Why does PathPrefixStrip work when PathPrefix won't?

由 社会主义新天地 提交于 2019-12-07 11:48:08
问题 I have a GatsbyJS static site built with --prefix-paths . The pathPrefix is set to /environment/test in gatsby-config.js . It is deployed to a docker swarm running Traefik. Adding the following label to the service makes everything run ok: traefik.frontend.rule=PathPrefixStrip:/environment/test I can then browse to /environment/test and click around in my GatsbyJs site. However I find it strange since the backend is build with the path prefix. Adding the following label does not work: traefik

Gatsby.js: Filter GraphQL query by nested object property

由 梦想的初衷 提交于 2019-12-07 05:35:51
问题 I'm working on a news site which will have articles, each with one or multiple respective authors. If you click on an author's name, it will take you to a page displaying their information and a list of articles they have contributed to. So each article has an authors property, which in turn is an array of author objects with properties: full name, slug ( lowercase version of full name with spaces replaced by dashes ), etc. Is it possible to filter the articles by a particular author's slug

Gatsby.js: Navigating with URL Parameters and the Browser Back / Forward Buttons

由 给你一囗甜甜゛ 提交于 2019-12-07 02:21:35
问题 I have an Articles component which displays a list of posts. The list is paginated so that a maximum of 10 posts can display per page. There is a "Next Page" button that when clicked will update the component state and the corresponding url parameter like so: page 1: /news page 2: /news?page=2 page 3: /news?page=3 ...and so on. The way the constructor() and render() methods are set up, it will read this URL parameter and display the correct posts if the user navigates directly to /news?page=3

由 假如想象 提交于 2019-12-06 14:37:22
I need to pull in the contents of a program source file for display in a page generated by Gatsby.

Gatsby-js client side javascript inline in blog post

由 南楼画角 提交于 2019-12-06 12:39:40
I am trying to setup a Blog using Gatsby-JS. I have some posts in markdown that contain inline javascript. As an example: <script>window.alert("hello");</script> I test the site using the command "Gatsby serve" When I browse to my post via the index of the blog. The script is not executed.

I cannot get the script to execute by F5 or by navigating via the index. Only when I press ctrl+F5 the script is

由 淺唱寂寞╮ 提交于 2019-12-06 06:28:58
问题 Please note that I'm still learning to use Gatsby & React. I have been trying to figure out how to properly use the Google Tag Manager Plugin for Gatsbyjs to insert tracking codes into my app. The official documentation of the plugin does not provide a lot of insights and examples, so I'm not sure if I understand it completely. What I want to do is to insert two GTM tracking codes into my app, one in <head> and one in <body> . With the static site approach, I could just copy and paste the GTM
