fetch

问题 So I'm designing a function that inserts a row into the MySQL database. The table has a Primary key with Auto-Increment enabled. So I don't insert the value of this column.

问题 Trying to bring up a highchart using react. I am having multiple fetch api calls(for illustration, I have added only 2) whose data I will be using to render something in the UI.

When I am calling these API's, I am getting the data but unable to set it to "series" property of highcharts for rendering, as a result nothing is getting rendered. Structure

问题 I am using cross fetch in a react app with redux. In my reducer I save some data to the database using cross fetch's post method. My call returns a response with some data I need to assign to state after saving. I'm having trouble parsing the data though. Below is what the response looks like.
