Fetcher can check for a newer Express Generator version and optionally install it.

check_for_update      = true
automatic_update      = true
update_check_interval = 24

Option behavior:

• check_for_update

Enables update checks when fetcher runs.

• automatic_update

If a newer version exists, fetcher downloads and installs it automatically.

• update_check_interval

Minimum hours between update checks.

check_for_update      = true
automatic_update      = true
update_check_interval = 24

Use when you want Express Generator to stay current with no manual steps.

check_for_update      = true
automatic_update      = false
update_check_interval = 24

Use when updates must be reviewed before installation.

check_for_update = false

Use in controlled environments where versions are pinned externally.

Check for updates but do not auto-install:

node ./bin/fetch.js --check-for-update true --automatic-update false --update-check-interval 0

Disable update checks for this run:

node ./bin/fetch.js --check-for-update false

Force an update check immediately:

node ./bin/fetch.js --check-for-update true --update-check-interval 0

• update_check_interval is measured in hours.
• The last check timestamp is stored in ./bin/res/update-check.json.
• Update checks run only when check_for_update is enabled.
• Auto-update replaces files in the ./bin folder.
• Keep your custom changes in user settings files and pass them with –settings.

• Fetcher (fetch.js)
