HappyGAPI2

A Clojure library for calling Google APIs; gsheets, drive, bigquery, and so on.

This project is the successor to HappyGAPI (deprecated), the oauth2 and generation were moved to HappyAPI. The new artifact name io.github.timothypratley/happygapi2 was introduced to avoid breaking changes.

Rationale

HappyGAPI2 is a bunch of generated functions (as code, not macros) for calling GAPI, so that your editor can help you (autocomplete, help documentation, and arg checking).

Navigate to source
See all available resources and methods
Clear exception stack traces on failure
The function doc-strings contain a description, a link to online docs, and example inputs
Needs to be regenerated to discovery API updates

Usage

Add the dependency to the project file:

Require happygapi2.<<api>> in the code:

(ns my.ns
  (:require [happygapi2.sheets :as sheets]))

(sheets/spreadsheets-get "SPREADSHEET-ID")

Authorization

To create an app in the Google Console, follow Setting up OAuth 2.0. When setting up the app credentials, add http://localhost/redirect to the authorized redirect URIs, and add yourself as a test user.

There are two methods for obtaining a token:

User redirects, which prompt a user to authorize your app. Download the secret.json from the Google Console. Do not add this file to source control, keep it secured. This method is suitable if you want users to grant your app access to their data.
Service account private key (suitable for server to server). Create a Service account and download a service.json key file. Do not add this file to source control, keep it secured. This method is suitable for automated jobs.

The happy.oauth2-credentials namespace provides a convenient way to manage authorization. By default, it tries to read secret.json or service.json from disk in the current directory. You can pass in configuration map of the same shape instead. happy.oauth2-credentials stores tokens on disk. If you want to use HappyGAPI in a web app, you should instead store and fetch tokens from your database. This can be done by calling init! with a fetch and store function, or by creating your own implementation of auth!.

The happy.oauth2-capture-redirect namespace provides a listener to capture a code when the user is redirected to your site from the oauth2 provider. If you use it, you will need to include ring as a dependency. Web applications should instead define a route to capture the code.

The happy.oauth2 namespace provides generic functions to support oauth2 authorization so that you can assemble only the parts you need.
