This library allows a tool provider (your app) to receive LTI launches from a tool consumer (i.e. LMS). It validates LTI launches and lets an application interact with services like the Names Roles Provisioning Service (to fetch a roster for an LMS course) and Assignment Grades Service (to update grades for students in a course in the LMS). This library was forked from [IMSGlobal/lti-1-3-php-library](https://github.com/IMSGlobal/lti-1-3-php-library), initially created by @MartinLenord. [Packback](https://packback.co) found the library immensely helpful and extended it over the years. It has been rewritten by Packback to bring it into compliance with the standards set out by the PHP-FIG and the IMS LTI 1.3 Certification process. Packback actively uses and maintains this library. Installation ------------ [](#installation) Run: ``` composer require packbackbooks/lti-1p3-tool ``` In your code, you will now be able to use classes in the `Packback\Lti1p3` namespace to access the library. ### Configure JWT [](#configure-jwt) Add the following when bootstrapping your app. ``` Firebase\JWT\JWT::$leeway = 5; ``` ### Implement Data Storage Interfaces [](#implement-data-storage-interfaces) This library uses three methods for storing and accessing data: cache, cookie, and database. All three must be implemented in order for the library to work. You may create your own custom implementations so long as they adhere to the following interfaces: - `Packback\Lti1p3\Interfaces\ICache` - `Packback\Lti1p3\Interfaces\ICookie` - `Packback\Lti1p3\Interfaces\IDatabase` or optionally `Packback\Lti1p3\Interfaces\IMigrationDatabase` View the [Laravel Implementation Guide](https://github.com/packbackbooks/lti-1-3-php-library/wiki/Laravel-Implementation-Guide) to see examples (or copy/paste the code outright). ### Create a JWKS endpoint [](#create-a-jwks-endpoint) A JWKS (JSON Web Key Set) endpoint can be generated for either an individual registration or from an array of `KID`s and private keys. ``` use Packback\Lti1p3\JwksEndpoint; // From issuer JwksEndpoint::fromIssuer($database, 'http://example.com')->getPublicJwks(); // From registration JwksEndpoint::fromRegistration($registration)->getPublicJwks(); // From array JwksEndpoint::new(['a_unique_KID' => file_get_contents('/path/to/private/key.pem')])->getPublicJwks(); ``` Documentation ------------- [](#documentation) [The wiki](https://github.com/packbackbooks/lti-1-3-php-library/wiki) provides more detailed information about how to use this library, including a [Laravel Implementation Guide](https://github.com/packbackbooks/lti-1-3-php-library/wiki/Laravel-Implementation-Guide). Contributing ------------ [](#contributing) For improvements, suggestions or bug fixes, make a pull request or an issue. Before opening a pull request, add automated tests for your changes, ensure that all tests pass, and any linting errors are fixed. ### Testing [](#testing) Automated tests can be run using the command: ``` composer test ``` Linting can be run using ``` # Display linting errors composer lint # Automatically fix linting errors composer lint-fix ``` ### Health Score 64 — FairBetter than 99% of packages Maintenance84 Actively maintained with recent releases Popularity51 Moderate usage in the ecosystem Community32 Small or concentrated contributor base Maturity77 Established project with proven stability Bus Factor1 Top contributor holds 64.2% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
