# Dependency Injection (IoC) example ([ioc](https://github.com/alexindigo/ioc))
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-ioc with-ioc-app
|
|
# or
|
|
yarn create next-app --example with-ioc with-ioc-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-ioc
|
|
cd with-ioc
|
|
```
|
|
|
|
Install it and run:
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```
|
|
|
|
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download))
|
|
|
|
```bash
|
|
now
|
|
```
|
|
|
|
## The idea behind the example
|
|
|
|
This example uses [ioc](https://github.com/alexindigo/ioc) for dependency injection, which lets you create decoupled shared components and keep them free from implementation details of your app / other components.
|
|
|
|
It builds on top of [with-next-routes](https://github.com/zeit/next.js/tree/master/examples/with-next-routes) example and makes use of dependency injection to propagate custom `Link` component to other components.
|
|
|
|
Also, it illustrates ergonomics of testing using dependency injection.
