@egomobile/dbml-renderer
dbml-renderer
renders DBML files to SVG images.
The tool was orginally implemented as CLI tool by softwaretechnik.berlin .
Install
npm install @egomobile/dbml-renderer
For instance, the following code will produce the image below:
import { parseDMBL } from "@egomobile/dbml-renderer";
const dbml = `Table users {
id integer
username varchar
role varchar
created_at timestamp
}
Table posts {
id integer [primary key]
title varchar
body text [note: 'Content of the post']
user_id integer
created_at timestamp
}
Ref: posts.user_id > users.id`
console.log(
parseDMBL(dbml, "svg")
);
The examples directory contains other input and output examples.
Testing
The tests can be run with npm test
. They use the examples available in the
examples
directory. Each .dbml
file is used as input to render each of the
available output formats.
The output of a test run is placed in .test-output
. In case the renderer has
been modified, the test output can be visually inspected and, confirmed the
output is good, the expectations can be updated by copying them with the
following command:
cp .test-output/* examples/
To aid the visual inspection, you can open .compare-test-output.html
to
compare side-by-side each generated SVG.
