## What you get!

- [Express.js](http://www.expressjs.com) - Fast, unopinionated
, minimalist web framework for Node.js
- [Babel.js](https://babeljs.io/) - Use new syntax, right now without waiting for support
- [Pino](https://github.com/pinojs/pino) - Extremely fast node.js logger, inspired by Bunyan. It also includes a shell utility to pretty-print its log files
- [dotenv](https://github.com/motdotla/dotenv) - Loads environment variables from .env for nodejs projects
- [ESLint](http://eslint.org/) - a pluggable linting utility for JavaScript and JSX

Choose from the following ESLint lint rules:

- [Airbnb](https://github.com/airbnb/javascript) - A mostly reasonable approach to JavaScript
- [Prettier](https://github.com/prettier/prettier) - Prettier is an opinionated code formatter

- [Swagger](http://swagger.io/) - is a simple yet powerful representation of your RESTful API
- [SwaggerUI](http://swagger.io/) - dynamically generate beautiful documentation and sandbox from a Swagger-compliant API

### API Validation

Simply describe your APIs with Swagger and automagically get for free:

- Interactive documentation
- API request validation
- API response validation (OpenAPI 3 only. Disabled by default)
- To enable set `OPENAPI_ENABLE_RESPONSE_VALIDATION=true` in `.env`

#### Interactive API Doc

![](https://raw.githubusercontent.com/cdimascio/generator-express-no-stress/master/assets/interactive-doc1.png)

#### API Validation!

Oops! I the API caller forgot to pass a `name` field, no stress, we've got this!

### Structured Logging

Structured logging out of the box!

#### raw

![](https://raw.githubusercontent.com/cdimascio/generator-express-no-stress/master/assets/logging-raw.png)

#### pretty

Structured logging pretty printed by default - great for dev!

### Linting

express-no-stress uses [ESLint](http://eslint.org/) and provides two choices, Airbnb or Prettier.

To add your own ESLint customizations, edit`.eslintrc.json`.

Note that the Airbnb variant provides a slightly modified Airbnb [base](https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb-base) configuration.

## FAQ
**Q**: How do I modify the example API and make it my own?

**A**: There are two key files that enable you to customize and describe your API:
1. `server/routes.js` - This references the implementation of all of your routes. Add as many routes as you like and point each route your express handler functions.
2. `server/common/api.yaml` - This file contains your [OpenAPI spec](https://swagger.io/specification/). Describe your API here. It's recommended that you to declare any and all validation logic in this YAML. `express-no-stress-typescript` uses [express-openapi-validator](https://github.com/cdimascio/express-openapi-validator) to automatically handle all API validation based on what you've defined in the spec.

**Q**: I previously generated an app, but I want to change the API root. How do I do this?

**A**: You need to make to small changes
1. Modify `server/routes.js`
```javascript
// Change your original path e.g. /api/v1/examples, to:
app.use('/api/v2/examples', examplesRouter);
```

2. Modify `server/common/api.yaml` and update the api root:
```yaml
# Change e.g. /api/v1 to /api/v2
servers:
- url: /api/v2
```
