dnt - Deno to Node Transform
Prototype for a Deno to Node/canonical TypeScript transform.
Note: This is not completely working yet. Please don't use it as it will probably drastically change.
CLI Example
# install
deno install --allow-read --allow-write --allow-net -n dnt https://deno.land/x/dnt/cli.ts
# clone a Deno-first repo
git clone https://github.com/dsherret/code-block-writer.git
cd code-block-writer
# run tool and output to ./code-block-writer/npm/dist (uses tsc CLI flags)
dnt mod.ts --target ES6 --outDir ./npm/dist --declaration
# go to output directory, run tsc, and publish
cd npm
npm publish
JS API Example
To emit the Deno-first sources to code that can be consumed in Node.js, use the
emit
function:
// docs: https://doc.deno.land/https/deno.land/x/dnt/mod.ts
import { emit } from "https://deno.land/x/dnt/mod.ts";
const emitResult = await emit({
compilerOptions: {
outDir: "./dist",
},
entryPoint: "./mod.ts",
shimPackageName: "deno-shim-package-name",
typeCheck: false,
});
For only the Deno to canonical TypeScript transform which can be useful for bundlers, use the following:
// docs: https://doc.deno.land/https/deno.land/x/dnt/transform.ts
import { transform } from "https://deno.land/x/dnt/transform.ts";
const outputFiles = await transform({
entryPoint: "./mod.ts",
shimPackageName: "deno-shim-package-name",
keepExtensions: false, // transforms to not have extensions
});
Rust API Example
When using TypeScript, the Rust API only transforms from Deno to canonical TypeScript. You will need to use the TypeScript compiler to do the rest.
use std::path::PathBuf;
use deno_node_transform::ModuleSpecifier;
use deno_node_transform::transform;
use deno_node_transform::TransformOptions;
let output_files = transform(TransformOptions {
entry_point: ModuleSpecifier::from_file_path(PathBuf::from("./mod.ts")).unwrap(),
keep_extensions: false,
loader: None, // use the default loader
}).await?;
for output_file in output_files {
// use these properties on output_file
output_file.file_path;
output_file.file_text;
}
