This folder contains packages that are intended for use in OpenSearch Dashboards and OpenSearch Dashboards plugins.
tl;dr:
- Don't publish to npm registry
- Always use the
@osd
namespace - Always set
"private": true
inpackage.json
We no longer publish these packages to the npm registry. Now, instead of specifying a version when including these packages, we rely on yarn workspaces, which sets up a symlink to the package.
For example if you want to use the @osd/i18n
package in OpenSearch Dashboards itself, you
can specify the dependency like this:
"@osd/i18n": "1.0.0"
However, if you want to use this from a OpenSearch Dashboards plugin, you need to use a link:
dependency and account for the relative location of the OpenSearch Dashboards repo, so it would
instead be:
"@osd/i18n": "link:../../opensearch-dashboards/packages/osd-i18n"
How all of this works is described in more detail in the
@osd/pm
docs.
Create a new sub-folder. The name of the folder should mirror the name
in the
package's package.json
. E.g. if the name is @osd/i18n
the folder name
should be osd-i18n
.
All new packages should use the @osd
namespace, and should be marked with
"private": true
.
Currently there are two patterns used to test packages, one using Mocha and one using Jest. These patterns emerged out of convention and we'd like to make them more similar to each other in the near future.
Today a package can follow the pattern of having a __tests__
directory in each source code directory of a package which contains the tests for that module. These are usually run by Mocha.
If a package's tests should be run with Mocha, you'll have to opt-in to run them by appending the package's test file pattern(s) to OpenSearch Dashboards's src/dev/mocha/run_mocha_cli.js
file. These will then be run by the unit test runner.
yarn test
oryarn grunt test
runs all unit tests.node scripts/mocha
runs all Mocha tests.
A package can also follow the pattern of having .test.js
files as siblings of the source code files, and these run by Jest.
A package using the .test.js
naming convention will have those tests automatically picked up by Jest and run by the unit test runner, currently mapped to the OpenSearch Dashboards test
script in the root package.json
.
yarn test
oryarn grunt test
runs all unit tests.node scripts/jest
runs all Jest tests in OpenSearch Dashboards.
Each package can also specify its own test
script in the package's package.json
, for cases where you'd prefer to run the tests from the local package directory.
