Therefore, I would strongly encourage calling crypto interface methods directly in your codebase. Developers reviewing UUID generation code of a codebase will want to be confident and certain that they are accessing crypto's secure random number generation, instead of less secure methods. The native crypto random call is a critical system-level API call to request cryptographically secure random numbers. However, a security conscious developer may not, in general, want the native crypto random call(s) buried deep within package sub-modules, and then, even more, behind walls of conditional logic. A crypto.randomFillSync() call is likely of equivalent robustness to crypto.randomUUID(), so this is likely not a concern. Observe from src/v4.js that passing either a buf or options argument to uuid.v4() will cause it to no longer call crypto.randomUUID() for the random uuid, instead it will use either a passed source of randomness from options, or fallback to a crypto.randomFillSync() call. Minor additional notes for those who wish to split hairs: Which references a native module, which exports crypto.randomUUID as randomUUID: You can observe this by viewing the source code of the uuid npm package: The choice between the two methods depends on the specific requirements of your application. UUIDs are a good choice for generating globally unique identifiers, while Crypto.randomUUID is useful for generating unique identifiers within the context of a single user's browser. In conclusion, both UUIDs and Crypto.randomUUID are useful methods for generating unique identifiers in JavaScript. This can be useful for generating unique identifiers for session tokens or user IDs. Crypto.randomUUID is a good choice when you need to generate unique identifiers within the context of a single user's browser. They are widely used and well-established in the computer industry. UUIDs are a good choice when you need to generate unique identifiers for objects in a distributed system or across multiple systems. Another difference is that UUIDs are designed to be globally unique, while Crypto.randomUUID is unique within the context of the user's browser. UUIDs are generated using a specific algorithm that ensures they are unique, while Crypto.randomUUID uses a cryptographically secure random number generator to create unique identifiers. The main difference between UUIDs and Crypto.randomUUID is the way they generate random numbers. Import * as esbuild from 'esbuild' let result = await esbuild.Enter fullscreen mode Exit fullscreen modeĭifferences between UUIDs and Crypto.randomUUID: Here's a simple example that enables bundling with an output directory:ĬLI JS Go esbuild app.ts -bundle -outdir=dist You typically pass one or more entry point files to process along with various options, and then esbuild writes the results back out to the file system. This is the primary interface to esbuild. ![]() Each is described below at a high level, followed by documentation for each individual API option. The two most commonly-used esbuild APIs are build and transform. There is separate documentation for both of the public Go packages: pkg/api and pkg/cli. Go: If you are using Go, you may find the automatically generated Go documentation for esbuild helpful as a reference. You may also find the TypeScript type definitions for esbuild helpful as a reference. JavaScript: If you are using JavaScript be sure to check out the JS-specific details and browser sections below. ![]() The form -foo is used for enabling boolean flags such as -minify, the form -foo=bar is used for flags that have a single value and are only specified once such as -platform=, and the form -foo:bar is used for flags that have multiple values and can be re-specified multiple times such as -external. Some specifics for each language:ĬLI: If you are using the command-line API, it may be helpful to know that the flags come in one of three forms: -foo, -foo=bar, or -foo:bar. You can switch between languages using the CLI, JS, and Go tabs in the top-right corner of each code example. The concepts and parameters are largely identical between the three languages so they will be presented together here instead of having separate documentation for each language. The API can be accessed in one of three languages: on the command line, in JavaScript, and in Go.
