Orama Search is an open-source full-text search engine written in TypeScript. The video explains how to set up Orama, create a schema, and perform searches. It emphasizes the benefits of using ECMAScript Modules (ESM) over CommonJS, particularly the use of the 'import' statement and top-level await. The speaker recommends using pnpm for package management due to its efficient caching mechanism, which is especially useful for monorepos. The workshop involves downloading a dataset, creating a schema, and querying the database using Orama's search function. The video also covers how to integrate Orama with a Fastify server for handling search queries via HTTP requests. Additionally, it mentions the BM25 algorithm for scoring search results and the potential for running Orama on CDNs for better performance and scalability.

From Author:

In this workshop, we will see how to adopt Orama, a powerful full-text search engine written entirely in JavaScript, to make search available wherever JavaScript runs. We will learn when, how, and why deploying it on a serverless function could be a great idea, and when it would be better to keep it directly on the browser. Forget APIs, complex configurations, etc: Orama will make it easy to integrate search on projects of any scale.

This workshop has been presented at Node Congress 2023, check out the latest edition of this JavaScript Conference.

FAQ

Orama is a full-text search engine written entirely in TypeScript. Initially named Lyra, it was renamed due to naming conflicts with existing entities. Orama supports the development of applications requiring search functionalities.

Participants need to have Node.js installed, with a version greater than or equal to 16. This is necessary to ensure compatibility and performance during the workshop.

To install Orama, create a new project folder, initialize it with a package manager like pnpm, and then add Orama as a dependency. After setting up, you can begin testing by creating and querying a database within the project.

ECMAScript modules (ESM) are the standard JavaScript modules system supported natively from Node.js version 16 onwards, allowing the use of the 'import' statement. CommonJS modules, on the other hand, use 'require' for importing modules. ESM enables features like top-level await and is considered more modern than CommonJS.

The main advantage of using pnpm is its efficient handling of node modules through a caching mechanism that avoids redundant downloads. This makes development faster and less resource-intensive, especially beneficial in projects with multiple dependencies.

To create a schema in Orama, define an object specifying the types for each field you want to index, such as strings or numbers. This schema helps structure the data for effective indexing and querying in the Orama search engine.

Using updated node versions, like node 20, ensures compatibility with the latest features and optimizations in Orama. It also helps in maintaining security and performance improvements offered by newer versions of node.js.

Yes, as an open-source project, Orama welcomes contributions from developers. Interested individuals can participate by submitting pull requests, reporting bugs, and suggesting enhancements on the project's GitHub repository.

Passwordless authentication may seem complex, but it is simple to add it to any app using the right tool.
We will enhance a full-stack JS application (Node.JS backend + React frontend) to authenticate users with OAuth (social login) and One Time Passwords (email), including:- User authentication - Managing user interactions, returning session / refresh JWTs- Session management and validation - Storing the session for subsequent client requests, validating / refreshing sessions
At the end of the workshop, we will also touch on another approach to code authentication using frontend Descope Flows (drag-and-drop workflows), while keeping only session validation in the backend. With this, we will also show how easy it is to enable biometrics and other passwordless authentication methods.

Making JavaScript on WebAssembly Fast
Top Content
WebAssembly enables optimizing JavaScript performance for different environments by deploying the JavaScript engine as a portable WebAssembly module. By making JavaScript on WebAssembly fast, instances can be created for each request, reducing latency and security risks. Initialization and runtime phases can be improved with tools like Wiser and snapshotting, resulting in faster startup times. Optimizing JavaScript performance in WebAssembly can be achieved through techniques like ahead-of-time compilation and inline caching. WebAssembly usage is growing outside the web, offering benefits like isolation and portability. Build sizes and snapshotting in WebAssembly depend on the application, and more information can be found on the Mozilla Hacks website and Bike Reliance site.

Webpack in 5 Years?
Top Content
In the last 10 years, Webpack has shaped the way we develop web applications by introducing code splitting, co-locating style sheets and assets with JavaScript modules, and enabling bundling for server-side processing. Webpack's flexibility and large plugin system have also contributed to innovation in the ecosystem. The initial configuration for Webpack can be overwhelming, but it is necessary due to the complexity of modern web applications. In larger scale applications, there are performance problems in Webpack due to issues with garbage collection, leveraging multiple CPUs, and architectural limitations. Fixing problems in Webpack has trade-offs, but a rewrite could optimize architecture and fix performance issues.

Towards a Standard Library for JavaScript Runtimes
Top Content
There is a need for a standard library of APIs for JavaScript runtimes, as there are currently multiple ways to perform fundamental tasks like base64 encoding. JavaScript runtimes have historically lacked a standard library, causing friction and difficulty for developers. The idea of a small core has both benefits and drawbacks, with some runtimes abusing it to limit innovation. There is a misalignment between Node and web browsers in terms of functionality and API standards. The proposal is to involve browser developers in conversations about API standardization and to create a common standard library for JavaScript runtimes.
