pip install .

🔧 Usage

General function description

• add_<type>(): Create a new element.
• delete_<type>(): Delete an element by ID.
• get_<type>(): Get an element by ID.
• get_all_<type>(): Get all elements of a kind.

For details, consult the implementation, joplin documentation or create an issue.

💡 Example snippets

Start joplin and get your API token. Click to expand the examples.

Get all notes

from joppy.api import Api

# Create a new Api instance.
api = Api(token=YOUR_TOKEN)

# Get all notes. Note that this method calls get_notes() multiple times to assemble the unpaginated result.
notes = api.get_all_notes()

Add a tag to a note

from joppy.api import Api

# Create a new Api instance.

api = Api(token=YOUR_TOKEN)

# Add a notebook.

notebook_id = api.add_notebook(title="My first notebook")

# Add a note in the previously created notebook.

note_id = api.add_note(title="My first note", body="With some content", parent_id=notebook_id)

# Add a tag, that is not yet attached to a note.

tag_id = api.add_tag(title="introduction")

# Link the tag to the note.

api.add_tag_to_note(tag_id=tag_id, note_id=note_id)

Add a resource to a note

from joppy.api import Api
from joppy import tools

# Create a new Api instance.
api = Api(token=YOUR_TOKEN)

# Add a notebook.
notebook_id = api.add_notebook(title="My first notebook")

# Option 1: Add a note with an image data URL. This works only for images.
image_data = tools.encode_base64("path/to/image.png")
api.add_note(
    title="My first note",
    image_data_url=f"data:image/png;base64,{image_data}",
)

# Option 2: Create note and resource separately. Link them later. This works for arbitrary attachments.
note_id = api.add_note(title="My second note")
resource_id = api.add_resource(filename="path/to/image.png", title="My first resource")
api.add_resource_to_note(resource_id=resource_id, note_id=note_id)

Bulk remove tags

Inspired by https://discourse.joplinapp.org/t/bulk-tag-delete-python-script/5497/1.

import re

from joppy.api import Api

# Create a new Api instance.
api = Api(token=YOUR_TOKEN)

# Iterate through all tags.
for tag in api.get_all_tags():

    # Delete all tags that match the regex. I. e. start with "!".
    if re.search("^!", tag.title) is not None:
        api.delete_tag(tag.id)

Remove spaces from tags

Inspired by https://www.reddit.com/r/joplinapp/comments/pozric/batch_remove_spaces_from_all_tags/.

import re

from joppy.api import Api

# Create a new Api instance.
api = Api(token=YOUR_TOKEN)

# Define the conversion function.
def to_camel_case(name: str) -> str:
    name = re.sub(r"(_|-)+", " ", name).title().replace(" ", "")
    return "".join([name[0].lower(), name[1:]])

# Iterate through all tags and apply the conversion.
for tag in api.get_all_tags():
    api.modify_tag(id_=tag.id, title=to_camel_case(tag.title))

Remove orphaned resources

Inspired by https://discourse.joplinapp.org/t/joplin-vacuum-a-python-script-to-remove-orphaned-resources/19742. Note: The note history is not considered. See: https://discourse.joplinapp.org/t/joplin-vacuum-a-python-script-to-remove-orphaned-resources/19742/13.

import re

from joppy.api import Api

# Create a new Api instance.
api = Api(token=YOUR_TOKEN)

# Getting the referenced resource directly doesn't work:
# https://github.com/laurent22/joplin/issues/4535
# So we have to find the referenced resources by regex.

# Iterate through all notes and find the referenced resources.
referenced_resources = set()
for note in api.get_all_notes(fields="id,body"):
    matches = re.findall(r"\[.*\]\(:.*\/([A-Za-z0-9]{32})\)", note.body)
    referenced_resources.update(matches)

assert len(referenced_resources) > 0, "sanity check"

for resource in api.get_all_resources():
    if resource.id not in referenced_resources:
        print("Deleting resource:", resource)
        api.delete_resource(resource.id)

📰 Example scripts

Before using joppy, you should check the Joplin plugins. They are probably more convenient. However, if you need a new feature or just want to code in python, you can use joppy. Below are example scripts to showcase how joppy can be used.

Script	Description
custom_export.py	Export resources next to notes, instead of a separate folder.
note_export.py	Export notes to any format supported by pandoc.
note_stats.py	Get some simple statistics about your notes, based on nltk.
note_tree_export.py	Joplin only supports PDF export of a single note. This script allows to export one, multiple or all notebooks to PDF or TXT.
visualize_note_locations.py	Visualize the locations of your notes.
https://github.com/marph91/joplin-ui-tests	System tests for the joplin desktop app. Based on selenium.
https://github.com/gri38/django-joplin_vieweb	Web viewer for joplin.
https://github.com/BeneKurz/Toodledo2Joplin	Import notes from https://www.toodledo.com to Joplin.

☀️ Tests

To run the tests, some additional system packages and python modules are needed. After installing them, just run:

python -m unittest

It's possible to configure the test run via some environment variables:

• SLOW_TESTS: Set this variable to run the slow tests. Default not set.
• API_TOKEN: Set this variable if there is already a joplin instance running. Don't use your default joplin profile! By default, a joplin instance is started inside xvfb. This takes some time, but works for CI.

❓ FAQ

Short summary about questions I had during the implementation.

• What is the purpose/usecase of "user_created_time"? Isn't "created_time" sufficient? → https://discourse.joplinapp.org/t/importing-notes-from-tiddlywiki-api-feature-request-for-timestamps/1952/7
• Why is the token in the query? → https://discourse.joplinapp.org/t/joplin-api-token-in-header-vs-query-parameters/12573/5
