Atom Crashes When Trying to Save HTML Files

[ghost]

I'm using Atom 1.34.0 on Windows 10 and I had configured Prettier to format on-save. It works fine on javascript files but when I try to save HTML files, it hangs and I have to force close the app.

I know that Prettier is the problem because once I disabled it, the HTML file saved no problem.

How can I go about fixing this? The package version of prettier-atom is 0.56.2

How big is the HTML file you’re saving?

Also, can you confirm that this works fine outside of prettier-atom (using Pretter directly)?

It's only 34kb

I ran Prettier from the CLI and it worked perfectly.

Same for me with a 28kB html. Prettier CLI works fine. I have disabled autoformat for *.html until this is fixed.

Can someone give me some sample html and filename that fails for them and I can try to reproduce locally?

I started out by modifying this template:

evelyn.zip
test with the index.html

I have redone most of it on my own but I have never been able to format it with prettier in Atom.
(prettier CLI works fine)

I am experiencing this issue still with the following html file: index.html gist

Can confirm. Tried saving a file with 200 lines of SVG inline and it consistently crashed my editor.

Me too

@uyouthe Can you provide a gist if possible? I'm not sure what the common thread here is, but it seems to be based on the actual code in the file and very rare. I want to see if there's something obvious about what's going on.

Awesome, I think I've narrowed down the issue. When calling prettier.formatWithCursor, prettier has an out of memory error.

It is this old issue here: prettier/prettier#4801

While we wait for Prettier to fix it, what I suggest you do is run prettier from the command line to format the file the first time. This uses the normal (as opposed to formatWithCursor) method so it shouldn't crash. From then on, the diff should be much more manageable for Prettier and you shouldn't have the issue again and you can just use prettier-atom as normal.
