NAME
pkg-js-tools - collection of tools to aid packaging Node modules in Debian.
WORKING WITH SALSA.DEBIAN.ORG REPOSITORY
To use salsa(1) with pkg-javascript configuration, add something like that in
your .bashrc:
alias js-salsa='salsa --conf-file +/usr/share/pkg-js-tools/pkg-js-salsa.conf'
Then you can use salsa simply. Some examples:
• if you created a local repo and want to create and push it on
salsa ⟨https://salsa.debian.org/js-team⟩, launch simply:
js-salsa push_repo .
• to configure a repo already pushed:
js-salsa update_safe node-foobar
• to clone locally a js-team package:
js-salsa co node-foobar
See salsa(1) for more.
DEBHELPER ADDON
pkg-js-tools debhelper addon is automatically loaded if a package
build-depends on dh-sequence-nodejs or (old fashion) if dh is called
with --with nodejs in debian/rules.
Quick use
Examples of basic migration to pkg-js-tools:
Switch test and install to pkg-js-tools ⟨https://salsa.debian.org/js-team/node-static-
module/-/commit/2c6d9fb1⟩
How it works
pkg-js-tools provides hooks for these steps:
┌─────────────────────────────────────────────────────────────────────────────────────────┐
│ Step Comment │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ configure populate node_modules/ │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ build build components and main module │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ test test components and main module │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ install install components and main │
│ module │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ installdocs can auto-generate docs for each │
│ component │
├─────────────────────────────────────────────────────────────────────────────────────────┤
│ clean clean pkg-js-tools stuff │
└─────────────────────────────────────────────────────────────────────────────────────────┘
Technically, it adds --buildsystem=nodejs to the corresponding dh_auto_<step>
command.
Important note. Here:
• component is the directory name of a submodule (uscan(1) component or .br additional
components listed in debian/nodejs/additional_components).
Example: types-glob
• module is the npmjs name. Example: @types/glob
See Group Sources Tutorial ⟨https://wiki.debian.org/Javascript/GroupSourcesTutorial⟩
for more about embedding components.
Details:
• dh_auto_clean, cleans files automatically installed by pkg-js-tools
itself
• dh_auto_configure, automatically populates node_modules directory:
• links embedded components
• links global modules listed in debian/nodejs/extlinks
• copies global modules listed in debian/nodejs/extcopies
• dh_auto_build, Remember to add a dh_auto_build --buildsystem=nodejs
in override_dh_auto_build section if your debian/rules file has such
section, else this step will be ignored. Builds:
• components by launching sh -ex debian/nodejs/<component-name>/build in
this file exists
• main module by launching sh -ex debian/nodejs/build if exists
• dh_auto_test, tests:
• components by launching sh -ex debian/nodejs/<component-name>/test if
this file exists
• main module by launching sh -ex debian/tests/pkg-js/test if this file
exists. This test is also used by pkg-js-autopkgtest(7) during autopkgtest.
If you want to have a different test during build, set this test in
debian/nodejs/test.
• dh_auto_install: installs modules in the good directories and provides
some debhelper variables to be used in debian/control. Note that if your
package provides more that one binary package, you have to use some
debian/<package-name>.install files to distribute the files.
Steps:
• components: determine files to install using the same algorithm than
main module
and install them:
• nowhere if component if debian/nodejs/submodules exists and component
isn't listed in it (an empty debian/nodejs/submodules drops all .br components)
• nowhere if component is listed in debian/nodejs/additional_components
with a "!" prefix
• in main nodejs directories if component is listed in
debian/nodejs/root_modules
• else: in a node_modules subdirectory of main module
• main module, determine files to install (see below) and install them
in the "good" directory:
• if "architecture" is "all": /usr/share/nodejs
• else: /usr/lib/${DEB_HOST_MULTIARCH}/nodejs
• links: builds symlinks listed in debian/nodejs/links. Same usage
as debian/links except that source or destination not starting with /
are related to arch path
(/usr/share/nodejs or /usr/lib/<gnu-arch>/nodejs)
• Build pkgjs-lock\.json files: if package "maybe a bundle"
(built with webpack, browserify,\.\.\.), pkg-js-tools builds a
pkgjs-lock.json for each module. This files may help in Debian
transitions
• Variables usable in debian/control:
• ${nodejs:Version}: the version of nodejs used during build
• ${nodejs:Provides}: virtual names to be added into "Provides:" field.
This lists all modules installed in nodejs root directories
• ${nodeFoo:Provides}: for a source package that provides several binary
packages, dh-sequence-nodejs filters ${nodejs:Provides} for each
binary package. The package name is converted into its camelcase name:
node-jest-worker becomes nodeJestWorker
• ${nodejs:BuiltUsing}: when package "maybe a bundle", lists packages
and versions used to build package. Use it in
XB-Javascript-Built-Using field
• dh_installdocs: dh-sequence-nodejs provides a tool named
dh_nodejs_autodocs which can be used in a override_dh_installdocs
to automatically generate documentation for each component. See related
manpage
• dh_install: dh-sequence-nodejs provides a tool named
dh_nodejs_build_debug_package which can be used to build a separate
debug package with sourcemap files when package size is too big. See related
manpage
Automatically detect some additional components
Starting from 0.12.0, dh-sequence-nodejs automatically reads lerna.conf and
reads "packages" field to find additional components.
Starting from 0.12.7, it does the same when package.json has a "workspaces"
field.
This auto-detection automatically drops "test" and "tests" directories. You
can override this behavior using debian/additional_components.
If a component should not be considered, insert its name preceded by a "!" in
debian/nodejs/additional_components.
To disable this feature, use dh-sequence-nodejs-no-lerna.
Algorithm to determine files to install
pkg-js-tools tries to reproduce npm(1) behavior: it reads package.json
and/or .npmignore files to determine files to install except that it drops
licenses, *.md, doc*, example*, test*, makefiles,...`.
This behavior is overridden if:
• debian/nodejs/install (or debian/nodejs/<component-name>/install)
exists. This file uses the same format than debian/install.
• debian/nodejs/files (or debian/nodejs/<component-name>/files) exists.
the content of this file replaces "files" entry of package.json
pkg-js-tools files
• all steps:
• debian/nodejs/additional_components is used to set some
subdirectories that should be considered as components even if they
are not listed in debian/watch. Content example: packages/*.
Important note: in this example, component name is packages/foo in
every other files, including paths
• debian/nodejs/main is used to indicates where is the main module.
In a package containing only components (bundle package), you should
choose one of them as main component
• configure step:
• debian/build_modules additional modules needed to build, will be
linked in node_modules directory
• debian/nodejs/component_links lists needed links between components:
links ../../component-src in component-dst/node_modules/component-src-name
• debian/nodejs/<component-name>/nolink avoids node_modules links
creation for this component (configuration step)
• debian/nodejs/extlinks lists installed node modules that should be
linked into node_modules directory (modules are searched using nodejs .br algorithm).
You can mark them with "test" to avoid errors when build
profile contains nocheck
• debian/nodejs/extcopies lists installed node modules that should be
copied into node_modules directory. You can also mark them with "test"
• debian/nodejs/<component>/extlinks lists installed node modules that
should be linked in <component>/node_modules directory (test flag available)
• debian/nodejs/<component>/extcopies lists installed node modules that
should be copied in <component>/node_modules directory (test flag available)
• build step:
• debian/nodejs/build custom build. An empty file stops auto build
• debian/nodejs/<component>/build: same for components
• debian/nodejs/build_order orders components build (one component
per line). Else components are built in alphabetic order except components
declared in debian/nodejs/component_links: a component that depends
on another is built after
• test step:
• debian/tests/test_modules/: additional modules needed for running tests can be
added to this directory as subdirectories, which will be linked in node_modules
directory during test step only
• debian/tests/pkg-js/test: script to launch during test
(launched with set -e)
• debian/tests/pkg-js/files: lists other files than
debian/tests/test_modules/fP and installed files needed for autopkgtest
(default: test*)
• debian/nodejs/test: overwrite debian/tests/pkg-js/test during
build if test differs in build and autopkgtest
• debian/nodejs/<component-name>/test: same for components
(launched during build only)
• autopkgtest files:
• debian/tests/autopkgtest-pkg-nodejs\.conf: autodep8 configuration file
which can be used to add packages or restrictions during autopkgtest only
• extra_depends=p1, p2, p3 permits one to add p1, p2 and p3 packages
• extra-restrictions=needs-internet permits one to add additional restrictions
during autopkgtest
• debian/tests/pkg-js/require-name: contains the name to use in
autopkgtest require test instead of package.json value
• install step:
• debian/nodejs/submodules lists components to install (all if missing)
• debian/nodejs/root_modules lists components to install in nodejs root
directory (instead of node_modules subdirectory). If this file
contains *, all components are installed in root directory
• debian/nodejs/files overwrites package.json#files field.
• debian/nodejs/<component-name>/files overwrites package.json#files
field. An empty file avoid any install
• debian/nodejs/name overwrites package.json#name field.
• debian/nodejs/<component-name>/name overwrites package.json#name
• debian/nodejs/install overwrites debian/nodejs/files: same usage as
debian/install except that destination not starting with / are related to
arch path (/usr/share/nodejs or /usr/lib/<gnu-arch>/nodejs)
• debian/nodejs/<component-name>/install same as debian/nodejs/install
for components
• link step:
• debian/nodejs/links: same usage as debian/links except that source or
destination not starting with / are related to arch path
(/usr/share/nodejs or /usr/lib/<gnu-arch>/nodejs)
To install a component in another directory, set its files in
debian/install.
Example:
• debian/control
...
Testsuite: autopkgtest-pkg-nodejs
Build-Depends: dh-sequence-nodejs
...
• debian/tests/pkg-js/test
mocha -R spec
See also pkg-js-autopkgtest README ⟨../autopkgtest/README.md⟩.
Multiple binary packages
When debian/control provides more than one binary package, dh_auto_install
populates a debian/tmp and dh_install install files in each package. In
this case, you must write a debian/<package>.install for each binary
package. Each line with only one argument is related to debian/tmp.
Examples:
• debian/node-arch-indep.install: pick files from debian/tmp
usr/share/nodejs/foo/
• debian/node-arch-dep.install: pick files from debian/tmp
usr/lib/*/nodejs/foo/
• debian/libjs.install: pick files from sources
dist/* usr/share/javascript/foo/
Links
Since path is not fixed for arch-dependent package, you must write
debian/nodejs/links:
# debian/nodejs/links
foo/bin/cli.js /usr/bin/foo
With a arch independent package, pkg-js-tools transforms this into:
/usr/share/nodejs/foo/bin/cli.js /usr/bin/foo
and for a arch dependent package, it uses DEB_GNU_ARCH. Example with amd64:
/usr/lib/x86_64-linux-gnu/foo/bin/cli.js /usr/bin/foo
All fields that does not start with / are prefixed with the good nodejs path
Component docs
Starting from version 0.13.0, pkg-js-tools provides dh_nodejs_autodocs.
This tool automatically install README.md, CONTRIBUTING.md,... for each
root component in its /usr/share/doc/node-<name> directory. And if no
debian/*docs is found, it does the same for the main component. To use it:
override_dh_installdocs:
dh_installdocs
dh_nodejs_autodocs
.eslint* files
pkg-js-tools auto installer always removes .eslint* files unless it
is explicitly specified in debian/nodejs/**/files or
debian/nodejs/**/install.
Having different test between build and autopkgtest
When debian/nodejs/test exists, this file is used during build test instead
of debian/tests/pkg-js/test. This permits one to have a different test. You can
also overwrite dh_auto_test step in debian/rules:
override_dh_auto_test:
# No test during build (test needs Internet)
Autopkgtest additional test packages or test restrictions
autodep8 allows one to add additional packages during autopkgtest (and/or
additional restrictions) by using a debian/tests/autopkgtest-pkg-nodejs.conf
file:
extra_depends=mocha, npm
extra-restrictions=needs-internet
LINTIAN PROFILES
pkg-js-tools provides a lintian profile:
• pkg-js-extra: launches additional checks (repo consistency see .br debcheck-node-repo
below)
To use them:
lintian --profile pkg-js-extra ../node-foo_1.2.3-1.changes
OTHER TOOLS
See related manpages.
• add-node-component: automatically modifies gbp.conf and debian/watch to add
a node component. See
JS Group Sources Tutorial ⟨https://wiki.debian.org/Javascript/GroupSourcesTutorial⟩.
It can also list components or modules (real names)
• getFromNpmCache: export npm cache content to standard output
• github-debian-upstream: launches it in source repo to create a
debian/upstream/metadata (works only if upstream repo is on GitHub)
• nodepath: shows the path of a node module (npm name). You can use -p to
show also the Debian package. Option -o shows only Debian package name.
• debcheck-node-repo: checks repo consistency: compares vcs repo registered
in npm registry with the source repo declared in debian/watch"
• dh_nodejs_autodocs: automatically select and install documentation files
toinstall for each component
• dh_nodejs_build_debug_package: move sourcemap files from binary
packages to a separated debug package
• mjs2cjs: build commonjs file using rollup
• pkgjs-audit: creates a temporary package-lock.json file using Debian
package values used by the module to analyze, and launch a npm audit. If
module is a bundle (and then has a pkgjs-lock\.json), pkgjs-audit uses
pkgjs-lock.json, else it generates its package-lock.json using available
values
• pkgjs-depends: search recursively dependencies of the given module name
(if not given, use current package.json) and displays related Debian packages
and missing dependencies
• pkgjs-install: same as npm install but uses Debian JS modules when
available
• pkgjs-install-minimal: same as pkgjs-install but uses only available
Debian modules. It is included in dh-nodejs so can be used during build
• pkgjs-ls: same as npm ls but it search also in global nodejs paths
• pkgjs-run: same as npm run
• pkgjs-utils, pkgjs-ln, pkgjs-main, pkgjs-pjson: various
utilities. See pkgjs-utils(1) manpage.
