Practical guides, not placeholder pages.

How-to guides Start with release sequencing and command-line usage, then move into feature-specific references.

Advanced protection Browse cross-file controls like Replace Globals and Protect Members when a build spans multiple scripts.

npm CLI Presets and Options

Applies tonpm CLI, Node API, build plugins

Use presets for a quick start, then override individual HTTP API options from config or CI when a release needs tighter behavior.

Inspect presets from the CLI

jso-protector --list-presets
jso-protector --list-presets --json

standard
Core string encoding, string movement, name replacement, and compression.

balanced
Adds short local names, deep obfuscation, code transposition, string encryption, and flat transform.

maximum
Adds member/global renaming, member movement, and low dead-code insertion.

Inspect option names

jso-protector --list-options
jso-protector --list-options --json

The JSON output is useful for internal release tooling that wants to render approved option choices or validate CI overrides.

Inspect resolved config

Use --validate-config --json to catch malformed fields, missing credentials, invalid endpoint URLs, bad size budgets, and likely option-name typos before a release job runs.

jso-protector --config jso.config.json --validate-config --json

Use --print-config --json to see merged settings without leaking dashboard credentials.

jso-protector --config jso.config.json --print-config --json

Common option groups

Strings `EncodeStrings`, `MoveStrings`, `EncryptStrings`	Names `ReplaceNames`, `RenameGlobals`, `RenameMembers`, `VariableExclusion`, `IdentityStyle`
Compression `SelfCompression`, `SelfCompressionMinSize`, `CompressionRatio`	Control flow `DeepObfuscate`, `ReorderCode`, `FlatTransform`, `AddDeadCode`, `DeadcodeLevel`
Locks `LockDomain`, `LockDomainList`, `LockDomainMsg`, `LockDate`, `LockDateValue`, `LockDateMsg`	Output and runtime `OptimizationMode`, `WriteFormats`, `WriteFormats_KeepIndent`, `WriteFormats_LineNumbers`

Override from CI

jso-protector --config jso.config.json --option LockDomain=true --option LockDomainList=example.com

Repeat --reserved-name to preserve public entry points without editing shared config.

jso-protector --config jso.config.json --reserved-name "^PublicApi$" --reserved-name "^renderWidget$"
