atomist sdm goals npm version

Atomist software delivery machine (SDM) extension pack providing fingerprinting support.

See the Atomist documentation for more information on what SDMs are and what they can do for you using the Atomist API for software.

Features

This pack sets a goal to monitor all git pushes and trackes the following aspects:

  • leiningen project.clj files are monitored for updates to library dependencies and project version.
  • maven pom.xml files are monitored for updates to maven library dependencies and version coordinates.
  • npm package.json files are monitored for updates to module dependencies and package version changes.

This monitoring happens computing a set of fingerprints on every commit. The fingerprints that are computed depend on the type of project. We currently compute fingerprints for maven, clojure, and npm projects.

  • npm-project-deps, clojure-project-deps, and maven-project-deps
  • npm-project-coordinates, clojure-project-coordinates, maven-project-coordinates

When a new fingerprint is computed, we can drive interesting behaviors such as:

  • check whether a library is up to date with a set of team-wide goals and offer to push a PR if not
  • check whether a new version of a library is available and check whether consumers need to update to this new version

Usage

Make the following updates to your machine:

  1. Add the imports and create a Goal to represent dependency fingerprinting
import { fingerprintSupport } from "@atomist/sdm-pack-fingerprints";
import { Fingerprint } from "@atomist/sdm";

// create a goal to fingerprint all new Pushes
export FingerprintGoal = new Fingerprint();
  1. Enable the FingerprintGoal for some push rules. Normally, this is done as part of creating your machine:
    // there will usually be more than one Push rule here
    const sdm = createSoftwareDeliveryMachine({
            ...config
        },
        whenPushSatisfies(IsLein)
            .itMeans("fingerprint a clojure project")
            .setGoals(FingerprintGoal));

  1. Add the pack to your new sdm definition:

There'll be some new imports:

import {
    fingerprintSupport,
    forFingerprints,
    renderDiffSnippet,
    depsFingerprints,
    logbackFingerprints,
    renderData,
    applyFingerprint,
    FP,
} from "@atomist/sdm-pack-fingerprints";

and then you'll have to add the extension pack to your machine definition:

    // add this pack to your SDM
    sdm.addExtensionPacks(
        fingerprintSupport(
            FingerprintGoal,
            async (p: GitProject) => {
                // COMPUTE fingerprints: called on every Push
                return depsFingerprints(p.baseDir);
            },
            async (p: GitProject, fp: FP) => {
                // APPLY fingerprint to Project (currently only through user actions in chat)
                return applyFingerprint(p.baseDir, fp);
            },
            {
                selector: forFingerprints("backpack-react-scripts"),
                handler: async (ctx, diff) => {
                    // HANDLE new fingerprint (even if it hasn't changed in this push)
                    return checkFingerprintTargets(ctx, diff);
                },
                diffHandler: async (ctx, diff) => {
                    // HANDLE new fingerprint (only when the fingerprint sha is updated)
                    return renderDiffSnippet(ctx, diff);
                },
            },
        ),
    )

In the example above, we have a module which computes a set of fingerprints on every Push (one of them is named backpack-react-scripts). The pack also notices if a newly computed fingerprint has either changed, or is different from a goal state. It will then present the user with options to do things like:

  • set new targets
  • update a project to be in sync with a target fingerprint
  • apply a fingerprint to a project for the first time
  • broadcast a message to all projects out of sync with the fingerprint

Support

General support questions should be discussed in the #support channel in the Atomist community Slack workspace.

If you find a problem, please create an issue.

Development

You will need to install node to build and test this project.

Build and test
