Developers Pipedream

Getting Started

This integration creates a workflow with a GitLab trigger and Node action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Select this integration
  2. Configure the New Review Request (Instant) trigger
    1. Connect your GitLab account
    2. Select a Project ID
  3. Configure the Run Node Code action
    1. Connect your Node account
  4. Deploy the workflow
  5. Send a test event to validate your setup
  6. Turn on the trigger

Details

This integration uses pre-built, source-available components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger

Description:Emit new event when a reviewer is added to a merge request
Version:0.1.2
Key:gitlab-new-review-request

GitLab Overview

The GitLab API provides programmatic access to your GitLab projects, allowing you to automate common tasks, manage issues, merge requests, and more. With the GitLab API on Pipedream, you can create customized workflows that integrate with other services, streamline your development process, and enhance project management. By leveraging the power of serverless, you can set up triggers for GitLab events and perform actions across a variety of apps without managing infrastructure.

Trigger Code

import base from "../common/base.mjs";
import { eventTypes } from "../common/hook-events.mjs";

export default {
  ...base,

      // When a merge request is first created, any assignees
      // in it are interpreted as new review requests.
      if (action === "open" || action === "reopen") {
        const { assignees = [] } = event;
        return assignees;
      }

      // Gitlab API provides any merge request update diff
      // as part of their response. We can check the presence of
      // the `assignees` attribute within those changes to verify

      // the difference in order to extract the new reviewers.
      const previousAssignees = new Set(reviewers.previous.map((a) => a.username));
      const newAssignees = reviewers.current.filter((a) => !previousAssignees.has(a.username));

    async emitEvent(event) {

      // but such event can be deduced from the payload of "merge request" events.

Trigger Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.
LabelPropTypeDescription
GitLabgitlabappThis component uses the GitLab app.
N/Adb$.service.dbThis component uses $.service.db to maintain state between executions.
N/Ahttp$.interface.httpThis component uses $.interface.http to generate a unique URL when the component is first instantiated. Each request to the URL will trigger the run() method of the component.
Project IDprojectIdintegerSelect a value from the drop down menu.

Trigger Authentication

GitLab uses OAuth authentication. When you connect your GitLab account, Pipedream will open a popup window where you can sign into GitLab and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any GitLab API.

Pipedream requests the following authorization scopes when you connect your account:

apiread_userread_repositorywrite_repositoryread_registrysudoopenidprofileemail

About GitLab

GitLab is the most comprehensive AI-powered DevSecOps Platform.

Action

Description:Write custom Node.js code and use any of the 400k+ npm packages available. Refer to the [Pipedream Node docs](https://pipedream.com/docs/code/nodejs) to learn more.
Version:0.0.2
Key:node-run-node-code

Node Overview

Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores.

This includes installing NPM packages, within your code without having to manage a package.json file or running npm install.

Below is an example of installing the axios package in a Pipedream Node.js code step. Pipedream imports the axios package, performs the API request, and shares the response with subsequent workflow steps:

Action Code

import node from "../../node.app.mjs";

export default {
  name: "Run Node Code",
  version: "0.0.2",
  key: "node-run-node-code",
  description: "Write custom Node.js code and use any of the 400k+ npm packages available. Refer to the [Pipedream Node docs](https://pipedream.com/docs/code/nodejs) to learn more.",
  props: {
    node,
  },
  type: "action",
  methods: {},
  async run({
    steps, $,
  }) {
    // Return data to use it in future steps
    return steps.trigger.event;
  },
};

Action Configuration

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI.

LabelPropTypeDescription
NodenodeappThis component uses the Node app.

Action Authentication

The Node API does not require authentication.

About Node

Anything you can do with Node.js, you can do in a Pipedream workflow. This includes using most of npm's 400,000+ packages.
