Why is tslint:recommended not allowing modules?

Question

We are using typescript v2.3.2 and TSLint v4.5.1 with VS Code to create a SPA. Codebase is growing and we need to modularize it someway.

I tried to do the modularization using typescript modules but found the following lint error when transpiling the app.

[tslint] 'namespace' and 'module' are disallowed (no-namespace) 

I'm using this configuration for the linter:

{   "extends": "tslint:recommended",   "rules": {     "no-var-requires": false,     "no-console": ["error", false],     "max-line-length": [false]   } } 

The recommended rules file at line 89 shows this rule:

"no-namespace": true, 

I wonder if there is something wrong and what would be the best way to modularize a SPA, following good practices that are not obsolete soon.

Examples of code will be welcomed. Thank you very much.

[tslint] 'namespace' and 'module' are disallowed (no-namespace)

Because the are not standard JavaScript syntax.

• Namespace is a special TypeScript only syntax for a common JS pattern : https://basarat.gitbook.io/typescript/docs/project/namespaces.html
• Do not use namespaces with outFile : https://basarat.gitbook.io/typescript/docs/tips/outFile.html
