Hiding files and folders
The files.exclude setting lets you define patterns to hide files and folders from several places in VS Code like the explorer and search. Once defined, files and folders matching any of the patterns will be hidden.
{
"files.exclude": {
"**/*.js": true
}
}
Hide derived resources
If you use a language that compiles to another file at the same location of the source file, like TypeScript does to JavaScript, you can easily set an expression to hide those derived files:
"**/*.js": { "when": "$(basename).ts"}
Such a pattern will match on any JavaScript file (**/*.js), but only if a sibling file with the same name and extension, *.ts in this example, is present. The same technique can be used for other transpiled languages, like Coffee Script or Less/Sass, too.
