babel-code-frame
Advanced tools
Package description
The babel-code-frame package is a utility that allows developers to generate a string representing a code frame that highlights a specific portion of the code, typically used to point out syntax errors or other code issues. It can be used to enhance error messages with a visual context of where the issue is located in the source code.
Highlighting code
This feature allows you to highlight a specific part of the code. In the provided code sample, it highlights the word 'Foo' in the given rawLines string.
const { codeFrameColumns } = require('babel-code-frame');
const rawLines = `class Foo {\n constructor()\n}`;
const location = { start: { line: 1, column: 16 }, end: { line: 1, column: 19 } };
const result = codeFrameColumns(rawLines, location, { highlightCode: true });
console.log(result);Chalk is a popular npm package used for styling terminal strings. While it doesn't generate code frames, it can be used in conjunction with other tools to highlight specific parts of the text in the terminal, similar to how babel-code-frame highlights code.
ansi-styles is a package that provides ANSI escape codes for styling strings in the terminal. Like chalk, it can be used to style and highlight text but does not provide code frame generation.
Cardinal is a syntax highlighter for JavaScript code that can be used in the terminal. It provides functionality similar to babel-code-frame's highlighting feature but is focused on syntax highlighting rather than pinpointing specific code locations.
