Remove or edit existing items in the /data/radar
folder.
For a new release, create a folder of the release date (YYYY-MM-DD)
under ./data/radar
. e.g. ./data/radar/2024-03-01
.
The items are written in Markdown format (.md)
Each file has a meta header where the attributes of the item are listed:
---
title: "React"
ring: adopt
quadrant: languages-and-frameworks
tags: [frontend, coding]
---
Text goes here. You can use **markdown** here.
Following front-matter attributes are possible:
- title: Name of the Item
- quadrant: Quadrant. One of the configured quadrants in
config.quadrants
- ring: Ring section in radar. One of the configured rings in
config.rings
- tags: Optional tags for filtering.
- featured: (optional, default "true") If you set this to
false
, the item will not be visible in the radar quadrants but still be available in the overview.
The name of the .md file acts as item identifier and may overwrite items with the same name from older releases.
If an item is overwritten in a new release, the attributes from the new item are merged with the old ones, and a new history entry is created for that item.
You can integrate images in your markdown. Put the image files in the public/images
folder and
reference them

Your final file and folder structure should look like this:
├── about.md
├── config.json
├── package.json
├── public/
│ ├── images/
│ │ └── optional-content-image.png
│ ├── favicon.ico
│ └── logo.svg
└── radar/
├── 2023-12-31/

└── demo-item-3.md
Run npm run build
to build the radar and upload the files of the ./build
folder to your server.
You can view a development version of the radar by running npm run serve
and open the radar in
your browser at http://localhost:3000/techradar
or the path you specified via basePath
.
If you need to customize the radar's styles, you can add custom CSS rules to the ./src/custom.css
file.
Be aware that this might break with future versions of the radar as we use css-modules in the components which generates dynamic, hashed class names and the layout structure might change.
Therefore, it's advised the [attribute^=value]
selector that matches elements whose attribute
value begins
with a specified value. As an example, if you want to always show the subline in the header use
the following rule:
[class^="Logo_subline"] {
display: block;
opacity: 1;
}
If you want to include assets like images or fonts, use ../../public/
as the base path.
Adding a background image to the page could be archived like this:
body {
background: url("../../public/background.png");
}
Changing the font-family of the headlines:
h1,
h2,
h3 {
font-family: "Times New Roman", Times, Baskerville, Georgia, serif;
}
Changes to the css file will not be reflected in the development server. You need to
run npm run serve
or npm run build
to see the changes.
If you want to change core functionality of the radar, you can clone this repository and put your
radar's markdown-files, config.json and about.md in the data
folder. Run npm run build:data
to
parse the markdown files and create a data.json
and then run npm run dev
to start the
development server, which will be available at http://localhost:3000/techradar
or the path
you specified via basePath
.
