Superset pgadmin and psql connections
Connection to superset docker container with pgadmin GUI tool and psql in docker container. Superset SQLLab is not the same SQL interface as provided by psql or pgadmin. The additional capabilities and better runtime including more meaningful exception messages save time. JOINS not well supported in the superset interface. After many wasted hours I now use native db tools for POCs to show data format and query performance with a flask app before porting to SS.

superset install db not working

Temp video, did not wait for docker build to finish and db init didnt download the sample data. Redo video when time. Key point was to kill the db before docker compose up. Always forget and it costs me 20m to redebug the process

Add button to add data to echart hook. Helps sort out useState variables and verify useEffect works in rerender when data is added. Simplest dumbest example to reduce complexity from superset source code.

Difference between counter with console.log and rendered display. Console.log lags one behind display state. Use debugger to show why and where the closure is.

Stop grabbing the shark and trying to swim next to it like your favorite Disney movie
This is the stale value problem mentioned in Josh's class: courses.joshwcomeau.com/joy-of-react/03-hooks/05.08-stale-values. To fix this add. // useEffect(()=>{ // console.log("useEffect count:",count) // },[count]) But the point of the video is to demo a debug tool for finding closures.
These videos use apache@4.2.1 not apache echart 5. The 5 version is completely different.
2 common errors when following the apache superset plugin instructions verbatim 1) import the newly created library with a destructure above the last plugin and make sure the spaces and formatting match exactly to prevent lint errors new SupersetPluginChartEhartLine().configure({ key: 'echart line' }), ...experimentalPlugins, 2) Uncaught runtime errors: ERROR section is undefined This error can be found from the github issue post here: github.com/apache/superset/discussions/27412 Remove from src/plugins/controlPanel.ts the sections.legacyRegularTime, line
[HPM] Error occurred while proxying request localhost:9000/ to localhost:8088/ [ECONNREFUSED] (nodejs.org/api/errors.html#errors_common_system_errors) means the docker service isnt up. they all have to be running except superset init
not worth redoing the db init and sample data install takes many minutes. Let the docker compose -f docker-compose-image-tag.yml up run for 20m until you see DEBUG:superset-stats-logger. Make sure to delete the docker volumes if corrupted or want to start over. The db data is stored on the docker db volumes
Make sure strict mode is off or you will get 2x
