NAME
npm-install-test - Install package(s) and run tests
Synopsis
npm install-test [<package-spec> ...]
alias: it
Description
This command runs an npm install followed immediately by an npm test.
It takes exactly the same arguments as npm install.
Configuration
save
o Default: true unless when using npm update where it defaults to
false
o Type: Boolean
Save installed packages to a package.json file as dependencies.
When used with the npm rm command, removes the dependency from
package.json.
Will also prevent writing to package-lock.json if set to false.
save-exact
o Default: false
o Type: Boolean
Dependencies saved to package.json will be configured with an exact
version rather than using npm's default semver range operator.
global
o Default: false
o Type: Boolean
Operates in "global" mode, so that packages are installed into the
prefix folder instead of the current working directory. See npm help
folders for more on the differences in behavior.
o packages are installed into the {prefix}/lib/node_modules folder,
instead of the current working directory.
o bin files are linked to {prefix}/bin
o man pages are linked to {prefix}/share/man
install-strategy
o Default: "hoisted"
o 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: (experimental)
install in node_modules/.store, link in place, unhoisted.
legacy-bundling
o Default: false
o Type: Boolean
o 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
o Default: false
o Type: Boolean
o 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
o Default: 'dev' if the NODE_ENV environment variable is set to
'production'; otherwise, empty.
o 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 or npm-shrinkwrap.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
o Default:
o 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=<type>.
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
o Default: false
o 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.
prefer-dedupe
o Default: false
o Type: Boolean
Prefer to deduplicate packages if possible, rather than choosing a
newer version of a dependency.
package-lock
o Default: true
o Type: Boolean
If set to false, then ignore package-lock.json files when installing.
This will also prevent writing package-lock.json if save is true.
package-lock-only
o Default: false
o Type: Boolean
If set to true, the current operation will only use the package-
lock.json, ignoring node_modules.
For update this means only the package-lock.json will be updated,
instead of checking node_modules and downloading dependencies.
For list this means the output will be based on the tree described by
the package-lock.json, rather than the contents of node_modules.
foreground-scripts
o Default: false unless when using npm pack or npm publish where it
defaults to true
o 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
o Default: false
o 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.
allow-git
o Default: "all"
o 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.
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 installed. Also allows git dependencies to be fetched for
other commands like npm view
audit
o Default: true
o 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 help audit for details on what is submitted.
before
o Default: null
o Type: null or Date
If passed to npm install, will rebuild the npm tree such that only
versions that were available on or before the given date are installed.
If there are no versions available for the current set of dependencies,
the command will error.
If the requested version is a dist-tag and the given tag does not pass
the --before filter, the most recent version less than or equal to that
tag will be used. For example, foo@latest might install foo@1.2 even
though latest is 2.0.
This config cannot be used with: min-release-age
min-release-age
o Default: null
o Type: null or Number
If set, npm will build the npm tree such that only versions that were
available more than the given number of days ago will be installed. If
there are no versions available for the current set of dependencies,
the command will error.
This flag is a complement to before, which accepts an exact date
instead of a relative number of days.
This config cannot be used with: before
This value is not exported to the environment for child processes.
bin-links
o Default: true
o 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
o Default: true
o Type: Boolean
When "true" displays the message at the end of each npm install
acknowledging the number of dependencies looking for funding. See npm
help fund for details.
dry-run
o Default: false
o 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.
cpu
o Default: null
o Type: null or String
Override CPU architecture of native modules to install. Acceptable
values are same as cpu field of package.json, which comes from
process.arch.
os
o Default: null
o Type: null or String
Override OS of native modules to install. Acceptable values are same as
os field of package.json, which comes from process.platform.
libc
o Default: null
o Type: null or String
Override libc of native modules to install. Acceptable values are same
as libc field of package.json
workspace
o Default:
o 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:
o Workspace names
o Path to a workspace directory
o 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
o Default: null
o 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:
o 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
o Default: false
o 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
o Default: false
o 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.
