QUESTION
I want to call an action in React on a click. I would like the action to set an object in the store to null
.
Here is my component where the clicking will occur. I want the state to be null when the user clicks to leave the page.
This was my attempt. During which I learned you cannot import and call an action nullPhoto
. If I import nullPhoto
with connect
the object is null
all the time.

ANSWER
Answered 2020-May-30 at 07:01There only two files missing from the Tutorials
folder: step-by-step-guide-how-to-buy-agoras.md
and step-by-step-guide-how-to-store-agoras.md
.
I think that the issue is with the formatting of the frontmatter in these files, not with gatsby-source-git
.
As you can see, hat sets them apart from the other files is that they both have colon inside a value:
title: Agoras: How to Store
description: Agoras: How to Buy
You need to add quotes around those:
title: "Agoras: How to Store"
description: "Agoras: How to Buy"
Your query probably failed at parsing these, hence the files didn't appear. Let me know if this fixes your issue!

QUESTION
In React I want to click on one element and have the page scroll to another element.
I have seen this question answered on Stack Overflow but I don't know how to implement it inside a large component like the one I am working with.
The operative pieces are buried in the component below, but they are as follows.
Function that should scroll to the element...
const scrollToRef = (ref) => window.scrollTo(0, this.myRef.current)
Creation of Ref in the constructor...
this.myRef = React.createRef()
The element I want to click on that will scroll to the element desired...
The element I wish to scroll to...
If I change...
const scrollToRef = (ref) => window.scrollTo(0, this.myRef.current)
to
const scrollToRef = (ref) => window.scrollTo(0, 1400)
I get where I want, but of course this doesn't know what element I'm scrolling to and will not work for mobile.

This is my first time dealing with Gatsby and React, so I might be using the wrong approach on this matter. Anyway, this is what is going on.
From the gatsby-starter-hello-world, I'm building this site that will be composed of a front page with a Hero on the top, holding the intro information. Right bellow, I'm intending to insert some content (I'm not sure about what yet), with this

...ANSWER
Answered 2019-Sep-01 at 11:26You did not provide any error context or stack trace, so I will need to guess: "@babel/react"
preset is probably omitted during the build, so JSX hasn't been transpiled to valid JavaScript syntax.
Reason is: You included babel config twice - once in base.js
config under babel-loader options
, once in .babelrc
. In this case options
takes precedence and .babelrc
is omitted.
I assume here, that .babelrc
is the "complete" config, so remove options
entry and update your Webpack module config:
