Example of how to extend Tiled with a custom route

1. Clone this gist and enter the directory.

2. Install Tiled and and, optionally, a HTTP client to test with.

   pip install tiled[all] httpie
   

danielballan

Tasks

1. Run python middlware.py.
2. Using HTTPie, request data: http :8000/data. This should return the list of numbers from the server.
3. Add a simple middleware that just uses print to print a message in the server logs before and after a request is seen.
4. Add a second middleware that also prints.

Question: Do the middlewares get run in the order that they are added in middlware.py or in the reverse order?

Experimental Databroker Sandbox

1. Install podman. https://podman.io/getting-started/installation

2. Install podman-compose:

   pip install podman-compose

3. Clone or copy docker-compose.yml and config.yml from this gist into a directory.

conda activate sandbox
pip install --pre tiled[all] databroker[all] ipython

Note for Mac: Mac uses zsh by default and it requires single quotes like 'databroker[all]'. On the other hand, Windows requires that you not have quotes.

mkdir sandbox
cd sandbox/

Databroker Migration Guide

What?

This is a draft of a guide for migrating from Databroker v1.x to Databroker v2.x (currently in prerelease). The data storage does not change; only the way it is accessed changes. It is possible to run Databroker v1.x and 2.x against the same MongoDB concurrently. Databroker 1.x was effectively a plugin to Intake. Databroker 2.x refactors Databroker as a plugin to Tiled, and drops any depenedency on Intake.
