deno info

deno info displays information about a module's dependency tree. See Modules for more about how Deno resolves and caches dependencies.

When you pass a local file, deno info <file> automatically discovers a deno.json or deno.jsonc configuration file in the current directory or a parent directory. Use --config <file> to specify a different configuration file, or --no-config to disable automatic config discovery.

Dependency inspector works with any local or remote ES modules.

JSON output

Use --json to get machine-readable output, useful for tooling and CI:

›_

deno info --json main.ts

For npm dependencies, each entry in the npmPackages map includes a localPath field with the package's location in the on-disk Deno cache, which tooling can use to locate cached npm packages.

Cache location

deno info can be used to display information about cache location:

›_

deno info
DENO_DIR location: "/Users/deno/Library/Caches/deno"
Remote modules cache: "/Users/deno/Library/Caches/deno/deps"
TypeScript compiler cache: "/Users/deno/Library/Caches/deno/gen"

Command line usage:

deno info [OPTIONS] [file]

Show information about a module or the cache directories.

Get information about a module:

deno info jsr:@std/http/file-server

The following information is shown: local: Local path of the file type: JavaScript, TypeScript, or JSON emit: Local path of compiled source code (TypeScript only) dependencies: Dependency tree of the source file

Options

--allow-import, -I<IP_OR_HOSTNAME>optional

Allow importing from remote hosts. Optionally specify allowed IP addresses and host names, with ports as necessary. Default value: deno.land:443,jsr.io:443,esm.sh:443,raw.esm.sh:443,cdn.jsdelivr.net:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443.

--cert<FILE>

Load certificate authority from PEM encoded file.

--config, -c<FILE>

Configure different aspects of deno including TypeScript, linting, and code formatting. Typically the configuration file will be called deno.json or deno.jsonc and automatically detected; in that case this flag is not necessary.

--deny-import<IP_OR_HOSTNAME>optional

Deny importing from remote hosts. Optionally specify denied IP addresses and host names, with ports as necessary.

--env-file<FILE>optional

Load environment variables from local file Only the first environment variable with a given key is used. Existing process environment variables are not overwritten, so if variables with the same names already exist in the environment, their values will be preserved. Where multiple declarations for the same environment variable exist in your .env file, the first one encountered is applied. This is determined by the order of the files you pass as arguments.

--json

UNSTABLE: Outputs the information in JSON format.

--location<HREF>

Show files used for origin bound APIs like the Web Storage API when running a script with --location=<HREF>.

--minimum-dependency-age<minimum-dependency-age>

(Unstable) The age in minutes, ISO-8601 duration or RFC3339 absolute timestamp (e.g. '120' for two hours, 'P2D' for two days, '2025-09-16' for cutoff date, '2025-09-16T12:00:00+00:00' for cutoff time, '0' to disable).

--no-config

Disable automatic loading of the configuration file.

Dependency management options

--frozen<BOOLEAN>optional

Error out if lockfile is out of date.

--import-map<FILE>

Load import map file from local file or remote URL.

--lock<FILE>optional

Check the specified lock file. (If value is not provided, defaults to "./deno.lock").

--no-lock

Disable auto discovery of the lock file.

--no-npm

Do not resolve npm modules.

--no-remote

Do not resolve remote modules.

--node-modules-dir<MODE>optional

Selects the node_modules directory mode for npm packages (not a path). One of: auto (create a local node_modules directory and install npm packages into it), manual (use the existing local node_modules directory, do not modify it), none (do not use a local node_modules directory; resolve npm packages from the global cache). Defaults to auto when the flag is passed without a value.

--node-modules-linker<MODE>

Sets the linker mode for npm packages (isolated or hoisted).

--reload, -r<CACHE_BLOCKLIST>optional

Reload source code cache (recompile TypeScript). With no value, reloads everything. Pass a comma-separated list of specifiers to reload only those modules; npm: reloads all npm modules; npm:chalk reloads a single npm module; jsr:@std/http/file-server,jsr:@std/assert/assert-equals reloads specific modules.

--vendor<vendor>optional

Toggles local vendor folder usage for remote modules and a node_modules folder for npm packages.
