octokit-plugin-create-pull-request

Octokit plugin to create a pull request with multiple file changes

Features

• Retrieves the repository’s default branch unless base branch is set
• Makes multiple file changes using a single commit
• Creates a fork if the authenticated user does not have write access to the repository
• See Todos for more cool feature ideas! Pull requests welcome!

Usage

<script type="module">
  import { Octokit } from "https://cdn.pika.dev/@octokit/core";
  import { createPullRequest } from "https://cdn.pika.dev/octokit-plugin-create-pull-request";
</script>

const { Octokit } = require("@octokit/core");
const { createPullRequest } = require("octokit-plugin-create-pull-request");

const MyOctokit = Octokit.plugin(createPullRequest);

const TOKEN = "secret123"; // create token at https://github.com/settings/tokens/new?scopes=repo
const octokit = new MyOctokit({
  auth: TOKEN,
});

// Returns a normal Octokit PR response
// See https://octokit.github.io/rest.js/#octokit-routes-pulls-create
octokit
  .createPullRequest({
    owner: "user-or-org-login",
    repo: "repo-name",
    title: "pull request title",
    body: "pull request description",
    base: "main" /* optional: defaults to default branch */,
    head: "pull-request-branch-name",
    changes: [
      {
        /* optional: if `files` is not passed, an empty commit is created instead */
        files: {
          "path/to/file1.txt": "Content for file1",
          "path/to/file2.png": {
            content: "_base64_encoded_content_",
            encoding: "base64",
          },
          // deletes file if it exists,
          "path/to/file3.txt": null,
          // updates file based on current content
          "path/to/file4.txt": ({ exists, encoding, content }) => {
            // do not create the file if it does not exist
            if (!exists) return null;

            return Buffer.from(content, encoding)
              .toString("utf-8")
              .toUpperCase();
          },
        },
        commit:
          "creating file1.txt, file2.png, deleting file3.txt, updating file4.txt (if it exists)",
      },
    ],
  })
  .then((pr) => console.log(pr.data.number));

By default, a pull request is created, even if no files have been changed. To prevent an empty pull request, set options.createWhenEmpty to false. If no pull request has been created, octokit.createPullRequest() resolves with null.

By default, commits are always created, even if no files have been updated. To prevent empty commits, set options.changes[].emptyCommit to false. To set a custom commit message for empty commits, set emptyCommit to a string.

For using this plugin with another plugin, you can import the composeCreatePullRequest function, which accepts an octokit instance as first argument, and the same options as octokit.createPullRequest as second argument.

import { Octokit } from "@octokit/core";
import { composeCreatePullRequest } from "octokit-plugin-create-pull-request";

export function myPlugin(octokit) {
  return {
    async myFunction(options) {
      // custom code here

      const response = await composeCreatePullRequest(octokit, options);

      // more custom code here

      return response;
    },
  };
}
