@labkey/api

API Docs | Change Log | License | Build Status

JavaScript package for interacting with LabKey Server. The goal for this package is to provide a robust set of JavaScript tools for working with LabKey Servers. Our eventual hope is to have it working in the browser, on the server, and in pretty much any modern JavaScript environment. The package currently only supports use in the browser.

Written with joy in TypeScript.

v1.0 - Official stable release

v1.0 is the first stable release of the @labkey/api package. This package is the official JavaScript API package for LabKey Server and is included starting with LabKey Server v20.7. Release highlights:

  • Replaces the original JavaScript API served under LABKEY global namespace on LabKey Server pages.
  • Universal module definition (UMD) published package targeting ES6.
  • Full fidelity TypeScript definitions.

Pre-v1.0 usage

It is highly recommended you update to the 1.x version of this package as soon as possible. Any pre-1.0 releases are considered experimental and were used only for development purposes.

Installation

The easiest way to use @labkey/api is to install it from npm and bundle it with your app. Before you run install you'll want to make sure you set the appropriate registry for the @labkey scope.

Setting the Registry Scope

This package is currently available on LabKey's Artifactory package registry. To include this package set the registry in npm for the @labkey scope. This can be done via command line using npm config:

npm config set @labkey:registry https://labkey.jfrog.io/artifactory/api/npm/libs-client

or via a .npmrc file

# .npmrc
@labkey:registry=https://labkey.jfrog.io/artifactory/api/npm/libs-client

Installing

To install using npm

npm install @labkey/api

You can then import @labkey/api in your application as follows:

import { Query, Security } from '@labkey/api';

Development

If you would like to contribute changes to this package it is straightforward to get set up for development. First, clone this repository to a directory

git clone https://github.com/LabKey/labkey-api-js.git # or via ssh

Navigate into the package directory and run the following commands

npm install
npm run build

Now that the distribution is built you can load it up by serving the index.html file found in the package root. To serve it up from IntelliJ you can "Open in Browser". This will let you explore the API as it is exposed via the LABKEY global namespace.

Local LabKey Server

To make changes to this package and serve those changes from a local LabKey Server instance you can do so via the following steps:

  1. Build the package (as described above).
  2. Copy the package's /dist directory to /<labkey root>/server/modules/platform/core/node_modules/@labkey/api/dist.
  3. Navigate to /<labkey root>/server/modules/platform/core.
  4. Run npm run copy-distributions from the core module directory.

Your changes will now be included in the bundle served by your local LabKey Server instance.

Determining package version

If you're using this package from a LabKey Server page you can verify the package version being used by opening the browser console and typing:

LABKEY.__package__

The __package__ object will contain package information such as the version of the package you're using.

// LABKEY.__package__
{
  description: "JavaScript client API for LabKey Server",
  name: "@labkey/api",
  version: "1.0.0"
}

Publishing

To publish, increment the version number in accordance with SemVer, update the CHANGELOG.md, and commit. Then from the package root run

npm publish
