Could not find a declaration file for module sortablejs and dompurify

[Raw-Gel]

Hi I'm new in using the slick grid and I follow the HOWTO Step by Step procedure but when I start the project it return an error like this

which version is that with? Can you try to clone the Angular-Slickgrid-Demos instead, it works correctly, also maybe check that you're using "allowSyntheticDefaultImports": true, in your tsconfig.json file...or actually you might be missing the typesRoot in your tsconfig, both DOMPurify and SortableJS have their types defined in node_modules/@types so your tsconfig should have this setting to get them

https://github.com/ghiscoding/Angular-Slickgrid/blob/994cfe715efcda49a1d812ac7dbe61db3f1a62da/tsconfig.json#L19C4-L22

// tsconfig.json and/or tsconfig.app.json
"typeRoots": [
      "node_modules/@types"
],

I thought about it a bit more and it might be because these Types are not required (devDependencies in Slickgrid-Universal) and for that reason it might be why you're not resolving the types. I would guess that the 2 following would probably work

1. add SortableJS and DOMPurify types to your devDependencies

npm install -D @types/sortablejs
npm install -D @types/dompurify

2. modify your tsconfig.json to ignore types from external libs

// tsconfig.json or tsconfig.app.json
{
  "compilerOptions": {
    "skipLibCheck": true
  }
}

EDIT

I added @types/sortablejs as a dependency into Slickgrid-Universal so this error will never show up anymore. On the other hand, the @types/dompurify was not added to the dependency list because DOMPurify was made optional in latest major version, so if you install DOMPurify (recommended) then you will want to install its Type at the same time.

So I consider this problem resolved with info provided above
