--- title: npm-install-ci-test section: 1 description: Install a project with a clean slate and run tests --- ### Synopsis ```bash npm install-ci-test aliases: cit, clean-install-test, sit ``` ### Description This command runs `npm ci` followed immediately by `npm test`. ### Configuration #### `install-strategy` * Default: "hoisted" * Type: "hoisted", "nested", "shallow", or "linked" Sets the strategy for installing packages in node_modules. hoisted (default): Install non-duplicated in top-level, and duplicated as necessary within directory structure. nested: (formerly --legacy-bundling) install in place, no hoisting. shallow (formerly --global-style) only install direct deps at top-level. linked: install in node_modules/.store, link in place, unhoisted. We recommend that package authors use `--install-strategy=linked` during development to catch undeclared ("phantom") dependencies before publishing: the isolated layout only exposes a package's declared dependencies, so an `import` of a package that was never added to `package.json` can fail instead of resolving by accident and shipping broken. See [Catching undeclared ("phantom") dependencies](/using-npm/developers#catching-undeclared-phantom-dependencies). #### `legacy-bundling` * Default: false * Type: Boolean * DEPRECATED: This option has been deprecated in favor of `--install-strategy=nested` Instead of hoisting package installs in `node_modules`, install packages in the same manner that they are depended on. This may cause very deep directory structures and duplicate package installs as there is no de-duplicating. Sets `--install-strategy=nested`. #### `global-style` * Default: false * Type: Boolean * DEPRECATED: This option has been deprecated in favor of `--install-strategy=shallow` Only install direct dependencies in the top level `node_modules`, but hoist on deeper dependencies. Sets `--install-strategy=shallow`. #### `omit` * Default: 'dev' if the `NODE_ENV` environment variable is set to 'production'; otherwise, empty. * Type: "dev", "optional", or "peer" (can be set multiple times) Dependency types to omit from the installation tree on disk. Note that these dependencies _are_ still resolved and added to the `package-lock.json` file. They are just not physically installed on disk. If a package type appears in both the `--include` and `--omit` lists, then it will be included. If the resulting omit list includes `'dev'`, then the `NODE_ENV` environment variable will be set to `'production'` for all lifecycle scripts. #### `include` * Default: * Type: "prod", "dev", "optional", or "peer" (can be set multiple times) Option that allows for defining which types of dependencies to install. This is the inverse of `--omit=`. Dependency types specified in `--include` will not be omitted, regardless of the order in which omit/include are specified on the command-line. #### `strict-peer-deps` * Default: false * Type: Boolean If set to `true`, and `--legacy-peer-deps` is not set, then _any_ conflicting `peerDependencies` will be treated as an install failure, even if npm could reasonably guess the appropriate resolution based on non-peer dependency relationships. By default, conflicting `peerDependencies` deep in the dependency graph will be resolved using the nearest non-peer dependency specification, even if doing so will result in some packages receiving a peer dependency outside the range set in their package's `peerDependencies` object. When such an override is performed, a warning is printed, explaining the conflict and the packages involved. If `--strict-peer-deps` is set, then this warning is treated as a failure. #### `foreground-scripts` * Default: `false` unless when using `npm pack` or `npm publish` where it defaults to `true` * Type: Boolean Run all build scripts (ie, `preinstall`, `install`, and `postinstall`) scripts for installed packages in the foreground process, sharing standard input, output, and error with the main npm process. Note that this will generally make installs run slower, and be much noisier, but can be useful for debugging. #### `ignore-scripts` * Default: false * Type: Boolean If true, npm does not run scripts specified in package.json files. Note that commands explicitly intended to run a particular script, such as `npm start`, `npm stop`, `npm restart`, `npm test`, and `npm run` will still run their intended script if `ignore-scripts` is set, but they will *not* run any pre- or post-scripts. Setting `ignore-scripts` also disables `.npm-extension` execution, as if `ignore-extension` were set. #### `allow-directory` * Default: "all" * Type: "all", "none", or "root" Limits the ability for npm to install dependencies from directories. That is, dependencies that point to a directory instead of a version or semver range. Please note that this could leave your tree incomplete and some packages may not function as intended or designed. Changing this setting will not remove dependencies that are already installed. `all` allows any directories to be installed. `none` prevents any directories from being installed. `root` only allows directories defined in your project's package.json to be installed. Also allows directory dependencies to be used for other commands like `npm view` #### `allow-file` * Default: "all" * Type: "all", "none", or "root" Limits the ability for npm to install dependencies from tarball files. That is, dependencies that point to a local tarball file instead of a version or semver range. Please note that this could leave your tree incomplete and some packages may not function as intended or designed. Changing this setting will not remove dependencies that are already installed. `all` allows any tarball file to be installed. `none` prevents any tarball file from being installed. `root` only allows tarball files defined in your project's package.json to be installed. Also allows tarball file dependencies to be used for other commands like `npm view` #### `allow-git` * Default: "none" * Type: "all", "none", or "root" Limits the ability for npm to fetch dependencies from git references. That is, dependencies that point to a git repo instead of a version or semver range. Please note that this could leave your tree incomplete and some packages may not function as intended or designed. Changing this setting will not remove dependencies that are already installed. As of npm 12 the default is `none`. Git dependencies run `git` against a remote repo and may install configuration the project does not control. Opt in explicitly per project (in `.npmrc`) or per command (on the CLI) when you need git deps. `all` allows any git dependencies to be fetched and installed. `none` prevents any git dependencies from being fetched and installed. `root` only allows git dependencies defined in your project's package.json to be fetched and installed. Also allows git dependencies to be fetched for other commands like `npm view` #### `allow-remote` * Default: "none" * Type: "all", "none", or "root" Limits the ability for npm to fetch dependencies from urls. That is, dependencies that point to a tarball url instead of a version or semver range. Please note that this could leave your tree incomplete and some packages may not function as intended or designed. Changing this setting will not remove dependencies that are already installed. As of npm 12 the default is `none`. Tarballs that share a hostname with the configured registry (the typical case for the npm registry, GitHub Packages, and most private registries) are still installed normally. If your registry serves tarballs from a different host, set `replace-registry-host` or override this setting. Opt in explicitly per project (in `.npmrc`) or per command (on the CLI) when you intentionally install from a URL. `all` allows any url to be installed. `none` prevents any url from being installed. `root` only allows urls defined in your project's package.json to be installed. Also allows url dependencies to be used for other commands like `npm view` #### `allow-scripts` * Default: "" * Type: String (can be set multiple times) Comma-separated list of packages whose install-time lifecycle scripts (`preinstall`, `install`, `postinstall`, and `prepare` for non-registry dependencies) are allowed to run. This setting is intended for one-off and global contexts: `npm exec`, `npx`, and `npm install -g`, where no project `package.json` is involved. For team-wide policy in a project, use the `allowScripts` field in `package.json` (which also supports explicit denials), or configure it in `.npmrc`. Passing `--allow-scripts` on the command line during a project-scoped `npm install`, `ci`, `update`, or `rebuild` is an error. Each name is matched against a dependency's resolved identity, not against the package's self-reported name. `--ignore-scripts` and `--dangerously-allow-all-scripts` both override this setting. This value is not exported to the environment for child processes. #### `strict-allow-scripts` * Default: false * Type: Boolean If `true`, turn the install-script policy from a warning into a hard error: any dependency with install scripts that is not covered by `allowScripts` will fail the install instead of being blocked with a warning. Dependencies explicitly denied with `false` in `allowScripts` are always silently skipped; this setting only affects unreviewed entries (packages with install scripts that are neither approved nor denied). `--ignore-scripts` and `--dangerously-allow-all-scripts` both override this setting. Optional dependencies that cannot be installed on the current platform or engine (a non-matching `os`, `cpu`, or `libc`) are not flagged, because their install scripts never run. #### `dangerously-allow-all-scripts` * Default: false * Type: Boolean If `true`, bypass the `allowScripts` policy entirely and run every dependency install script regardless of whether it was approved or denied. Intended as a migration escape hatch only; its use is strongly discouraged. `--ignore-scripts` still takes precedence over this setting. #### `audit` * Default: true * Type: Boolean When "true" submit audit reports alongside the current npm command to the default registry and all registries configured for scopes. See the documentation for [`npm audit`](/commands/npm-audit) for details on what is submitted. #### `bin-links` * Default: true * Type: Boolean Tells npm to create symlinks (or `.cmd` shims on Windows) for package executables. Set to false to have it not do this. This can be used to work around the fact that some file systems don't support symlinks, even on ostensibly Unix systems. #### `fund` * Default: true * Type: Boolean When "true" displays the message at the end of each `npm install` acknowledging the number of dependencies looking for funding. See [`npm fund`](/commands/npm-fund) for details. #### `dry-run` * Default: false * Type: Boolean Indicates that you don't want npm to make any changes and that it should only report what it would have done. This can be passed into any of the commands that modify your local installation, eg, `install`, `update`, `dedupe`, `uninstall`, as well as `pack` and `publish`. Note: This is NOT honored by other network related commands, eg `dist-tags`, `owner`, etc. #### `workspace` * Default: * Type: String (can be set multiple times) Enable running a command in the context of the configured workspaces of the current project while filtering by running only the workspaces defined by this configuration option. Valid values for the `workspace` config are either: * Workspace names * Path to a workspace directory * Path to a parent workspace directory (will result in selecting all workspaces within that folder) When set for the `npm init` command, this may be set to the folder of a workspace which does not yet exist, to create the folder and set it up as a brand new workspace within the project. This value is not exported to the environment for child processes. #### `workspaces` * Default: null * Type: null or Boolean Set to true to run the command in the context of **all** configured workspaces. Explicitly setting this to false will cause commands like `install` to ignore workspaces altogether. When not set explicitly: - Commands that operate on the `node_modules` tree (install, update, etc.) will link workspaces into the `node_modules` folder. - Commands that do other things (test, exec, publish, etc.) will operate on the root project, _unless_ one or more workspaces are specified in the `workspace` config. This value is not exported to the environment for child processes. #### `include-workspace-root` * Default: false * Type: Boolean Include the workspace root when workspaces are enabled for a command. When false, specifying individual workspaces via the `workspace` config, or all workspaces via the `workspaces` flag, will cause npm to operate only on the specified workspaces, and not on the root project. This value is not exported to the environment for child processes. #### `install-links` * Default: false * Type: Boolean When set file: protocol dependencies will be packed and installed as regular dependencies instead of creating a symlink. This option has no effect on workspaces. ### See Also * [npm install-test](/commands/npm-install-test) * [npm ci](/commands/npm-ci) * [npm test](/commands/npm-test)
