OpenAPI Node.js
Code Generator
Use your API OpenAPI 3.x/Swagger 2 definition to generate Node.js ES7-compliant code for your API.
The generated code features:
* ES7
* ESLint
* YAML config file
* Express
* No transpiling
## Install
To use it from the CLI:
```bash
npm install -g swagger-node-codegen
```
To use it as a module in your project:
```bash
npm install --save swagger-node-codegen
```
## Usage
### From the command-line interface (CLI)
```bash
Usage: snc [options]
Options:
-V, --version output the version number
-o, --output directory where to put the generated files (defaults to current directory)
-t, --templates directory where templates are located (defaults to internal nodejs templates)
-h, --help output usage information
```
#### Examples
The shortest possible syntax:
```bash
snc swagger.yaml
```
Specify where to put the generated code:
```bash
snc swagger.yaml -o ./my-api
```
### As a module in your project
```js
const path = require('path');
const codegen = require('swagger-node-codegen');
const swagger = require('./swagger.json');
codegen.generate({
swagger,
target_dir: path.resolve(__dirname, './my-api')
}).then(() => {
console.log('Done!');
}).catch(err => {
console.error(`Something went wrong: ${err.message}`);
});
```
The `swagger` parameter can be either JSON or a path pointing to a JSON or YAML file.
```js
const path = require('path');
const codegen = require('swagger-node-codegen');
codegen.generate({
swagger: path.resolve(__dirname, './swagger.yml'),
target_dir: path.resolve(__dirname, './my-api')
}).then(() => {
console.log('Done!');
}).catch(err => {
console.error(`Something went wrong: ${err.message}`);
});
```
#### Using async/await
The function `codegen.generate` returns a Promise, so it means you can use async/await:
```js
const path = require('path');
const codegen = require('swagger-node-codegen');
try {
await codegen.generate({
swagger: path.resolve(__dirname, './swagger.yml'),
target_dir: path.resolve(__dirname, './my-api')
});
console.log('Done!');
} catch (err) {
console.error(`Something went wrong: ${err.message}`);
}
```
