I'm using Gatsby/Netlify CMS stack and have been trying to display markdown file contents on the main page. For example, I have a directory in src/pages/experience that displays all of the experience markdown files.
So using graphql, I have a query that actually works:
{
allMarkdownRemark(
limit: 3,
sort: { order: DESC, fields: [frontmatter___date] },
filter: { fileAbsolutePath: { regex: "/(experience)/" } }
) {
edges {
node {
id
frontmatter {
title
company_role
location
work_from
work_to
tags
}
excerpt
}
}
}
}
However, when running it on my component page it displays × TypeError: Cannot read property 'allMarkdownRemark' of undefined
However after entering this before return:
if (!data) { return null };
The error goes away but the entire section disappears. Here it is below:
const Experience = ({data}) => {
return (
<div id="experience" className="section accent">
<div className="w-container">
<div className="section-title-group">
<Link to="#experience"><h2 className="section-heading centered">Experience</h2></Link>
</div>
<div className="columns w-row">
{data.allMarkdownRemark.edges.map(({node}) => (
<div className="column-2 w-col w-col-4 w-col-stack" key={node.id}>
<div className="text-block"><strong>{node.frontmatter.title}</strong></div>
<div className="text-block-4">{node.frontmatter.company_role}</div>
<div className="text-block-4">{node.frontmatter.location}</div>
<div className="text-block-3">{node.frontmatter.work_from} – {node.frontmatter.work_to}</div>
<p className="paragraph">{node.frontmatter.excerpt}</p>
<div className="skill-div">{node.frontmatter.tags}</div>
</div>
))}
</div>
</div>
</div>
)}
export default Experience
In gatsby-config-js, I've added a gatsby-source-filesystem resolve separate from /src/posts to /src/pages where the experience directory is src/pages/experience.
Update: 2/7/2019 Here is the gatsby-config-js file:
module.exports = {
siteMetadata: {
title: `Howard Tibbs Portfolio`,
description: `This is a barebones template for my portfolio site`,
author: `Howard Tibbs III`,
createdAt: 2019
},
plugins: [
`gatsby-plugin-react-helmet`,
{
resolve: `gatsby-source-filesystem`,
options: {
name: `images`,
path: `${__dirname}/src/images`,
},
},
{
resolve: 'gatsby-transformer-remark',
options: {
plugins: [
{
resolve: 'gatsby-remark-images',
},
],
},
},
{
resolve: `gatsby-source-filesystem`,
options: {
name: `posts`,
path: `${__dirname}/src/posts`,
},
},
{
resolve: `gatsby-source-filesystem`,
options: {
name: `pages`,
path: `${__dirname}/src/pages`,
},
},
`gatsby-plugin-netlify-cms`,
`gatsby-plugin-sharp`,
{
resolve: `gatsby-plugin-manifest`,
options: {
name: `gatsby-starter-default`,
short_name: `starter`,
start_url: `/`,
background_color: `#663399`,
theme_color: `#663399`,
display: `minimal-ui`,
icon: `src/images/gatsby-icon.png`, // This path is relative to the root of the site.
},
},
`gatsby-transformer-sharp`
],
}
What I feel is that somewhere in gatsby-node-js, I did not create a instance to do something with that type query.
const path = require('path')
const { createFilePath } = require('gatsby-source-filesystem')
const PostTemplate = path.resolve('./src/templates/post-template.js')
const BlogTemplate = path.resolve('./src/templates/blog-template.js')
exports.onCreateNode = ({ node, getNode, actions }) => {
const { createNodeField } = actions
if (node.internal.type === 'MarkdownRemark') {
const slug = createFilePath({ node, getNode, basePath: 'posts' })
createNodeField({
node,
name: 'slug',
value: slug,
})
}
}
exports.createPages = async ({ graphql, actions }) => {
const { createPage } = actions
const result = await graphql(`
{
allMarkdownRemark (limit: 1000) {
edges {
node {
fields {
slug
}
}
}
}
}
`)
const posts = result.data.allMarkdownRemark.edges
posts.forEach(({ node: post }) => {
createPage({
path: `posts${post.fields.slug}`,
component: PostTemplate,
context: {
slug: post.fields.slug,
},
})
})
const postsPerPage = 2
const totalPages = Math.ceil(posts.length / postsPerPage)
Array.from({ length: totalPages }).forEach((_, index) => {
const currentPage = index + 1
const isFirstPage = index === 0
const isLastPage = currentPage === totalPages
createPage({
path: isFirstPage ? '/blog' : `/blog/${currentPage}`,
component: BlogTemplate,
context: {
limit: postsPerPage,
skip: index * postsPerPage,
isFirstPage,
isLastPage,
currentPage,
totalPages,
},
})
})
}
Wanted to know if anyone was able to get something similar to work? Greatly appreciate your help.
Update: 2/6/2019
So made some changes to my code from pageQuery to StaticQuery and unfortunately it still doesn't work but I believe it is going the right direction:
export default() => (
<div id="experience" className="section accent">
<div className="w-container">
<div className="section-title-group">
<Link to="#experience"><h2 className="section-heading centered">Experience</h2></Link>
</div>
<div className="columns w-row">
<StaticQuery
query={graphql`
query ExperienceQuery {
allMarkdownRemark(
limit: 2,
sort: { order: DESC, fields: [frontmatter___date]},
filter: {fileAbsolutePath: {regex: "/(experience)/"}}
) {
edges {
node {
id
frontmatter {
title
company_role
location
work_from
work_to
tags
}
excerpt
}
}
}
}
`}
render={data => (
<div className="column-2 w-col w-col-4 w-col-stack" key={data.allMarkdownRemark.id}>
<div className="text-block"><strong>{data.allMarkdownRemark.frontmatter.title}</strong></div>
<div className="text-block-4">{data.allMarkdownRemark.frontmatter.company_role}</div>
<div className="text-block-4">{data.allMarkdownRemark.frontmatter.location}</div>
<div className="text-block-3">{data.allMarkdownRemark.frontmatter.work_from} – {data.allMarkdownRemark.frontmatter.work_to}</div>
<p className="paragraph">{data.allMarkdownRemark.frontmatter.excerpt}</p>
<div className="skill-div">{data.allMarkdownRemark.frontmatter.tags}</div>
</div>
)}
/>
</div>
</div>
</div>
);
I get this error TypeError: Cannot read property 'title' of undefined
So what I'm trying to accomplish is this instance across this section. Of course this is a placeholder but I'm looking to replace that placeholder with the contents of each markdown. Experience snip
Update: 2/7/2019
So no changes today but wanted to post a few fields to get a better perspective of what I'm trying to do. This is the config.yml file from NetlifyCMS where it is displaying the collections. This is what I'm accomplishing (Note: the test repo is just to see the actual CMS, I will look to change):
backend:
name: test-repo
branch: master
media_folder: static/images
public_folder: /images
display_url: https://gatsby-netlify-cms-example.netlify.com/
# This line should *not* be indented
publish_mode: editorial_workflow
collections:
- name: "experience"
label: "Experience"
folder: "experience"
create: true
fields:
- { name: "title", label: "Company Title", widget: "string" }
- { name: "company_role", label: "Position Title", widget: "string" }
- { name: "location", label: "Location", widget: "string" }
- { name: "work_from", label: "From", widget: "date", format: "MMM YYYY" }
- { name: "work_to", label: "To", default: "Present", widget: "date", format: "MMM YYYY" }
- { name: "description", label: "Description", widget: "text" }
- { name: "tags", label: "Skills Tags", widget: "select", multiple: "true",
options: ["ReactJS", "NodeJS", "HTML", "CSS", "Sass", "PHP", "Typescript", "Joomla", "CMS Made Simple"] }
- name: "blog"
label: "Blog"
folder: "blog"
create: true
slug: "{{year}}-{{month}}-{{day}}_{{slug}}"
fields:
- { name: path, label: Path }
- { label: "Image", name: "image", widget: "image" }
- { name: title, label: Title }
- { label: "Publish Date", name: "date", widget: "datetime" }
- {label: "Category", name: "category", widget: "string"}
- { name: "body", label: "body", widget: markdown }
- { name: tags, label: Tags, widget: list }
- name: "projects"
label: "Projects"
folder: "projects"
create: true
fields:
- { name: date, label: Date, widget: date }
- {label: "Category", name: "category", widget: "string"}
- { name: title, label: Title }
- { label: "Image", name: "image", widget: "image" }
- { label: "Description", name: "description", widget: "text" }
- { name: body, label: "Details", widget: markdown }
- { name: tags, label: Tags, widget: list}
- name: "about"
label: "About"
folder: "src/pages/about"
create: false
slug: "{{slug}}"
fields:
- {
label: "Content Type",
name: "contentType",
widget: "hidden",
default: "about",
}
- { label: "Path", name: "path", widget: "hidden", default: "/about" }
- { label: "Title", name: "title", widget: "string" }
- { label: "Body", name: "body", widget: "markdown" }
And for an example of a markdown page, this would be the format to look for in the Experience section, because as you see in the picture it displays across the container:
---
title: Test Company
company_role: Test Role
location: Anytown, USA
work_from: January, 2020
work_to: January, 2020
tags: Test, Customer Service
---
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
Update: 2/8/2019
I do have some updates with the code provided below but before I get into it, here are a few images of what I'm looking to accomplish. These are placeholders that I'm looking to replace for real data. This is for each section:
I've ran the code that was provided by @staypuftman in the answer below and came up with this error:
Your site's "gatsby-node.js" created a page with a component that doesn't exist.
I've added the code in addition to what was already there and it processed that error. This is what I originally thought would happen and the reason I wanted to use StaticQuery independently. This was actually the main issue I had with the documentation and the starter repos, no one really has created multiple variables in node.js.
I also tried the revision from @DerekNguyen which looked like this:
import React from "react"
import { Link, graphql, StaticQuery } from "gatsby"
export default(data) => (
<div id="experience" className="section accent">
<div className="w-container">
<div className="section-title-group">
<Link to="#experience"><h2 className="section-heading centered">Experience</h2></Link>
</div>
<div className="columns w-row">
<StaticQuery
query={graphql`
query ExperienceQuery {
allMarkdownRemark(
limit: 2,
sort: { order: DESC, fields: [frontmatter___date]},
filter: {fileAbsolutePath: {regex: "/(experience)/"}}
) {
edges {
node {
id
frontmatter {
title
company_role
location
work_from
work_to
tags
}
excerpt
}
}
}
}
`}
render={data.allMarkdownRemark.edges.map(({ node }) => (
<div className="column-2 w-col w-col-4 w-col-stack" key={node.id}>
<div className="text-block"><strong>{node.frontmatter.title}</strong></div>
<div className="text-block-4">{node.frontmatter.company_role}</div>
<div className="text-block-4">{node.frontmatter.location}</div>
<div className="text-block-3">{node.frontmatter.work_from} – {node.frontmatter.work_to}</div>
<p className="paragraph">{node.frontmatter.excerpt}</p>
<div className="skill-div">{node.frontmatter.tags}</div>
</div>
))}
/>
</div>
</div>
</div>
);
However that also came with an error as well:
TypeError: Cannot read property 'edges' of undefined
Still working on it, but I think it is getting closer to the solution. Keep in mind I also would have to create it for the other variables.
Update: 2/10/2019
For those who want to see how I constructed the site using gatsby-starter, here it is below:
