Examples

ATTENTION - NOT AVAILABLE NOW: Sending messages to specific chats

{
    "plugins": [
        "@semantic-release/commit-analyzer",
        "@semantic-release/release-notes-generator",
        [
            "semantic-release-telegram-bot",
            {
                "success": {
                    "message": "Here is the new release!"
                },
                "notifications": [
                    {
                        "chatIds": "PrivateChatId",
                        "notifyOnFail": true,
                        "notifyOnSuccess": false,
                        "fail": {
                            "message": "Oops!"
                        }
                    },
                    {
                        "chatIds": "PrivateChatId",
                        "branch": "rc/*"
                    },
                    {
                        "chatIds": "PublicChatId",
                        "branch": "release/*"
                    }
                ]
            }
        ]
    ]
}

In this example:

• Failure messages from all branches will be sent to PrivateChatId chat, also the messages changed to Oops!
• Success messages from rc branches will be sent to PrivateChatId chat
• Only a success message from release branches will be sent to PublicChatId chat
• All success messages changed to Here is the new release!

Custom inline template

Here is an example of the inline template, it uses template function from lodash to render your message.

{
    "plugins": [
        "@semantic-release/commit-analyzer",
        "@semantic-release/release-notes-generator",
        [
            "semantic-release-telegram-bot",
            {
                "success": {
                    "message": "Here is a new release of ${packageName} library and value ${myVariable} of my custom variable",
                    "customData": {
                        "myVariable": "myVariable"
                    }
                }
            }
        ]
    ]
}

Custom template

Be careful when describing your templates, you must support html or markdown telegram syntax.

Look at the nunjucks docs to see what functionality you can use

<!--custom-success-template.html-->

<b>A new version of {{packageName}} has been released!</b>

Custom change log:

{% for commit in commits %}
• ({{ commit.subject }}): {{ commit.message }}
{% endfor %}

And specify the path to the template

{
    "plugins": [
        "@semantic-release/commit-analyzer",
        "@semantic-release/release-notes-generator",
        [
            "semantic-release-telegram-bot",
            {
                "success": {
                    "path": "./path/to/custom-success-template.html"
                }
            }
        ]
    ]
}
