Config files for esbuild.
esbuild is an incredible tool, that is exclusively using command line parameters as a configuration syntax. Some people prefer configuration files, so I thought it could be a good idea to provide a solution for this. It is also for me a pretext to use Rust while learning it :)
Install it with npm:
console
npm i -g esbuild-config
Or from by downloading it from the latest release.
The esbuild-config command outputs a list of parameters based on a esbuild.config.json file, that can get passed to esbuild directly:
console
esbuild $(esbuild-config)
It detects the presence of esbuild.config.json in the current directory, or the project root (using the presence of a package.json file). Any file can also get provided as a parameter:
console
esbuild $(esbuild-config ./my-conf.json)
esbuild-config doesn’t do any validation on the configuration values: it only converts JSON types into arguments that are compatible with the format esbuild uses for its arguments. This makes it independent from esbuild versions, assuming the format doesn’t change.
The only exception to this is the entry field, which gets converted into a list of file names (when an array is provided) or a single file name (when a string is provided).
This is how JSON types get converted:
json
{
"entry": "./index.js",
"outfile": "./bundle.js",
"external": ["react", "react-dom"],
"loader": { ".js": "jsx", ".png": "base64" },
"minify": true
}
Output:
console
--outfile=./bundle.js --minify --external:react --external:react-dom --loader:.js=jsx --loader:.png=base64 ./index.js
Notice how the entry, ./index.js, has been moved to the end. esbuild-config also takes care of escaping the parameters as needed (e.g. by adding quotes).
```console
cargo run
cargo test
cargo tarpaulin -o Html ```
