Documented steps cd into the project that contains the package.json you want to edit Set a single field: npm pkg set description='My package' Set multiple fields in one call using dot-separated key notation for nested paths: npm pkg set description='Awesome package' engines.node='>=10' The key is the object path (e.g. scripts.build maps to package.json scripts.build); the value is after the equals sign npm rewrites package.json in place, respecting the file's existing indentation and applying validation before it saves Add an entry to a map field like a new bin: npm pkg set bin.mycommand=cli.js Confirm the result with npm pkg get <field> or by reading package.json Known gotchas Values are written as strings by default; pass --json so values are parsed with JSON.parse (needed to save booleans/numbers, e.g. private=true) Quote values that contain spaces or shell-special characters so the shell doesn't split them Nested map keys use dot notation; array items use [index] and empty [] to append --force removes npm's protections against mistakes and specifically allows clobbering existing values; avoid it unless you intend to overwrite npm pkg respects existing indentation and normalizes the file on save, so formatting may shift slightly
