How to install @types for all node modules automatically

I am new to Typescript and NodeJs. Whenever I mention a node module in package.json and while importing the the node module, I always get the following errors.

Could not find a declaration file for module 'ini'. 'e:/typescript-2020-1/parser1/node_modules/ini/ini.js' implicitly has an 'any' type.
  Try `npm install @types/ini` if it exists or add a new declaration (.d.ts) file containing `declare module 'ini';`

  Could not find a declaration file for module 'json-query'. 'e:/typescript-2020-1/parser1/node_modules/json-query/index.js' implicitly has an 'any' type.
  Try `npm install @types/json-query` if it exists or add a new declaration (.d.ts) file containing `declare module 'json-query';`

To solve this problem, I always search and install the followings in package.json as given below.

"dependencies": {
        "ini": "^1.3.5",
        "@types/ini": "^1.3.30",
        "json-query": "^2.2.2",
        "@types/json-query": "^2.2.0"
        "@types/node": "^13.9.0"
    }

How to avoid inclusion of all types of node modules specific types. Is it possible to do in a way that @types/<node module> will be added automatically inside node_modues without directly adding to package.json? I tried to add the following in tsconfig.json also, but it is not working.

"typeRoots": [
            "node_modules/@types"
        ],

Again my question is "Is it always necessary to add @types for each and every node modules ? Please help me to solve it.

If an npm package contains types, you will get them for free when you install.

If not, then you may be able to find them under the @types namespace on npm.

There is a useful tool called typac that you can install or run via npx that will try to install the @types for your package when you use it to install any npm package.

i.e.

    npx typac ini -i
