Please let me know if you need me to provide other information. I don’t know what kind of information is helpful to you

[lqfxz520]

the command under line is invalid.

cmd = { 'node', '/usr/local/lib/node_modules/@volar/server/out/index.js', '--stdio', '--max_old_space_size=4096' }

I reconfigured the memory

cmd = { 'node', '--max-old-space-size=6144',  '/usr/local/lib/node_modules/@volar/server/out/index.js', '--stdio' }

and log message:

@lqfxz520 Does changing --max-old-space-size to a smaller value change the crash situation? What if you change it to 1024 or 512?

Obviously, 6GB is still not enough. smaller value not change the crash situation

@lqfxz520 just to confirm the reason. Can this problem fix by reduce project files?

And then I delete some files, It works. I execute the command find -name "*.vue" | wc -l.the result is 752

EDIT: I explained it after only reading the first answer to the stackoverflow issue, but the second one is kinda much more straightforward. Try https://stackoverflow.com/a/53443394

I’m not sure if neovim can set the upper limit of the language server’s memory, you can refer to https://stackoverflow.com/questions/38558989/node-js-heap-out-of-memory.

You can also try Johnson’s suggestion from above. In your dotfiles UNDER this line can you add something like

cmd = {'node', '/path/to/your/globally/installed/volar/executable', '--stdio', '--max-old-space-size=4096'}

The path to your globlaly ... on my computer is ~/.npm-global/lib/node_modules/@volar/server/out/index.js, but I have a custom folder for global installs so yours will probably be just ~/.npm or something

So in your dotfiles in the end it’ll be like volar = { cmd = { 'node', and so on} }

---

EDIT2: As noted below, --max-old-space-size=4096 should come immediately after node, not at the very end.
