the settings below, but when I do a code reformat, it doesn't wrap the line.
It's not supported yet on code reformatting, added a new feature request, please vote.
I'm using IntelliJ 14 on a Mac, which has a Fill Paragraph command. Access it via the awesome universal Command-Shift-A action search feature. Works like a charm!
