Have Format On Save recognize `.prettierignore` within workspace/project subfolders

[cwhitemaddox]

Right now, with the prettier-vscode extension installed, the extension will recognize a .prettierignore file that is on the root of the vscode workspace/project, but it will not recognize any .prettierignore files that are within folders in that vscode workspace.

It would be helpful to have the prettier-vscode extension recognize and honor the .prettierignore files that are within folders in a vscode workspace. This is especially helpful in a monorepo context, where different folders of the monorepo can have different package.jsons and different .prettierignore files.

If, for example, you have a folder structure in a workspace like so:

codebase-1/
  package.json
  .prettierignore
  src/
    first-script.ts
    first-file-to-ignore.ts
codebase-2/
  package.json
  .prettierignore
  src/
    second-script.ts
    second-file-to-ignore.ts

And the contents of codebase-1/.prettierignore are:

src/first-file-to-ignore.ts

With the vscode workspace opened on code structure above, opening codebase-1/src/first-file-to-ignore.ts and saving the file (with Format On Save enabled), prettier-vscode will format the file and disregard codebase-1/.prettierignore.

• 2025-02-21: I confirmed on my setup re: the comment below that this issue appears to only affect .prettierignore files and not .prettierrc files in subfolders. Updated the copy above to reflect that.

To add to the issue, this also affects .prettierignore files. The current workaround is to duplicate the ignore file contents from subfolders into the repo root.

I can also verify this behaviour with .prettierignore files in my setup as reported in this StackOverflow post. Reading the documentation I expected to be able to create a .prettierignore file in my project but it was being ignored and like the other reports it has to be in the workspace root which in a multiroot workspace is the parent of all projects.

After some further tests it seems .prettierrc.json is recognised in any directory and does not have to be in the root directory of the project, however .prettierignore still has to be in the root directory to work at all. The workaround I've found is to create a prettierrc.json in any folder I want to ignore with a single { "requirePragma": true } rule inside.

Bump, although this issue should be renamed to be ignore file specific

I just updated this issue's title and the copy of my original post to reflect the scope only being .prettierignore files. I found the same with my setup
