Require statement not part of import statement.

Error message

Require statement not part of import statement.

What it means

Raised by typescript/no_var_requires when a `require(...)` call (a global CommonJS require, per is_global_require_call) is assigned to a variable via `var`/`let`/`const` or otherwise used outside an import statement. At the throw site the code mixes CommonJS require into a TS module where TypeScript conventions (and `import = require` for types) apply; plain require bypasses type resolution and module semantics. no_var_requires_diagnostic fires from run() for each standalone require-call assignment.

Solutions

1. Use `import fs from "fs"` instead.
2. For types-only imports needing the pattern, use `import x = require("...")`.
