Defender Autotask Client
The Defender Autotasks service allows you to run small code snippets on a regular basis or via webhooks that can make calls to the Ethereum network or to external APIs. Thanks to tight integration to Defender Relayers, you can use Autotasks to automate regular actions on your contracts.
This client allows you to update the code of your Autotasks programmatically, so you don't need to copy-paste code into the Defender web application. Additionally, the client allows you to easily create, list, retrieve, delete and update your Autotasks.
Example usage:
$ defender-autotask update-code 19ef0257-bba4-4723-a18f-67d96726213e ./lib/my-autotask
Install
npm install defender-autotask-client
yarn add defender-autotask-client
Usage
The client can be used either programmatically as part of a script, or directly via the command line. Both uses require a Defender Team API Key. Create one on the top-right menu in the Defender web application, and grant to it the capability to manage autotask code.
Keep in mind that your Autotask code should include an index.js
javascript file with an entrypoint, such as the following. You may also require
other files you include in the bundle.
exports.handler = async function () {
/* your code here */
};
Note that you can only use the client to update the code of an existing Autotask.
Command line
Set the environment variables API_KEY
and API_SECRET
to the Team API key/secret you created on Defender, and invoke the defender-autotask
bin:
$ defender-autotask update-code $AUTOTASK_ID $PATH_TO_CODE
$ defender-autotask execute-run $AUTOTASK_ID
$ defender-autotask tail-runs $AUTOTASK_ID
Beware that the defender-autotask
CLI will automatically load environment variables from a local .env
file if found.
Note: In order to get the CLI to work, it should've been installed globally, otherwise, you can prefix with npx
if you're using it directly on bash. This is not necessary when running from your package.json
defined scripts.
Script usage
Use the Team API key to initialize an instance of the Defender Autotask client:
const { AutotaskClient } = require('defender-autotask-client');
const client = new AutotaskClient({ apiKey: API_KEY, apiSecret: API_SECRET });
List
To list your current autotasks, simply call the list
function.
await client.list();
Create
To create a new autotask, construct an CreateAutotaskRequest
object.
interface CreateAutotaskRequest {
name: string;
encodedZippedCode: string;
relayerId?: string;
trigger: {
type: 'schedule' | 'webhook',
frequencyMinutes?: number,
cron?: string,
};
paused: boolean;
}
And pass down the object to the create
function.
const myAutotask: CreateAutotaskRequest = { name: "myAutotask", paused: false, ... };
await client.create(myAutotask);
Retrieve
To retrieve one of your autotask, call the get
function with the autotask Id.
await client.get('671d1f80-99e3-4829-aa15-f01e3298e428');
Update
To update an existing autotask, construct an UpdateAutotaskRequest
object.
interface UpdateAutotaskRequest {
autotaskId: string;
name: string;
encodedZippedCode?: string;
relayerId?: string;
trigger: {
type: 'schedule' | 'webhook',
frequencyMinutes?: number,
cron?: string,
};
paused: boolean;
}
And pass down the object to the update
function.
const myAutotask: UpdateAutotaskRequest = { name: "myAutotask-V2", paused: true, ... };
await client.update(myAutotask);
Delete
To delete one of your autotask, call the delete
function with the autotask Id.
await client.delete('671d1f80-99e3-4829-aa15-f01e3298e428');
Update Code
To update the code of an existing Autotask, zip it and upload it using the client, providing the ID of the Autotask to update:
const zip = fs.readFileSync('code.zip');
await client.updateCodeFromZip(autotaskId, zip);
Alternatively, you can also choose a folder to upload, and the client will take care of zipping it and uploading it:
await client.updateCodeFromFolder(autotaskId, './path/to/code');
You can also provide the set of files and their content, and the client will generate and upload the zip file for you:
await client.updateCodeFromSources(autotaskId, {
'index.js': 'exports.handler = function() { return 42; }',
});
Autotask Runs
To execute an autotask run, execute the command below substituting the autotaskId
:
await client.runAutotask(autotaskId);
You can list all runs for an autotask with the following command:
await client.listAutotaskRuns(autotaskId);
And get detailed logs for a single run using the autotaskRunId
(returned in the listAutotaskRuns
response directly above):
await client.getAutotaskRun(autotaskRunId);
FAQ
How do I find the ID of my Autotask?
You can retrieve it from the Edit Code page of your Autotask, or directly from the URL. For instance, in the following URL, the ID is 19ef0257-bba4-4723-a18f-67d96726213e
.
