Cannot build node API due to typescript issues

[prabir-vora]

My node API compilation fails while building using tsc. Getting 29 type errors in types.d.ts.

As mentioned in #834 and #841 I tried adding the "skipLibCheck": true and "lib": ["DOM"] flag to my tsconfig.json. I additionally event tried adding --skipLibCheck flag to my build command. However, the type files from stream-chat are not getting ignored.

Here is what my tsconfig.json looks like

{
    "compilerOptions": {
        "target": "es2018",
        "module": "commonjs",
        "lib": ["es2015", "es2018", "esnext.asynciterable", "DOM"],
        "skipLibCheck": true,
        "sourceMap": true,
        "outDir": "build",
        "rootDir": "./",
        "strictFunctionTypes": true,
        "noImplicitAny": true,
        "strictNullChecks": true,
        "noUnusedLocals": false,
        "noUnusedParameters": false,
        "noImplicitReturns": true,
        "noFallthroughCasesInSwitch": true,
        "baseUrl": "./src",
        "paths": {
            "*": ["typings/*"],
            "@app/*": ["app/*"],
            "@service/*": ["services/*"],
            "@model/*": ["models/*"],
            "@helper/*": ["helpers/*"],
            "@module/*": ["modules/*"],
            "@library/*": ["lib/*"],
            "@config/*": ["configs/*"]
        },
        "types": ["mocha", "node"],
        "esModuleInterop": true,
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true,
        "allowSyntheticDefaultImports": true,
        "resolveJsonModule": true
    },
    "exclude": ["**/dist", "**/node_modules", "**/*.spec.ts", "**/__tests__", "build", "bin", "node_modules"]
}

My build command is inside package.json is

"build": "tsc --skipLibCheck --project . --outDir ./bin",

@prabir-vora thanks for reaching out, what version of typescript are you using?

@vanGalilea Earlier I was using version 3 but it didn't work. So I upgraded to the latest version 4.7.4 but no luck.

@prabir-vora can you post the type errors that you get after upgrading to latest TS version please

Found 29 errors.

Hey @prabir-vora, I created a test project. I can find the same 29 errors if I am on typescript v3.9, but not on typescript v4.7.4. Please make sure that you have properly reinstalled typescript. After changing the package.json, run npm install or yarn again. And then run your build command again.

I believe the issue is because of TypeScript strict mode. Strict mode enforces much more stringent typing requirements. This is now default in Angular since version 14, and strict mode provides a lot of value as it brings to the surface many issues at compile time that would otherwise blow up an app at runtime.
