# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at mugo@forfuture.co.ke. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.

## 🚀 Usage
```js
const TelegramBot = require('node-telegram-bot-api');
// replace the value below with the Telegram token you receive from @BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';
// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, {polling: true});
// Matches "/echo [whatever]"
bot.onText(/\/echo (.+)/, (msg, match) => {
// 'msg' is the received Message from Telegram
// 'match' is the result of executing the regexp above on the text content
// of the message
const chatId = msg.chat.id;
const resp = match[1]; // the captured "whatever"
// send back the matched "whatever" to the chat
bot.sendMessage(chatId, resp);
});
// Listen for any kind of message. There are different kinds of
// messages.
bot.on('message', (msg) => {
const chatId = msg.chat.id;
// send a message to the chat acknowledging receipt of their message
bot.sendMessage(chatId, 'Received your message');
});

<a name="gifs"></a>
### How do I send GIFs?
You might be trying to send your animated GIFs using *TelegramBot#sendPhoto()*.
The method mostly supports static images. As noted by the community,
it seems you need to send them as documents, using *TelegramBot#sendDocument()*.
```js
bot.sendDocument(chatId, 'cat.gif');
```

## Events
*TelegramBot* is an [EventEmitter](https://nodejs.org/api/events.html#events_class_eventemitter)
that emits the following events:
1. `message`: Received a new incoming [Message][message] of any kind
1. Depending on the properties of the [Message][message], one of these
events may **ALSO** be emitted: `text`, `audio`, `document`, `photo`,
`sticker`, `video`, `voice`, `contact`, `location`,
`new_chat_members`, `left_chat_member`, `new_chat_title`,
`new_chat_photo`, `delete_chat_photo`, `group_chat_created`,
`game`, `pinned_message`, `poll`, `dice`, `migrate_from_chat_id`, `migrate_to_chat_id`,
`channel_chat_created`, `supergroup_chat_created`,
`successful_payment`, `invoice`, `video_note`
1. **Arguments**: `message` ([Message][message]), `metadata` (`{ type?:string }`)
1. `new_chat_participant`, `left_chat_participant` are **deprecated**
1. `callback_query`: Received a new incoming [Callback Query][callback-query]
1. `inline_query`: Received a new incoming [Inline Query][inline-query]
1. `chosen_inline_result`: Received result of an inline query i.e. [ChosenInlineResult][chosen-inline-result]
1. `channel_post`: Received a new incoming channel post of any kind
1. `edited_message`: Received a new version of a message that is known to the bot and was edited
1. `edited_message_text`
1. `edited_message_caption`
1. `edited_channel_post`: Received a new version of a channel post that is known to the bot and was edited
1. `edited_channel_post_text`
1. `edited_channel_post_caption`
1. `shipping_query`: Received a new incoming shipping query
1. `pre_checkout_query`: Received a new incoming pre-checkout query
1. `poll`: Received a new incoming poll
2. `poll_answer`: A user has changed their answer in a non-anonymous poll (Only polls sent by the bot)
3. `chat_member`: A chat member's status was updated in a chat
4. `my_chat_member`: The bot's chat member status was updated in a chat
5. `chat_join_request`: A request to join the chat has been sent (The bot must have the can_invite_users administrator right)
5. `polling_error`: Error occurred during polling. See [polling errors](#polling-errors).
6. `webhook_error`: Error occurred handling a webhook request. See [webhook errors](#webhook-errors).
7. `error`: Unexpected error occurred, usually fatal!
**Tip:** Its much better to listen a specific event rather than on
`message` in order to stay safe from the content.
**Tip:** Bot must be enabled on [inline mode][inline-mode] for receive some
messages.
<a name="webhooks"></a>
## WebHooks
Telegram only supports HTTPS connections to WebHooks.
Therefore, in order to set a WebHook, you will need a SSL certificate.
Since August 29, 2015 Telegram supports self-signed ones, thus, you can
generate them:
```bash
# Our private cert will be key.pem, keep this file private
$ openssl genrsa -out key.pem 2048
# Our public certificate will be crt.pem
$ openssl req -new -sha256 -key key.pem -out crt.pem
```
Once they are generated, the `crt.pem` should be uploaded, when setting up
your webhook. For example,
```js
bot.setWebHook('public-url.com', {
certificate: 'path/to/crt.pem', // Path to your crt.pem
});
```
**Note:** If you encounter an error, like
`Error: error:0906D06C:PEM routines:PEM_read_bio:no start line`,
you may want to proceed to [this issue][issue-63] for more information.
<a name="sending-files"></a>
## Sending files
The library makes it easy to get started sending files. *By default*, you
may provide a **file-path** and the library will handle reading it for you.
For example,
```js
bot.sendAudio(chatId, 'path/to/audio.mp3');
```
You may also pass in a **Readable Stream** from which data will be piped.
For example,
```js
const stream = fs.createReadStream('path/to/audio.mp3');
bot.sendAudio(chatId, stream);
```
You may also pass in a **Buffer** containing the contents of your file.
For example,
```js
const buffer = fs.readFileSync('path/to/audio.mp3'); // sync! that's sad! :-( Just making a point!
bot.sendAudio(chatId, buffer);
```
If you already have a **File ID**, you earlier retrieved from Telegram,
you may pass it in, for example:
```js
const fileId = getFileIdSomehow();
bot.sendAudio(chatId, fileId);
```
Some API methods, such as *SendPhoto*, allow passing a **HTTP URL**, that
the Telegram servers will use to download the file. For example,
```js
const url = 'https://telegram.org/img/t_logo.png';
bot.sendPhoto(chatId, url);
```
If you wish to explicitly specify the filename or
[MIME type](http://en.wikipedia.org/wiki/Internet_media_type),
you may pass an additional argument as file options, like so:
```js
const fileOptions = {
// Explicitly specify the file name.
filename: 'customfilename',
// Explicitly specify the MIME type.
contentType: 'audio/mpeg',
};
bot.sendAudio(chatId, data, {}, fileOptions);
```
**NOTE:** You **MUST** provide an empty object (`{}`) in place of
*Additional Telegram query options*, if you have **no** query options
to specify. For example,
```js
// WRONG!
// 'fileOptions' will be taken as additional Telegram query options!!!
bot.sendAudio(chatId, data, fileOptions);
// RIGHT!
bot.sendAudio(chatId, data, {}, fileOptions);
```
<a name="sending-files-options"></a>
### File Options (metadata)
When sending files, the library automatically resolves
the `filename` and `contentType` properties.
**For now, this has to be manually activated using environment
variable `NTBA_FIX_350`.**
In order of highest-to-lowest precedence in searching for
a value, when resolving the `filename`:
*(`fileOptions` is the Object argument passed to the method.
The "file" argument passed to the method can be a `Stream`,
`Buffer` or `filepath`.)*
1. Is `fileOptions.filename` explictly defined?
1. Does `Stream#path` exist?
1. Is `filepath` provided?
1. Default to `"filename"`
And the `contentType`:
1. Is `fileOptions.contentType` explictly-defined?
1. Does `Stream#path` exist?
1. Try detecting file-type from the `Buffer`
1. Is `filepath` provided?
1. Is `fileOptions.filename` explicitly defined?
1. Default to `"application/octet-stream"`
<a name="sending-files-performance"></a>
### Performance Issue
To support providing file-paths to methods that send files involves
performing a file operation, i.e. *fs.existsSync()*, that checks for
the existence of the file at the provided path. While the cost of
this operation *might* be negligible in most use cases, if you want
to squeeze the best performance out of this library, you may wish to
disable this behavior.
This will mean that you will **NOT** be able to pass in file-paths.
You will have to use Streams or Buffers to provide the file contents.
Disabling this behavior:
```js
const bot = new TelegramBot(token, {
filepath: false,
});
```
<a name="error-handling"></a>
## Error handling
Every `Error` object we pass back has the properties:
* `code` (String):
* value is `EFATAL` if error was fatal e.g. network error
* value is `EPARSE` if response body could **not** be parsed
* value is `ETELEGRAM` if error was returned from Telegram servers
* `response` ([http.IncomingMessage](https://nodejs.org/api/http.html#http_class_http_incomingmessage)):
* available if `error.code` is **not** `EFATAL`
* `response.body` (String|Object): Error response from Telegram
* type is `String` if `error.code` is `EPARSE`
* type is `Object` if `error.code` is `ETELEGRAM`
For example, sending message to a non-existent user:
```js
bot.sendMessage(nonExistentUserId, 'text').catch((error) => {
console.log(error.code); // => 'ETELEGRAM'
console.log(error.response.body); // => { ok: false, error_code: 400, description: 'Bad Request: chat not found' }
});
```
<a name="polling-errors"></a>
## Polling errors
An error may occur during polling. It is up to you to handle it
as you see fit. You may decide to crash your bot after a maximum number
of polling errors occurring. **It is all up to you.**
By default, the polling error is just logged to stderr, if you do
**not** handle this event yourself.
Listen on the `'polling_error'` event. For example,
```js
bot.on('polling_error', (error) => {
console.log(error.code); // => 'EFATAL'
});
```
<a name="webhook-errors"></a>
## WebHook errors
Just like with [polling errors](#polling-errors), you decide on how to
handle it. By default, the error is logged to stderr.
Listen on the `'webhook_error'` event. For example,
```js
bot.on('webhook_error', (error) => {
console.log(error.code); // => 'EPARSE'
});
```
