Typescript error on Build (error TS7010: 'each', which lacks return-type annotation, implicitly has an 'any' return type.)

[jvUP]

Hi, after version 0.20.1 I was getting a typescript error on build. My last trying was with the 0.20.4 of grapesjs

to reproduce, I run this command: yarn run tsc

the output is:

node_modules/grapesjs/index.d.ts:29:5 - error TS7010: 'each', which lacks return-type annotation, implicitly has an 'any' return type.

29     each(callback: (item: TModel) => void);
       ~~~~

When I follow the line of error, I see this:

My tsconfig.json is settings as below

{
  "compilerOptions": {
    "target": "ESNext",
    "useDefineForClassFields": true,
    "lib": ["DOM", "DOM.Iterable", "ESNext"],
    "allowJs": false,
    "skipLibCheck": false,
    "esModuleInterop": false,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "noImplicitReturns": true,
    "module": "ESNext",
    "moduleResolution": "Node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx",
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/*"]
    }
  },
  "include": ["src"],
  "references": [{ "path": "./tsconfig.node.json" }]
}

If I understand correctly, we need to explicit the return value as any, because now it is only an implicit any

I will appreciate If someone can fix it, or knows how to fix it, or help me to know how to fix this in a PR

A possible solution / workaround is setting skipLibCheck: true in the compilerOptions property.

This will by fixed in the next release #4903
