## LexicalModelCompiler class
Compiles a .model.ts file to a .model.js. The compiler does not read or write from filesystem or network directly, but relies on callbacks for all external IO.
**Signature:**
```typescript
export declare class LexicalModelCompiler implements KeymanCompiler
```
**Implements:** KeymanCompiler
## Methods
| Method | Modifiers | Description |
| --- | --- | --- |
| [init(callbacks, \_options)](./kmc-model.lexicalmodelcompiler.init.md) | | Initialize the compiler. There are currently no options specific to the lexical model compiler |
| [run(inputFilename, outputFilename)](./kmc-model.lexicalmodelcompiler.run.md) | | Compiles a .model.ts file to .model.js. Returns an object containing binary artifacts on success. The files are passed in by name, and the compiler will use callbacks as passed to the [LexicalModelCompiler.init()](./kmc-model.lexicalmodelcompiler.init.md) function to read any input files by disk. |
| [write(artifacts)](./kmc-model.lexicalmodelcompiler.write.md) | | Write artifacts from a successful compile to disk, via callbacks methods. The artifacts written may include:
- .model.js file - Javascript lexical model for web and touch platforms
