how to use the ensuresymlinksync function from the fs-extra library in typescript

The ensuresymlinksync function from the fs-extra library can be used to create a symbolic link if it doesn't exist or ensure that it points to the correct target if it already exists. The function is synchronous and returns void. Here is an example of how to use it in TypeScript:

index.ts
import { ensureSymlinkSync } from 'fs-extra';

const targetPath = '/path/to/target';
const symlinkPath = '/path/to/symlink';

// Ensure that symlink points to target
ensureSymlinkSync(targetPath, symlinkPath);
210 chars
8 lines

In the example above, ensureSymlinkSync takes two arguments: the targetPath which is the path to the target file or directory that the symlink should point to, and the symlinkPath which is the path to the symbolic link file to be created. The function checks if a symbolic link already exists at symlinkPath and ensures that it points to the correct target. If there is no symbolic link at the path given by symlinkPath, the function creates a new one that points to targetPath.

Note that the ensureSymlinkSync function is synchronous and may block the event loop, so it's best to use it when performance is not an issue or when dealing with small files.
