actions/checkout v4 persist-credentials default true README
💡 Result:
In actions/checkout v4, the default value for the persist-credentials input is true [1][2][3]. When this setting is enabled (as it is by default), the authentication token used by the action is persisted in the local git configuration [1][4]. This allows subsequent steps in the same job to execute authenticated git commands directly without requiring additional configuration [1][4]. The token is automatically removed during the post-job cleanup phase [1][4]. If you wish to prevent this behavior, you must explicitly set persist-credentials to false in your workflow file [1][4]: - uses: actions/checkout@v4 with: persist-credentials: false While there has been public discussion and community proposals to change this default to false to reduce potential security risks, the default remains true in version 4 [5][6][7]. Note that the GITHUB_TOKEN itself is accessible to all steps in a job, but using persist-credentials: false ensures that the token is not automatically added to the git configuration for implicit use by git commands [6][7].

Disable persistence for the checkout token.
actions/checkout@v4 persists credentials by default, and this job runs npm ci || npm install afterward. Set persist-credentials: false unless the remaining steps need authenticated git access, so lifecycle scripts cannot inherit the persisted token.

Node.js Release schedule Node 18 end-of-life April 30 2025 Node 24 supported
💡 Result:
As of July 27, 2026, the status of the requested Node.js versions is as follows: Node.js 18 (Hydrogen) reached its End-of-Life (EOL) on April 30, 2025 [1][2][3]. It no longer receives security patches or updates [1][4]. Node.js 24 (Krypton) is currently a supported, Active Long-Term Support (LTS) release [2][5][6]. It is scheduled to remain in support until its End-of-Life date on April 30, 2028 [7][5][8]. In the current Node.js release model, active production environments should prioritize using Active or Maintenance LTS versions [2][9]. As of this date, Node.js 26 is the Current release, Node.js 24 is in Active LTS, and Node.js 22 is in Maintenance LTS [6].

npm documentation npm ci --install-strategy=npm install install-strategy behavior
💡 Result:
The --install-strategy configuration option is supported by both npm install and npm ci [1][2]. It determines how packages are laid out within the node_modules directory [1][2]. The available strategies are: hoisted (default): The standard behavior that installs non-duplicated dependencies at the top level of node_modules and places duplicated dependencies within the directory structure as necessary [1][2]. nested (formerly --legacy-bundling): Installs packages exactly where they are depended on without hoisting, which can lead to deep directory structures and duplicate package installations [1][2]. shallow (formerly --global-style): Installs only direct dependencies at the top level of node_modules, while hoisting deeper dependencies [1][2]. linked: Installs packages in node_modules/.store and creates links in place, keeping the node_modules tree unhoisted [1][2]. This strategy is recommended for package authors during development to help identify undeclared ("phantom") dependencies, as it ensures that only declared dependencies are accessible [1][2]. The --install-strategy option serves as the modern replacement for the deprecated --legacy-bundling and --global-style flags [1][2]. When using npm ci, this configuration allows you to control the resulting node_modules layout during automated or reproducible installation processes [1][3].

Don’t fall back to npm install on dependency install errors.
The workflow already has package-lock.json; npm ci is the intended lockfile-backed install for CI, and || npm install can let formatting run with a different dependency tree if the lockfile/integrity check fails.
