---
### INSTALL
```npm install check-esm --save```
---
### USAGE
ESM Module
`import { _isESCode } from "check-esm";`
CommonJS Script/ Module
```
const checkEsm = require("check-esm");`
isESCode("./path/to/file.mjs")
```

### Package APIs
There are other script APIs you may wish to explore that includes the following:
#### `.checkModuleImports`
Check if a module can be imported using `import()`
Usage:
`.checkModuleImports(absPath)`
#### `.requiresObject`
Check require.cache list in code - used in your code's process global context.
Usage:
`.requiresObject()`
#### `.requireRegex`
Check to see if there are `require()` syntax in code.
Usage:
`.requireRegex(absPath, basePath = "", useProcessCwd = false)`
`.requireRegex(absPath)`
#### `.importRegex`
Check to see if there are `import()` syntax in code.
Usage:
`.importRegex(absPath, basePath = "", useProcessCwd = false)`
`.importRegex(absPath)`
#### `.importESRegex`
Check to see if there are `import x from ""` syntax in code.
Usage:
`.importESRegex(absPath, basePath = "", useProcessCwd = false)`
`.importESRegex(absPath)`
#### `.importRegexExtended`
Check to see if there are `import()` syntax in code.
Usage:
`.importRegexExtended(absPath, basePath = "", useProcessCwd = false)`
`.importRegexExtended(absPath)`
#### `.isESMFileExtension`
Check to see if the file has `.mjs`/ `.cjs`/ `.js` extension.
Usage:
`.isESMFileExtension(absPath)`
#### `.isNodeCompatibleFileExtension`
Check to see if the file has `.mjs`/ `.cjs`/ `.js` / `.node` / `.wasm` extension.
Usage:
`.isNodeCompatibleFileExtension(absPath)`
#### `.isESMCodeBase`
Check to see if the code is ESM Module.
Usage:
`.isESMCodeBase(absPath)`
#### `isCJSCodeBase`
Check to see if the code is CommonJS Script or Module.
Usage:
`isCJSCodeBase(absPath)`
#### `isModuleInPackageJson`
Checks type key's value in package.json.
Usage:
`getPackageJsonRoot(startdirectory, options)`
#### `isESCode`
Multiple checks to check if the code is ESM Module (other than package.json type key's value check in package.json).
Usage:
`isModuleInPackageJson(absPath, packagejsonPath, returns)`
