Seam API Blueprint

Build tools for the Seam API using this blueprint.

Description

A blueprint is a simplified description of an API schema that is optimized for code and documentation generation.

The blueprint schema assumes the API follows Seam API design guidelines, and will evolve with those guidelines and any SDK, documentation, or product quality requirements.

The blueprint defines the following core concepts:

Endpoint: a path that accepts an HTTP request and returns a response.
Route: the direct parent path of a collection of one or more endpoints.
Subroute: a route that is nested under another route.
Namespace: the direct parent path of a collection routes only: there are no endpoints under this path.
Resource: every endpoint that returns non-empty data returns a resource or a collection of resources.

Motivation

The scope of the OpenAPI Specification covers arbitrarily complicated APIs, while the Seam API follows very predictable and simplified API design patterns.

For this reason, Seam has encountered several challenges working directly with the OpenAPI Specification:

Existing tools built on the OpenAPI Specification cannot meet Seam's requirements or require non-trivial extensions.
Extending the OpenAPI Specification with non-standard properties to support Seam's SDK and documentation requirements is not directly compatible with existing tools.
Seam's requirements and scope are overall simpler than the broad use-cases existing tools based on the OpenAPI Specification are trying to solve.
All existing Seam tooling must first expend duplicated effort parsing and flattening the OpenAPI Specification into a form more natural to the Seam API.
This creates a high barrier of entry for working with the Seam API specification as one must first deeply understand how to parse the OpenAPI Specification for any practical application.

The blueprint addresses these concerns:

The blueprint module centralizes on a source of truth for parsing the OpenAPI Specification into something usable.
The blueprint schema matches naturally to the Seam API design and is immediately usable for practical application.
The blueprint is not limited by the OpenAPI Specification or constrained by the wide scope of supporting any API. It is optimized for Seam's requirements and can evolve faster to meet Seam's specific concerns and integrate directly with other Seam integrated tooling.

Installation

Add this as a dependency to your project using npm with

$ npm install --save-dev @seamapi/blueprint

Usage

import { createBlueprint, TypesModuleSchema } from '@seamapi/blueprint'
import * as types from '@seamapi/types/connect'

const typesModule = TypesModuleSchema.parse(types)
const blueprint = await createBlueprint(typesModule)
console.log(JSON.stringify(blueprint)

Development and Testing

Quickstart

$ git clone https://github.com/seamapi/blueprint.git
$ cd blueprint
$ nvm install
$ npm install
$ npm run test:watch

Primary development tasks are defined under scripts in package.json and available via npm run. View them with

$ npm run

Source code

The source code is hosted on GitHub. Clone the project with

$ git clone git@github.com:seamapi/blueprint.git

Requirements

You will need Node.js with npm and a Node.js debugging client.

Be sure that all commands run under the correct Node version, e.g., if using nvm, install the correct version with

$ nvm install

Set the active version for each shell session with

$ nvm use

Install the development dependencies with

$ npm install

Publishing

Automatic

New versions are released automatically with semantic-release as long as commits follow the Angular Commit Message Conventions.

Manual

Publish a new version by triggering a version workflow_dispatch on GitHub Actions. The version input will be passed as the first argument to npm-version.

This may be done on the web or using the GitHub CLI with

$ gh workflow run version.yml --raw-field version=<version>

GitHub Actions

GitHub Actions should already be configured: this section is for reference only.

The following repository secrets must be set on GitHub Actions:

NPM_TOKEN: npm token for installing and publishing packages.
GH_TOKEN: A personal access token for the bot user with packages:write and contents:write permission.
GIT_USER_NAME: The GitHub bot user's real name.
GIT_USER_EMAIL: The GitHub bot user's email.
GPG_PRIVATE_KEY: The GitHub bot user's GPG private key.
GPG_PASSPHRASE: The GitHub bot user's GPG passphrase.

Contributing

If using squash merge, edit and ensure the commit message follows the Angular Commit Message Conventions specification. Otherwise, each individual commit must follow the Angular Commit Message Conventions specification.

Create your feature branch (git checkout -b my-new-feature).
Make changes.
Commit your changes (git commit -am 'Add some feature').
Push to the branch (git push origin my-new-feature).
Create a new draft pull request.
Ensure all checks pass.
Mark your pull request ready for review.
Wait for the required approval from the code owners.
Merge when ready.
