Bunyan stream for Slack chat integration
First install bunyan...
npm install bunyan
Then install bunyan-slack
npm install bunyan-slack
##Basic Setup
var bunyan = require("bunyan"),
BunyanSlack = require('bunyan-slack'),
log;
log = bunyan.createLogger({
name: "myApp",
stream: new BunyanSlack({
webhook_url: "your_webhook_url",
channel: "your_channel",
username: "your_username",
}),
level: "error"
});
log.error("hello bunyan slack");
You can also pass an optional error handler.
new BunyanSlack({
webhook_url: "your_webhook_url",
channel: "your_channel",
username: "your_username",
}, function(error){
console.log(error);
});
##Custom Formatters
By default the logs are formatted like so: [LOG_LEVEL] message
, unless you specify a customFormatter
function.
log = bunyan.createLogger({
name: "myApp",
stream: new BunyanSlack({
webhook_url: "your_webhook_url",
channel: "your_channel",
username: "your_username",
customFormatter: function(record, levelName){
return {text: "[" + levelName + "] " + record.msg }
}
}),
level: "error"
});
##Custom Formatter Options
Formatting options below are taken from the slack docs
For a simple message, your JSON payload must contain a text property. This is the text that will be posted to the channel.
{
"text": "This is a line of text.\nAnd this is another one."
}
This will be displayed in the channel as:
###Adding Links
To create a link in your text, enclose the URL in <> angle brackets. For example: payload={"text": "<https://slack.com>"}
will post a clickable link to https://slack.com.
To display hyperlinked text instead of the actual URL, use the pipe character, as shown in this example:
{
"text": "<https://alert-system.com/alerts/1234|Click here> for details!"
}
This will be displayed in the channel as:
###Customized Name and Icon
You can override an incoming webhook's configured name with the username
parameter in your JSON payload.
You can also override the bot icon either with icon_url
or icon_emoji
.
{
"username": "new-bot-name",
"icon_url": "https://slack.com/img/icons/app-57.png",
"icon_emoji": ":ghost:"
}
An overridden username and icon could look like this:
###Channel Override
Incoming webhooks have a default channel. You can override it with the channel
parameter in your JSON payload.
A public channel can be specified with "channel": "#other-channel"
, and a Direct Message with "channel": "@username"
.
{
"channel": "#other-channel", // A public channel override
"channel": "@username", // A Direct Message override
}
###Defaults bunyan-slack sets the following defaults:
channel
=>"#general"
username
=>"Bunyan Slack"
icon_emoji
=>":scream_cat:"
###Advanced Message Formatting You can use Slack's standard message markup to add simple formatting to your messages. You can also use message attachments to display richly-formatted message blocks.
###Putting it all together
var bunyan = require("bunyan"),
BunyanSlack = require('bunyan-slack'),
log;
log = bunyan.createLogger({
name: 'myapp',
stream: new BunyanSlack({
webhook_url: 'your_webhook_url',
icon_url: "your_icon_url",
channel: 'your_channel',
username: "your_username",
icon_emoji: ":scream_cat:",
customFormatter: function(record, levelName) {
return {
attachments: [{
fallback: "Required plain-text summary of the attachment.",
color: '#36a64f',
pretext: "Optional text that appears above the attachment block",
author_name: "Seth Pollack",
author_link: "http://sethpollack.net",
author_icon: "http://www.gravatar.com/avatar/3f5ce68fb8b38a5e08e7abe9ac0a34f1?s=200",
title: "Slack API Documentation",
title_link: "https://api.slack.com/",
text: "Optional text that appears within the attachment",
fields: [{
title: "We have a new " + levelName + " log",
value: ":scream_cat: " + record.msg,
short: true
}]
}]
};
}
}),
level: 'error'
});
