Update Deno Dependencies

Run this script to update your dependency urls to their latest published versions. Optionally run --test(s) to ensure that each dependency update is non-breaking.

deno-udd

Note: udd is fundamentally different from something like npm or yarn. Other tools do a "distributed update" i.e. every user updates independently (and potentially to untested versions/configurations of dependencies). With udd precisely one person updates (a maintainer), and they can ensure that the new dependencies pass the test suite before commiting/releasing a new version. With udd every user has a fixed version of the dependencies.

Semantic versioning fragments are purely a convenience for the maintainer, and do not affect users.

Installation

Use deno install command:

deno install -A -f udd https://deno.land/x/udd@0.1.2/main.ts

You may need to include the deno bin directory in your PATH.

Usage

For example, to update url imports inside deps.ts run:

udd deps.ts

To update all the ts files in your directory:

udd *.ts

To ensure that deno test is successful when updating each dependency:

udd deps.ts --test="deno test"

Semantic versioning

If you append a fragment #${token}${version} to your urls you can manage their update behavior:

Token	Name	udd updates to the latest version such that
^	Compatible	major version is the same (if major=0 then same minor version)
~	Approximately	major and minor version are the same
<	Less than	less than the provided version
=	Equal	it's exactly this version

The version argument is optional for ^, ~ and = (the version passed is the version in the url).

Examples

-export { Application } from "https://deno.land/x/oak@v2.4.0/mod.ts#^";
+export { Application } from "https://deno.land/x/oak@v2.10.0/mod.ts#^";  // 3.x.y is not chosen

-export { decode } from "https://deno.land/std@v0.34.0/strings/decode.ts#=";
+export { decode } from "https://deno.land/std@v0.34.0/strings/decode.ts#=";  // no change

-export { Application } from "https://deno.land/x/abc@v0.1.10/mod.ts#<0.2.0";
+export { Application } from "https://deno.land/x/abc@v0.1.11/mod.ts#<0.2.0";  // 0.2.x is not chosen

-export { encode } from "https://deno.land/std@v0.34.0/strings/encode.ts#~";
+export { encode } from "https://deno.land/std@v0.36.0/strings/encode.ts#~";  // update to latest compatible
