This is the typescript definition generator for the java-bridge package. It generates typescript definitions for java classes and interfaces.

It can either be invoked from the command line or used as a library.

Note: You need to install java-bridge separately

npm install -g java-ts-definition-generator java-bridge

java-ts-gen <output> <classnames..>

Positionals:
  classnames  The fully qualified class name(s) to convert              [string]
  output      The output file                                           [string]

Options:
  --help             Show help                                         [boolean]
  --version          Show version number                               [boolean]
  --classpath, --cp  The classpath to use                               [string]

• The classpath argument can be supplied multiple times to add multiple jars to the classpath
• Multiple class names can be supplied to generate definitions for multiple classes
• The generated typescript files will automatically import all classes once the module is loaded.

Generate definitions for the java.lang.String class and all its referenced classes and save them to ./project:

java-ts-gen ./project java.lang.String

This will create a directory called java containing the definitions for the java.lang.String class and all its dependencies all inside subdirectories. The java.lang.String class will be saved to ./project/java/lang/String.ts. Thus, the folder structure of project will look something like this:

.
├── ...
├── java
│   ├── lang
│   │   ├── String.ts
│   │   ├── Object.ts
│   │   └── ...
│   ├── util
│   │   └── ...
│   └── ...
└── ...

Generate definitions for the java.lang.String and java.util.ArrayList classes and all of their dependencies and save them to ./project:

java-ts-gen ./project java.lang.String java.util.ArrayList

import { TypescriptDefinitionGenerator } from 'java-ts-definition-generator';

const generator = new TypescriptDefinitionGenerator('java.lang.String');
// Generate the typescript definitions
const definitions = await generator.generate();

// Save the definitions to a directory
await TypescriptDefinitionGenerator.save(definitions, './project');

const generator = new TypescriptBulkDefinitionGenerator();

// Generate definitions for the provided modules
await generator.generate([
    'java.lang.String',
    'java.util.List',
    'java.util.Map',
    'java.io.FileOutputStream',
    'java.io.FileInputStream',
    'java.io.File',
    'java.lang.System',
]);

// Save the definitions to a directory
await generator.save('javaDefinitions');
