#Setting Deno CLI options

A subset of Deno CLI options can be specified with dedicated properties in config files.

Deno options are effectively only applied to deno commands that accept them.

#Permissions

Deno permissions can be specified using allow.

# `allow` can be a list of permission names
allow:
  - net
  - read

scripts:
  start:
    cmd: server.ts
    allow: # or a map
      net: 127.0.0.1
      read: true # allow all reads

#TS/Deno config file

Use the config property to specify a Deno config file or tsconfig (Deno's --config option).

scripts:
  start:
    cmd: server.ts
    config: tsconfig.json

#Import maps

Import maps are specified in importMap.

scripts:
  start:
    cmd: deno run --unstable server.ts
    importMap: import_map.json

#Inspect

inspect and inspectBrk correspond to the --inspect and --inspect-brk options.

scripts:
  start:
    cmd: server.ts
    inspect: 127.0.0.1:9229 # use inspect: true to apply the default settings

#Lockfile

The lock property sets the namesake Deno option.

scripts:
  start:
    cmd: server.ts
    lock: lock.json

ℹ️ Setting this option doesn't create a lock file: you will have to create/update it by passing the --lock-write option manually to your script at the appropriate time. More info here.

#Reload

Reload source code cache (recompile TypeScript).

scripts:
  start:
    cmd: server.ts
    reload: true                  # Reload everything
    reload: https://deno.land/std # Reload only standard modules
    reload:                       # Reload specific modules
      - https://deno.land/std/fs/utils.ts
      - https://deno.land/std/fmt/colors.ts

#Other boolean flags

The --cached-only, --no-check, --no-remote, --quiet, --unstable options can be applied using the following properties:

scripts:
  start:
    cmd: server.ts
    cachedOnly: true
    noCheck: true
    noRemote: true
    quiet: true
    unstable: true

#Log

The log property corresponds to deno's --log-level. The allowed values are debug and info.

scripts:
  start:
    cmd: server.ts
    log: debug

#Cert

Specify a PEM certificate for http client in cert.

scripts:
  start:
    cmd: server.ts
    cert: certificate.pem

#V8 flags

V8 flags can be specified like permissions under the v8Flags property.

v8Flags:
  - expose-gc
  - async-stack-trace

scripts:
  start:
    cmd: server.ts
    v8Flags:
      logfile: v8.log
