📖 [SDK API Docs](https://circleci-public.github.io/circleci-config-sdk-ts/)

---

### Installation

Using npm:

```shell
$ npm i @circleci/circleci-config-sdk
```

Using yarn:

```shell
$ yarn add @circleci/circleci-config-sdk
```

#### Usage

In Browser:

```typescript
import CircleCI from '@circleci/circleci-config-sdk';
```

In Node.js:

```javascript
const CircleCI = require('@circleci/circleci-config-sdk');
```

### Example

Generate a CircleCI config using TypeScript/Javascript, properly typed for full
IntelliSense support.

```typescript
const CircleCI = require('@circleci/circleci-config-sdk');
// Instantiate new Config
const myConfig = new CircleCI.Config();
// Create new Workflow
const myWorkflow = new CircleCI.Workflow('myWorkflow');
myConfig.addWorkflow(myWorkflow);

// Create an executor instance
// Executors are used directly in jobs
// and do not need to be added to the config separately
const nodeExecutor = new CircleCI.executors.DockerExecutor('cimg/node:lts');

// Create Job and add it to the config
const nodeTestJob = new CircleCI.Job('node-test', nodeExecutor);
myConfig.addJob(nodeTestJob);

// Add steps to job
nodeTestJob
  .addStep(new CircleCI.commands.Checkout())
  .addStep(
    new CircleCI.commands.Run({
      command: 'npm install',
      name: 'NPM Install',
    }),
  )
  .addStep(
    new CircleCI.commands.Run({
      command: 'npm run test',
      name: 'Run tests',
    }),
  );

// Add Jobs to Workflow
myWorkflow.addJob(nodeTestJob);

// The `stringify()` function on `CircleCI.Config` will return the CircleCI YAML equivalent.
const MyYamlConfig = myConfig.stringify();

// Save the config to a file in Node.js or the browser. Note, use in the browser requires user interaction.
myConfig.writeFile('config.yml');
```

`MyYamlConfig` will hold the following string (A valid CircleCI Config).

```yaml
version: 2.1
setup: false
jobs:
  node-test:
    docker:
      - image: cimg/node:lts
    resource_class: medium
    steps:
      - checkout: {}
      - run:
          command: npm install
          name: NPM Install
      - run:
          command: npm run test
          name: Run tests
workflows:
  myWorkflow:
    jobs:
      - node-test: {}
```
