@babel/code-frame
Advanced tools
Generate errors that contain a code frame that point to source locations.
The @babel/code-frame package is used to generate a string representing code with a specific error highlighted. It is often used to produce more readable error messages in development tools by showing the code snippet where an error has occurred along with line and column numbers.
Highlighting syntax errors in code
This feature allows developers to highlight syntax errors in their code. The code sample shows how to use the codeFrameColumns function to generate a string that highlights the location of an error in the source code.
const { codeFrameColumns } = require('@babel/code-frame');
const rawLines = `class Foo {
constructor()
}
`;
const location = { start: { line: 2, column: 15 } };
const result = codeFrameColumns(rawLines, location, {
highlightCode: true
});
console.log(result);Chalk is a popular npm package for styling terminal strings. While it doesn't generate code frames, it can be used to colorize text and could be combined with other tools to highlight specific parts of code in the terminal.
Cardinal is a syntax highlighter for JavaScript code that can be used in the terminal. It's similar to @babel/code-frame in that it can be used to make code more readable, but it focuses on syntax highlighting rather than pinpointing specific locations of errors.
Highlight.js is a syntax highlighter for the web. It supports many languages and can be used to highlight code blocks on web pages. Unlike @babel/code-frame, it is not specifically designed for highlighting error locations, but it can be used to enhance the readability of code snippets.
