# CircleCi API Client

A Node and Browser client for the CircleCI API, written in TypeScript.

API wrapper for [CircleCi API](https://circleci.com/docs/api/v1-reference/), usable in node and the browser. If used in a TypeScript project, you will get types, and auto-complete for all of the api responses. You will no longer need to tab back and fourth to the API documentation.

I recommend using this library if you are writing a tool or website in TypeScript. I have created definitions for each of the CircleCI endpoints. There may still be some errors, but I am open to contributions on making them better.

If there are any features you would like, please feel free to open up an issue.

## Notes

### Types

I did my best to correctly add types for all of the supported endpoints. However if you notice an incorrect payload type, or some missing properties, **please** open up an issue, or submit a pull request.

### CircleCI API v2

CircleCI is going to be rolling out a new version of their api (see [here](https://github.com/CircleCI-Public/api-preview-docs)). Currently this library **does not** support v2, but I will update it in the future, see [#228](https://github.com/worldturtlemedia/circleci-api/issues/228) for updates.

## Migrating from v3 to v4

There have been some breaking changes, please see [MIGRATING.md](https://github.com/worldturtlemedia/circleci-api/blob/master/MIGRATING.md) for more info.

## Installation

Add using yarn or npm

```bash
yarn add circleci-api

## or

npm install circleci-api
```

## Usage

Get your API token from [CircleCi](https://circleci.com/account/api)

There are two ways to use this library.

## 1. CircleCi class

Get instance of the factory.

```typescript
// Module
import { CircleCI, GitType, CircleCIOptions } from "circleci-api";

// Configure the factory with some defaults
const options: CircleCIOptions = {
  // Required for all requests
  token: "", // Set your CircleCi API token

// Optional
  // Anything set here can be overriden when making the request

// Git information is required for project/build/etc endpoints
  vcs: {
    type: GitType.GITHUB, // default: github
    owner: "worldturtlemedia",
    repo: "circleci-api"
  }

// Optional query params for requests
  options: {
    branch: "master", // default: master
    filter: "completed"
  }
}

// Create the api object
const api = new CircleCI(options)

// Use the api

/**
 * Grab the latest artifacts from a successful build on a certain branch
 * @param [branch="master"] - Artifacts for certain branch
 * @return List of successfully built artifact objects
 */
export async function getLatestArtifacts(branch: string = "master"): Promise<Artifact[]> {
  try {
    // Will use the repo defined in the options above
    const result: Aritfact[] = await api.latestArtifacts({ branch, filter: "successful" })
    console.log(`Found ${result.length} artifacts`)
    return result
  } catch (error) {
    console.log("No build artifacts found")
  }

return []
}

getLatestArtifacts("develop")
  .then(artifacts => {
    artifacts
      .forEach(({ path, url }: Artifact) => console.log(`${path} -> ${url}`))
  })

// Or override settings set above
api
  .latestArtifacts(
    { branch: "develop" },
    {
      vcs: { repo: "awesome-repo" },
      options: { filter: "successful" }
    }
  )
  .then((artifacts: Artifact[]) => console.log(`Found ${artifacts.length} artifacts`))
  .catch(error => console.error(error))
```

## 2. Manually

The individual functions can also be imported if you only need one or two. To help with tree-shaking.

```typescript
import { getMe, getLatestArtifacts } from "circleci-api";

const CIRCLECI_TOKEN: string = "circle-ci-token";

getMe(CIRCLECI_TOKEN)
  .then(me => console.log("token is valid"))
  .catch(error => console.error("invalid token"));

getLatestArtifacts(CIRCLECI_TOKEN, {
  vcs: {
    owner: "billyBob",
    repo: "super-cool-app"
  },
  options: {
    filter: "failed",
    branch: "feature-smith2"
  }
})
  .then(result => console.log(`Found ${result.length} artifacts`))
  .catch(error => console.error(error));
```

## Self-hosted CircleCI

To override the default API base url `https://circleci.com/api/v1.1`, you can pass a `circleHost` to the `CircleCI` constructor, or to the standalone functions.

```typescript
// Using the CircleCi class
new CircleCI({
  token: "my-token",
  vcs: { owner: "worldturtlemedia", repo = "circleci-api" },
  circleHost: "https://my-selfhosted-circleci.com/"
}).getLatestArtifacts()

// Using the standalone functions
getLatestArtifacts("my-token", {
  ...
  circleHost: "https://my-selfhosted-circleci.com/"
})
```

While all of the standalone functions support a custom `circleHost` property. Using the `CircleCI` class you _must_ specify it in the constructor.

## Demo

There are three similar demos are available in the `demo` folder.

**Note:** I recommend [VSCode](https://code.visualstudio.com/) for viewing and editing the examples. It will give you great intellisense about the library.

For the TypeScript & JavaScript follow the steps below:

```bash
# Step 1 - Change into demo folder and install dependencies
cd demo
yarn

# Javascript example:
node ./index.js

# Typescript example:
npx ts-node --project ../tsconfig.base.json ./index.ts

# To view Browser example, first build project
yarn build

# Then open `index.html` in your browser
```

## Supported endpoints

Using factory:

Optional properties:

```typescript
export interface CircleRequest {
  token?: string;
  vcs?: GitInfo;
  options?: Options;
}
```

Any function with an _optional_ paramater of `CircleRequest` can override any of the values you assigned when using the `circleci()` factory.

## Missing endpoint

The last remaining endpoint probably won't be added unless there is demand.

| Name              |                              Link                               |
