github-project

JavaScript SDK for GitHub's new Projects

Features

Use GitHub Projects (beta) as a database of issues and pull requests with custom fields.
Simple interaction with item fields and content (draft/issue/pull request) properties.
Look up items by issue/pull request node IDs or number and repository name.
100% test coverage and type definitions.

Usage

Browsers	Load `github-project` directly from cdn.skypack.dev <script type="module"> import GitHubProject from "https://cdn.skypack.dev/github-project"; </script>
Node	Install with `npm install github-project` import GitHubProject from "github-project";

A project always belongs to a user or organization account and has a number. For authentication you can pass a personal access token with project and write:org scopes. For read-only access the read:org and read:project scopes are sufficient.

fields is map of internal field names to the project's column labels. The comparison is case-insensitive. "Priority" will match both a field with the label "Priority" and one with the label "priority". An error will be thrown if a project field isn't found, unless the field is set to optional: true.

const options = {
  owner: "my-org",
  number: 1,
  token: "ghp_s3cR3t",
  fields: {
    priority: "Priority",
    dueAt: "Due",
    lastUpdate: { name: "Last Update", optional: true },
  },
};

const project = new GitHubProject(options);

// Alternatively, you can call the factory method to get a project instance
// const project = await GithubProject.getInstance(options)

// get project data
const projectData = await project.get();
console.log(projectData.description);

// log out all items
const items = await project.items.list();
for (const item of items) {
  // every item has a `.fields` property for the custom fields
  // and an `.content` property which is set unless the item is a draft
  console.log(
    "%s is due on %s (Priority: %d, Assignees: %j)",
    item.fields.title,
    item.fields.dueAt,
    item.fields.priority,
    item.type === "REDACTED"
      ? "_redacted_"
      : item.content.assignees.map(({ login }) => login).join(","),
  );
}

// add a new item using an existing issue
// You would usually retrieve the issue node ID from an event payload, such as `event.issue.node_id`
const newItem = await project.items.add(issue.node_id, { priority: 1 });

// retrieve a single item using the issue node ID (passing item node ID as string works, too)
const item = await project.items.getByContentId(issue.node_id);

// item is undefined when not found
if (item) {
  // update an item
  const updatedItem = await project.items.update(item.id, { priority: 2 });

  // remove item
  await project.items.remove(item.id);
}

API

Constructor

const project = new GitHubProject(options);

Factory method

The factory method is useful when you want immediate access to the project's data, for example to get the project's title. Will throw an error if the project doesn't exist.

const project = GitHubProject.getInstance(options);

name	type	description
`options.owner`	`string`	Required. The account name of the GitHub organization.
`options.number`	`Number`	Required. Project number as you see it in the URL of the project.
`options.token`	`String`	Required unless `options.octokit` is set. When set to a personal access token or an OAuth token, the `read:org` scope is required for read-only access, and the `write:org` scope is required for read-write access. When set to an installation access token, the `organization_projects:read` permission is required for read-only access, and the `organization_projects:write` permission is required for read-write access.
`options.octokit`	`Octokit`	Required unless `options.token` is set. You can pass an `@octokit/core` instance, or an instance of any `Octokit` class that is built upon it, such as `octokit`.
`options.fields`	`Object`	Required. A map of internal names for fields to the column names or field option objects. The `title` key will always be set to `"Title"` and `status` to `"Status"` to account for the built-in fields. The other built-in columns `Assignees`, `Labels`, `Linked Pull Requests`, `Milestone`, `Repository`, and `Reviewers` cannot be set through the project and are not considered fields. You have to set them on the issue or pull request, and you can access them by `item.content.assignees`, `item.content.labels` etc (for both issues and pull requests). A field option object must include a `name` key and can include an `optional` key. When `optional` is `false` or omitted, an error will be thrown if the field is not found in the project. When `optional` is `true`, the error will be replaced by an `info` log via the Octokit Logger. Optional fields that don't exist in the project are not set on items returned by the `project.items.*` methods.
`options.matchFieldName`	`Function`	Customize how field names are matched with the values provided in `options.fields`. The function accepts two arguments: `projectFieldName` `userFieldName` Both are strings. Both arguments are lower-cased and trimmed before passed to the function. The function must return `true` or `false`. Defaults to function (projectFieldName, userFieldName) { return projectFieldName === userFieldName }
`options.matchFieldOptionValue`	`Function`	Customize how field options are matched with the field values set in `project.items.add()`, `project.items.addDraft()`, or `project.items.update*()` methods. The function accepts two arguments: `fieldOptionValue` `userValue` Both are strings. Both arguments are trimmed before passed to the function. The function must return `true` or `false`. Defaults to function (fieldOptionValue, userValue) { return fieldOptionValue === userValue }
`options.truncate`	`Function`	Text field values cannot exceed 1024 characters. By default, the `options.truncate` just returns text as is. We recommend to use an establish truncate function such as loadsh's `_.truncate()`, as byte size is not the same as text length.

Errors

Expected errors are thrown using custom Error classes. You can check for any error thrown by github-project or for specific errors.

Custom errors are designed in a way that error.message does not leak any user content. All errors do provide a .toHumanMessage() method if you want to provide a more helpful error message which includes both project data as well ase user-provided data.

import Project, { GitHubProjectError } from "github-project";

try {
  await myScript(new Project(options));
} catch (error) {
  if (error instanceof GitHubProjectError) {
    myLogger.error(
      {
        // .code and .details are always set on GitHubProjectError instances
        code: error.code,
        details: error.details,
        // log out helpful human-readable error message, but beware that it likely contains user content
      },
      error.toHumanMessage(),
    );
  } else {
    // handle any other error
    myLogger.error({ error }, `An unexpected error occurred`);
  }

  throw error;
}

`GitHubProjectNotFoundError`

Thrown when a project cannot be found based on the owner and number passed to the Project constructor. The error is also thrown if the project exists but cannot be found based on authentication.

import Project, { GitHubProjectNotFoundError } from "github-project";

try {
  await myScript(new Project(options));
} catch (error) {
  if (error instanceof GitHubProjectNotFoundError) {
    analytics.track("GitHubProjectNotFoundError", {
      owner: error.details.owner,
      number: error.details.number,
    });

    myLogger.error(
      {
        code: error.code,
        details: error.details,
      },
      error.toHumanMessage(),
    );
  }

  throw error;
}

name	type	description
`name`	`constant`	`GitHubProjectNotFoundError`
`message`	`constant`	Project cannot be found
`details`	`object`	Object with error details
`details.owner`	`string`	Login of owner of the project
`details.number`	`number`	Number of the project
