# EdgeGrid for Node.js

![Build Status](https://github.com/akamai/AkamaiOPEN-edgegrid-node/actions/workflows/test.yml/badge.svg)

This library implements an Authentication handler for the Akamai EdgeGrid Authentication scheme in Node.js for Node v14 and above.

You can find the most up-to-date package in [NPM](https://www.npmjs.com/package/akamai-edgegrid) under `akamai-edgegrid`.

## Install

`npm install --save akamai-edgegrid`

## Authentication

You can obtain the authentication credentials through an API client. Requests to the API are marked with a timestamp and a signature and are executed immediately.

1. [Create authentication credentials](https://techdocs.akamai.com/developer/docs/set-up-authentication-credentials).

2. Place your credentials in an EdgeGrid file `~/.edgerc`, in the `[default]` section.

    ```
    [default]
    client_secret = C113nt53KR3TN6N90yVuAgICxIRwsObLi0E67/N8eRN=
    host = akab-h05tnam3wl42son7nktnlnnx-kbob3i3v.luna.akamaiapis.net
    access_token = akab-acc35t0k3nodujqunph3w7hzp7-gtm6ij
    client_token = akab-c113ntt0k3n4qtari252bfxxbsl-yvsdj
    ```

3. Use your local `.edgerc` by providing the path to your resource file and credentials' section header.

    ```javascript
    var eg = new EdgeGrid({
      path: '/path/to/.edgerc',
      section: '<section-header>'
    });
    ```

    Alternatively, you can hard code your credentials by passing the credential values to the `EdgeGrid()` method.

    ```javascript
    var clientToken = "akab-c113ntt0k3n4qtari252bfxxbsl-yvsdj",
        clientSecret = "C113nt53KR3TN6N90yVuAgICxIRwsObLi0E67/N8eRN=",
        accessToken = "akab-acc35t0k3nodujqunph3w7hzp7-gtm6ij",
        baseUri = "akab-h05tnam3wl42son7nktnlnnx-kbob3i3v.luna.akamaiapis.net";

    var eg = new EdgeGrid(clientToken, clientSecret, accessToken, baseUri);
    ```

## Use

To use the library, provide the path to your `.edgerc`, your credentials section header, and the appropriate endpoint information.

```javascript
var EdgeGrid = require('akamai-edgegrid');

var eg = new EdgeGrid({
  path: '/path/to/.edgerc',
  section: 'section-header'
});

eg.auth({
  path: '/identity-management/v3/user-profile',
  method: 'GET',
  headers: {
    'Accept': "application/json"
  },
  body: {}
});

eg.send(function(error, response, body) {
  console.log(body);
});
```

### Chaining

You can also chain calls by combining the execution of `auth` and `send` methods.

```javascript
eg.auth({
  path: '/identity-management/v3/user-profile',
  method: 'GET',
  headers: {},
  body: {}
}).send(function (error, response, body) {
  console.log(body);
});
```

### Query string parameters

When entering query parameters use the `qs` property under the `auth` method. Set up the parameters as name-value pairs in a object.

```javascript
eg.auth({
    path: '/identity-management/v3/user-profile',
    method: 'GET',
    headers: {},
    qs: {
        authGrants: true,
        notifications: true,
        actions: true
    },
    body: {}
})
```

### Headers

Enter request headers as name-value pairs in an object.

> **Note:** You don't need to include the `Content-Type` and `Content-Length` headers. The authentication layer adds these values.

```javascript
eg.auth({
  path: '/identity-management/v3/user-profile',
  method: 'GET',
  headers: {
    'Accept': "application/json"
  }
});
```

### Body data

Provide the request body as an object or as a POST data formatted string.

```javascript
// Object
eg.auth({
    path: '/identity-management/v3/user-profile/basic-info',
    method: 'PUT',
    headers: {},
    body: {
        contactType: "Billing",
        country: "USA",
        firstName: "John",
        lastName: "Smith",
        phone: "3456788765",
        preferredLanguage: "English",
        sessionTimeOut: 30,
        timeZone: "GMT"
   }
});
```

### Encoding

When interacting with binary data, such as during the retrieval of PDF invoices, specify the `responseType` as an `arraybuffer` in the `auth` method call. Omitting the `responseType` will cause an unreadable or blank response.

```javascript
const fs = require('fs');

eg.auth({
  path : `/invoicing-api/v2/contracts/${contractId}/invoices/${invoiceNumber}/files/${fileName}`,
  method: 'GET',
  responseType: 'arraybuffer', // Important
}).send((err, response) => {
  if (err) {
    return console.log(err);
  }
  fs.writeFile(`./${fileName}`, response.data, 'binary', (err) => {
    if (err){
      return console.log(err);
    }
    console.log('File was saved!');
  });
});
```

### Proxy

To use edgegrid with proxy, you can configure it with one of these methods:

- Add the `proxy` argument to the `EdgeGrid()` method.

  ```javascript
  eg.auth({
    path : `/identity-management/v3/user-profile`,
    method: 'GET',
    proxy: {
      host: 'my.proxy.com',
      protocol: "https",
      port: 3128,
      auth: {
        username: 'my-user',
        password: 'my-password'
      }
    }
  }).send((err, response) => {
    if (err) {
      return console.log(err);
    }
    console.log('Success!');
    // Do something with the response
  });
  ```

- Set the `HTTPS_PROXY` environment variable.

  ```shell
  $ export HTTPS_PROXY=https://username:password@host:port
  $ node myapp.js
  ```

### Debug

Enable debugging to get additional information about a request. You can configure this with one of these methods:

- Add the `debug` argument to the `EdgeGrid()` method.

  ```javascript
  var eg = new EdgeGrid({
    path: '/path/to/.edgerc',
    section: 'section-header'
    debug: true
  });
  ```

- Set the `EG_VERBOSE` environment variable.

  ```shell
  $ export EG_VERBOSE=true
  $ node src/main.js
  ```
