Deno standard library

Index

archive	Tar is a utility for collecting multiple files (or any arbitrary data) into one archive file, while untar is the inverse utility to extract the files from an archive. Files are not compressed, only collected into the archive.
assert	A library of assertion functions. If the assertion is false an `AssertionError` will be thrown which will result in pretty-printed diff of failing assertion.
async	Provide help with asynchronous tasks like delays, debouncing, deferring, or pooling.
bytes	Provides helper functions to manipulate `Uint8Array` byte slices that are not included on the `Uint8Array` prototype.
cli	Tools for creating interactive command line tools.
collections	Pure functions for common tasks around collection types like arrays and objects. Heavily inspired by [Kotlin's `kotlin.collections`]`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/` package.
console	Functions for console-related tasks such as TTY text layout
crypto	Extensions to the Web Crypto supporting additional encryption APIs, but also delegating to the built-in APIs when possible.
csv	Reads and writes comma-separated values (CSV) files.
data_structures
datetime	Utilities for dealing with `Date` objects.
dotenv	Load environment variables from a `.env` file. Loaded variables are accessible in a configuration object returned by the `load()` function, as well as optionally exporting them to the process environment using the `export` option.
encoding
expect
flags
fmt
front_matter	Extracts front matter from strings.
fs	Helpers for working with the filesystem.
html	Functions for HTML tasks such as escaping or unescaping HTML entities
http	Provides user-friendly `serve` on top of Deno's native HTTP server and other utilities for creating HTTP servers and clients.
ini	`parse` and `stringify` for handling INI encoded data, such as the Desktop Entry specification. Values are parsed as strings by default to preserve data parity from the original. Customization is possible in the form of reviver/replacer functions like those in `JSON.parse` and `JSON.stringify`. Nested sections, repeated key names within a section, and key/value arrays are not supported, but will be preserved when using `IniMap`. Multi-line values are not supported and will throw a syntax error. White space padding and lines starting with '#', ';', or '//' will be treated as comments.
io	Utilities for working with Deno's readers, writers, and web streams.
json	Utilities for parsing streaming JSON data.
jsonc	`parse` function for parsing JSONC (JSON with Comments) strings.
log	Logging library with the support for terminal and file outputs. Also provides interfaces for building custom loggers.
media_types	Utility functions for media types (MIME types).
msgpack
net	Network utilities.
path	Utilities for working with OS-specific file paths.
permissions	Helpers for interacting with Deno's permissions system.
regexp	Functions for tasks related to regular expression (regexps), such as escaping text for interpolation into a regexp
semver	The semantic version parser.
signal	Higher level API for dealing with OS signals.
streams	Utilities for working with the Streams API.
testing
text
toml	`parse` and `stringify` for handling TOML encoded data. Be sure to read the supported types as not every spec is supported at the moment and the handling in TypeScript side is a bit different.
ulid	Utilities for generating and working with [Universally Unique Lexicographically Sortable Identifiers (ULIDs)]https://github.com/ulid/spec.
url	Utilities for working with URL paths.
uuid	Generators and validators for UUIDs for versions v1, v3, v4 and v5.
webgpu
yaml	`parse` and `stringify` for handling YAML encoded data.
