labguru-api-client 0.1.3

Python api client for accessing the Labguru Electronic Lab Notebook.

labguru-api-client

Python api client for accessing the Labguru Electronic Lab Notebook.

This package contains two main groups of code:

1. Generated code from the OpenAPI spec for the Labguru API, using openapi-python-client. This code is in the labguru_api_client directory.
2. Wrapper functions around the generated code to make it easier to use. This part is still in development.

Installing

You can install this package using pip:

pip install labguru-api-client

Usage (wrapper functions)

Wrapper functions are under active development and are expected to change. For now, a few experiment-related fucntions have been defined.

from labguru_wrapper.labguru_api import LabguruAPI

# define env vars in ~/.labguru.env
# LABGURU_API_KEY is required
# LABGURU_BASE_URL is optional
labguru = LabguruAPI()

exp1_1 = labguru.get_experiment(1)
# returned object will be a dict/json representation of the experiment
print(exp1_1["title"])

exp1_updated = labguru.update_experiment(1, {"title": "My new title"})
assert labguru.get_experiment(1)["title"] == "My new title"

Usage (generated code)

Create a client and make an example request to get an experiment by id. Your Labguru API key should be stored in an environment variable called LABGURU_API_KEY. Extracing information from the response can be done by parsing the response.content attribute. The Labguru openAPI spec did not include a response model for their endpoints, so response.parsed will be None.

import json
from labguru_api_client import Client
from labguru_api_client.api.experiments import get_api_v1_experiments_id

client = Client(base_url="https://my.labguru.com/")
exp_1 = get_api_v1_experiments_id.sync_detailed(client=client, token=os.getenv("LABGURU_API_KEY"), id=1)
if exp_1.status_code == 200:
    print(json.loads(exp_1.content)["title"])

To update or create an experiment, use the generated models to create a body for the request.

import json
from labguru_api_client import Client
from labguru_api_client.api.experiments import put_api_v1_experiments_id
from labguru_api_client.models import UpdateExperimentItem, UpdateExperiment

updated_experiment_item = UpdateExperimentItem.from_dict({
    "title": "My new title"
})
updated_experiment = UpdateExperiment(token=os.getenv("LABGURU_API_KEY"), item=updated_experiment_item)

exp_1_put = put_api_v1_experiments_id.sync_detailed(client=client, id=1, body=updated_experiment)
exp_1_updated = get_api_v1_experiments_id.sync_detailed(client=client, token=os.getenv("LABGURU_API_KEY"), id=1)
if exp_1_put.status_code == 200 and exp_1_updated.status_code == 200:
    assert json.loads(exp_1_updated.content)["title"] == "My new title"

Things to know:

1. Every path/method combo becomes a Python module with four functions:

   1. sync: Blocking request that returns parsed data (if successful) or None
   2. sync_detailed: Blocking request that always returns a Request, optionally with parsed set if the request was successful.
   3. asyncio: Like sync but async instead of blocking
   4. asyncio_detailed: Like sync_detailed but async instead of blocking

2. All path/query params, and bodies become method arguments.

3. If your endpoint had any tags on it, the first tag will be used as a module name for the function (my_tag above)

4. Any endpoint which did not have a tag will be in labguru_api_client.api.default

Advanced customizations

There are more settings on the generated Client class which let you control more runtime behavior, check out the docstring on that class for more info. You can also customize the underlying httpx.Client or httpx.AsyncClient (depending on your use-case):

from labguru_api_client import Client

def log_request(request):
    print(f"Request event hook: {request.method} {request.url} - Waiting for response")

def log_response(response):
    request = response.request
    print(f"Response event hook: {request.method} {request.url} - Status {response.status_code}")

client = Client(
    base_url="https://my.labguru.com",
    httpx_args={"event_hooks": {"request": [log_request], "response": [log_response]}},
)

# Or get the underlying httpx client to modify directly with client.get_httpx_client() or client.get_async_httpx_client()

You can even set the httpx client directly, but beware that this will override any existing settings (e.g., base_url):

import httpx
from labguru_api_client import Client

client = Client(
    base_url="https://my.labguru.com",
)
# Note that base_url needs to be re-set, as would any shared cookies, headers, etc.
client.set_httpx_client(httpx.Client(base_url="https://my.labguru.com", proxies="http://localhost:8030"))
