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 Jump to heading

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 Jump to heading

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:
info

Show info about cache or info related to source file

Options Jump to heading

--allow-import, -I
Jump to heading

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
Jump to heading

Load certificate authority from PEM encoded file.

--config, -c
Jump to heading

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
Jump to heading

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

--frozen-lockfile
Jump to heading

Error out if lockfile is out of date.

--import-map
Jump to heading

Load import map file from local file or remote URL.

--json
Jump to heading

UNSTABLE: Outputs the information in JSON format.

--location
Jump to heading

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

--lock
Jump to heading

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

--min-dep-age
Jump to heading

(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-check
Jump to heading

Skip type-checking. If the value of "remote" is supplied, diagnostic errors from remote modules will be ignored.

--no-config
Jump to heading

Disable automatic loading of the configuration file.

--no-lock
Jump to heading

Disable auto discovery of the lock file.

--no-npm
Jump to heading

Do not resolve npm modules.

--no-remote
Jump to heading

Do not resolve remote modules.

--node-modules-dir
Jump to heading

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
Jump to heading

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

--reload, -r
Jump to heading

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.

--unsafely-ignore-certificate-errors
Jump to heading

DANGER: Disables verification of TLS certificates.

--vendor
Jump to heading

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