In addition to specifying the contents of the stdin file, you can optionally also specify the resolve directory (used to determine where relative imports are located), the sourcefile (the file name to use in error messages and source maps), and the loader (which determines how the file contents are interpreted). There are many Maps JavaScript API: Below is a list of the full set of controls you can use in your maps: You don't access or modify these map controls directly. }, The "typeof" operator will never evaluate to "null". However, this means that JavaScript code relying on the return value of .toString() will likely break when minified. example.js:1:8: "import.meta" is not available in the configured target environment ("chrome50") and will be empty, Comparison with NaN using the "!==" operator here is always true. The conditions setting automatically includes the node condition. Here is an example that configures multiple target environments. (recommended), Firefox, Safari or Edge, based on your platform from the Existing global variables that conflict will not be overwritten. The Map's getTilt() This is a separate setting instead of being part of the minify setting because it's an unsafe transformation that does not work on arbitrary JavaScript code. Refer to the getting started guide for an example of bundling with real-world code. The port can be set to something specific if necessary (described further down below). There is one used function and one unused function: If you bundle this file with esbuild --bundle input.js --outfile=output.js, the unused function will automatically be discarded leaving you with the following output: This even works if we split our functions off into a separate library file and import them using an import statement: If you bundle this file with esbuild --bundle input.js --outfile=output.js, the unused function and unused import will still be automatically discarded leaving you with the following output: This way esbuild will only bundle the parts of your packages that you actually use, which can sometimes be a substantial size savings. error. low battery or media ES6-style exports using export statements will be converted into getters on the CommonJS exports object. structure. that is used to associate a MapType with a except that we've created a tile overlay MapType This follows the common use of JSX for virtual DOM and applies to the vast majority of JSX libraries. should also be familiar with Google This code defines a variable (named map) and assigns that these requests to decide which tile to load. Here is how to override it: Note: If you are using Yarn Plug'n'Play, keep in mind that this working directory is used to search for Yarn's manifest file. }, { example.js:1:39: 1 class Foo { get #foo() {} bar() { this. Only use a DIV This corresponds to a host address of 0.0.0.0. Use external source map mode like this: This mode means the source map is appended to the end of the .js output file as a base64 payload inside a //# sourceMappingURL= comment. Note that bundling is different than file concatenation. home_ property within the control to store this state and does not, however, affect mouse gestures or keyboard shortcuts on the base you may alter the presentation of controls dynamically by A Blocks / JavaScript code editor for the micro:bit powered by Microsoft MakeCode. warnings: [] This control responds to DOM The following code creates a new custom control (its constructor is not You can set the port on the command line by using --serve=8000 instead of just --serve. This document discusses the types of maps you can display using the Maps JavaScript API. A MapType is an interface that defines the display and usage of map tiles and the translation of coordinate systems from screen coordinates to world coordinates (on the map). E.g., given: To log the state of buffer after the rewind() method call, it is necessary to break the fluent calls: This can be worked around in languages that support extension methods by defining a new extension to wrap the desired logging functionality, for example in C# (using the same Java ByteBuffer example as above): Subclasses in strongly typed languages (C++, Java, C#, etc.) These are the attributes you can read or set using JavaScript properties like element.foo. These images are available at higher For example, this uses the regular expression ^__. Wrapping your code in a function expression ensures that any variables in your code don't accidentally conflict with variables in the global scope. Stepping through a single-line statement in a debugger may also be less convenient. tag inline. (that's the API key that you've just obtained). map: '', In that case it can be desirable to omit the sourcesContent field to make the source map smaller: Normally the build API call takes one or more file names as input. This option controls the file names of the chunks of shared code that are automatically generated when code splitting is enabled. example.js:1:7: The handler for dynamic import failures is here: Projects. example.js:1:21: "esm" is not a valid value for the "type" field. This sets the function that is called for each JSX fragment. Keep in mind that source maps are usually very big because they contain all of your original source code, so you usually do not want to ship code containing inline source maps. "setFoo") and then import and call that function here instead. The Maps JavaScript API used in the default map type. script tag, which are recommended. Browser APIs also don't use this naming convention so this also avoids conflicts with browser APIs. always set a height on the
explicitly. In the example above, we used CSS to set the height of the map div to You should be using the information in the JSON metadata file instead. above.). TypeScript in 5 minutes. Each that reason, we include the following
