Helpers for working with the filesystem.

Utilities for working with OS-specific file paths.

Platform-specific conventions for the line ending format (i.e., the "end-of-line").

Pretty-prints an analysis of the metafile JSON to a string. This is just for convenience to be able to match esbuild's pretty-printing exactly. If you want to customize it, you can just inspect the data in the metafile yourself.

A synchronous version of "analyzeMetafile".

A synchronous version of "build".

Converts log messages to formatted message strings suitable for printing in the terminal. This allows you to reuse the built-in behavior of esbuild's log message formatter. This is a batch-oriented API for efficiency.

A synchronous version of "formatMessages".

This configures the browser-based version of esbuild. It is necessary to call this first and wait for the returned promise to be resolved before making other API calls when using esbuild in the browser.

This function is similar to "build" but it serves the resulting files over HTTP on a localhost address with the specified port.

This function transforms a single JavaScript file. It can be used to minify JavaScript, convert TypeScript/JSX to JavaScript, or convert newer JavaScript to older JavaScript. It returns a promise that is either resolved with a "TransformResult" object or rejected with a "TransformFailure" object.

A synchronous version of "transform".

Copy a file or directory. The directory can have contents. Like cp -r. Requires the --allow-read and --allow-write flag.

Copy a file or directory. The directory can have contents. Like cp -r. Requires the --allow-read and --allow-write flag.

Detect the EOL character for string input. returns null if no newline

Ensures that a directory is empty. Deletes directory contents if the directory is not empty. If the directory does not exist, it is created. The directory itself is not deleted. Requires the --allow-read and --allow-write flag.

Ensures that a directory is empty. Deletes directory contents if the directory is not empty. If the directory does not exist, it is created. The directory itself is not deleted. Requires the --allow-read and --allow-write flag.

Ensures that the directory exists. If the directory structure does not exist, it is created. Like mkdir -p. Requires the --allow-read and --allow-write flag.

Ensures that the directory exists. If the directory structure does not exist, it is created. Like mkdir -p. Requires the --allow-read and --allow-write flag.

Ensures that the file exists. If the file that is requested to be created is in directories that do not exist. these directories are created. If the file already exists, it is NOTMODIFIED. Requires the --allow-read and --allow-write flag.

Ensures that the file exists. If the file that is requested to be created is in directories that do not exist, these directories are created. If the file already exists, it is NOT MODIFIED. Requires the --allow-read and --allow-write flag.

Ensures that the hard link exists. If the directory structure does not exist, it is created.

Ensures that the hard link exists. If the directory structure does not exist, it is created.

Ensures that the link exists. If the directory structure does not exist, it is created.

Ensures that the link exists. If the directory structure does not exist, it is created.

Test whether or not the given path exists by checking with the file system.

Test whether or not the given path exists by checking with the file system.

Expand the glob string from the specified root directory and yield each result as a WalkEntry object.

Synchronous version of expandGlob().

Format the file to the targeted EOL

Moves a file or directory

Moves a file or directory synchronously

Walks the file tree rooted at root, yielding each file or directory in the tree filtered according to the given options. The files are walked in lexical order, which makes the output deterministic but means that for very large directories walk() can be inefficient.

Same as walk() but uses synchronous ops

Determines the common path from a set of paths, using an optional separator, which defaults to the OS default separator.

Convert a glob string to a regular expression.

Test whether the given string is a glob

Like join(), but doesn't collapse "**/.." when globstar is true.

Like normalize(), but doesn't collapse "**/.." when globstar is true.

A parsed path object generated by path.parse() or consumed by path.format().
