Subfork Python API

Subfork Python API

Subfork is the easiest way to build and deploy static sites and micro web apps. This package provides the Subfork Python API and command line interface.

• Docs: https://docs.subfork.com
• GitHub: https://github.com/subforkdev/subfork
• PyPI: https://pypi.org/project/subfork

Installation

The easiest way to install:

$ pip install subfork

Source code:

$ git clone https://github.com/subforkdev/subfork

Requires Python 3.6+.

Setup

In order to authenticate with the Subfork API, you will first need to create a site and API access keys for your site at subfork.com.

To use environment variables, set the following:

$ export SUBFORK_ACCESS_KEY=<access key>
$ export SUBFORK_SECRET_KEY=<secret key>

Or create a subfork.yml config file at the root of your project or set $SUBFORK_CONFIG_FILE to the path to subfork.yml:

$ export SUBFORK_CONFIG_FILE=/path/to/subfork.yml

Quick Start

To use the Subfork Python API you must first complete the configuration steps below. Then instantiate a client using the site domain and access keys:

import subfork

client = subfork.get_client()
site = client.site()

Getting pages:

# get all the pages
pages = site.pages()

# or a specific page
page = site.get_page("index.html")

Getting data:

# get all of the 'bookings' for 'Sally'
params = [["guestid", "=", "Sally"]]
results = site.get_data("bookings").find(params)

Updating data:

# update the 'total' value for a booking
data = site.get_data("bookings").find_one(params)
data["total"] = 600.00
results = site.get_data("bookings").update(data["id"], data)

Basic Commands

To create a subfork.yml config file from existing html templates and static files:

$ subfork create -t <templates folder> -s <static folder>

where the templates folder is the folder containing all of the html files, and the static folder is the folder containing all of the static files (.jpg, .js, .css, etc). Be sure to update the values in the new subfork.yml if necessary.

To test a site locally using the dev server:

$ subfork run

To deploy and release a site:

$ subfork deploy -c "initial deployment" --release

To process queued tasks using workers defined in the config file:

$ subfork worker

Workers

Task workers are decentralized Python functions that poll task queues for new jobs. As new jobs are added to the queue, task workers pull them off and pass data to the specified Python function.

See the subfork.worker.test function for an example of a simple worker that takes jobs from the test queue and returns a string.

To run a worker that pulls jobs from the test queue and runs the test function:

$ subfork worker --queue test --func subfork.worker.test

Workers will automatically retry failed jobs.

Getting task results:

queue = site.get_queue("test")
task = queue.get_task(taskid)
results = task.get_results()

Creating new tasks:

task = queue.create_task({"t": 1})

Tasks and task data can be viewed on the tasks page of the subfork dashboard.

Config File

The subfork.yml config file contains required auth info, page templates, routes (or endpoints), static files and task worker definitions.

For example, this config file contains two endpoints and a worker:

# enter site domain (e.g. mysite.fork.io)
domain: ${SUBFORK_DOMAIN}

# enter site credentials here
access_key: ${SUBFORK_ACCESS_KEY}
secret_key: ${SUBFORK_SECRET_KEY}

# path to templates and static files (optional)
template_folder: templates
static_folder: static

# page template definitions
templates:
  index:
    route: /
    file: index.html
  user:
    route: /user/<username>
    file: user.html

# task worker definitions (optional)
workers:
  test:
    queue: test
    function: subfork.worker.test
