    Core annotations used for value types, used by Jackson data binding package.

    Jackson core is a Java library for processing abstractions (aka Streaming API), implementation for JSON. Jackson core is available via the Maven package manager.

    Jackson core contains core low-level incremental ("streaming") parser and generator abstractions, which is used by Jackson Data Processor. Jackson core also includes the default implementation of handler types (parser, generator) that handle JSON format.

    Jackson core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain word 'json' are JSON-specific.

    Tidelift works directly with the maintainers of Jackson core to offer maintenance, code improvement, license verification, and security updates so you can use psutil for running processes and system utilization in your app.

    You can learn more about Jackson core on the project repo.

    Custom React PropType validators that we use at Airbnb.

    Ajv is the fastest JSON Schema validator for Node.js and browser. Ajv supports draft-04/06/07.

    Ajv generates code using doT templates to turn JSON Schemas into super-fast validation functions that are efficient for v8 optimization. Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks:

    Ajv implements several extensions to JSON Schema specification (e.g., $data reference) and allows users to define their own custom keywords. ajv-keywords defines several useful keywords, some of which will be included in the next versions of JSON Schema specification - propertyNames is included in draft-06 (soon to be published) and if/then/else is considered for draft-07.

    Because we work directly with the maintainer of Ajv, the Tidelift Subscription ensures any Ajv errors are fixed quickly.

    You can learn more about ajv on the Ajv docs and the Ajv repo. You can also check out an interview with Ajv maintainer Evgeny Poberezkin here.

    Browserify lets you require('modules') in the browser by bundling up all of your dependencies. Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Learn more here.

    Browserify is available via the npm package manager.

    Browserslist shares target browsers between different front-end tools, like Autoprefixer, Stylelint and babel-preset-env. All tools will find target browsers automatically, when you add Browserslist to package.json. Browserslist will take queries from tool option, browserslist config, .browserslistrc config, browserslist section in package.json or environment variables.

    Browserslist is sponsored by Evil Martians. You can learn more about Browserslist on the project repo.

    listr is a terminal task list available via the npm package manager. listr maintainer and creator, Sam Verschueren, maintains listr via the Tidelift Subscription. listr is used by more than 165,000 repositories and over 1,000 other projects depend on listr.

    listr does the following:

    • A task can return different values. If a task returns, it means the task was completed successfully. If a task throws an error, the task failed.
    • A task can also be async by returning a Promise. If the promise resolves, the task completed successfully, it it rejects, the task failed.
    • A task can also return an Observable. The thing about observables is that it can emit multiple values and can be used to show the output of the task.
    • It's also possible to return a stream. The stream will be converted to an Observable and handled as such.
    • Optionally specify a skip function to determine whether a task can be skipped.

    Pug is a clean, whitespace-sensitive JavaScript template language for writing HTML. The general rendering process of Pug is simple. pug.compile() will compile the Pug source code into a JavaScript function that takes a data object (called "locals") as an argument. Call that resultant function with your data, and voilà!, it will return a string of HTML rendered with your data. The compiled function can be re-used, and called with different sets of data. Learn more here.

    Pug is available via npm.

    pump is a small node module that pipes streams together and destroys all of them if one of them closes. When using standard source.pipe(dest) source will not be destroyed if dest emits close or an error. You are also not able to provide a callback to tell when then pipe has finished. pump does these two things for you.

    pump is available via the npm package manager.

    pumpify combines an array of streams into a single duplex stream using pump and duplexify. If one of the streams closes/errors all streams in the pipeline will be destroyed.

    pumpify is available via the npm package manager.

    turbo-json-parse is a turbocharged JSON.parse for type stable JSON data. This works by taking the schema of the data and generating a specific JSON parser for exactly that schema.

    Vue.js is a progressive JavaScript framework ranked one of the most popular projects on GitHub in 2017. Integration into projects that use other JavaScript libraries is simplified with Vue because it is designed to be incrementally adoptable.

    Unlike other monolithic frameworks, the Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is easy to pick up and integrate with other libraries or existing projects. Part of what makes it so useable are the Vue component libraries, which can be shared between projects and applications.

    quantmond is a quantitative financial modelling and trade framework for R.

    The quantmod package for R is designed to assist the quantitative trader in the development, testing, and deployment of statistically based trading models.

    quantmod is a rapid prototyping environment, where quant traders can quickly and cleanly explore and build trading models.

    quantmod is not a replacement for anything statistical. It has no 'new' modelling routines or analysis tool to speak of. It offers charting not currently available elsewhere in R, but most everything else is more of a wrapper to what you already know and love about the language and packages you currently use.

    quantmod makes modelling easier by removing the repetitive workflow issues surrounding data management, modelling interfaces, and performance analysis.

    roave/security-advisories is a PHP library that prevents installation of Composer packages with known security vulnerabilities: no API, simply require it. This means that roave/security-advisories keeps known security vulnerabilities out of your project.

    roave/security-advisories means you don't have to install and run an additional CLI tool for something that Composer can provide directly.

    What does that mean?

    roave/security-advisories compiles a list of conflict versions from into a composer metapackage, which has tons of advantages, like:

    • No files or actual dependencies are added to the project
    • Packages with security issues are filtered out during dependency resolution
    • No more CLI tool to run separately, no more CI setup steps
    • No need to upgrade the roave/security-advisories separately
    • No coupling or version constraints with any dependencies used by similar CLI-based alternatives

    roave/security-advisories has been downloaded more than 9 million times.

    You can learn more about roave/security-advisories in this blog post written by the creator.

    roave/security-advisories is available via the Packagist package manager.

    urllib3 is a powerful, sanity-friendly HTTP client for Python. Much of the Python ecosystem uses urllib3. urllib3 brings many critical features that are missing from the Python standard libraries:

    • Thread safety.
    • Connection pooling.
    • Client-side SSL/TLS verification.
    • File uploads with multipart encoding.
    • Helpers for retrying requests and dealing with HTTP redirects.
    • Support for gzip and deflate encoding.
    • Proxy support for HTTP and SOCKS.
    • 100% test coverage.

    urllib3 is used by mainy popular Python packages, like Requests and Pip. Chances are, if you're writing code in Python, you might be using urllib3.

    urllib3 and the maintainers of thousands of other packages are working with Tidelift to deliver one enterprise subscription that covers all of the open source you use. If you want the flexibility of open source and the confidence of commercial-grade software, this is for you.

    Check out this blog post about how Tidelift worked with the maintainers of urllib3 to create a coordinated security vulnerability disclosure to help Tidelift subscribers avoid zero-day fire drills.

    Oj gem (Optimized JSON) is a fast JSON parser and Object marshaller as a Ruby gem. OJ gem is faster than the built in Ruby json gem. Oj gem achieves this by implementing the encoding and decoding of JSON in C, as a C extension to Ruby.

    The approach taken by both the json gem and ActiveSupport is to push JSON encoding to the individual object and then patching those objects to implement encoding and decoding. Oj gem take a different approach and looks at Ruby objects as data and keeps the endcoding in C instead of going out to each object and encoding in Ruby. This is more of a service of function programming approach to encoding. Learn more.

    oj gem is available via the RubyGems package manager.
