I wanted to add a comment, on all the PRs in a changeset, e.g. when deployed to a specific environment.
Assuming you have a commit range, it’s relatively straightforward to get the list of commits between them:
const res = await octokit.request({
method: 'GET',
url: '/repos/{owner}/{repo}/compare/{basehead}',
owner: 'foo',
repo: 'bar',
basehead: `${process.env.GIT_PREVIOUS_SUCCESSFUL_COMMIT}...${process.env.GIT_COMMIT}`
});
Then, for each commit, you can search for a PR containing it:
const commits = res.data.commits.map(c => c.sha);
const results = await Promise.all(commits.map(q => {
return octokit.request({
method: 'GET',
url: '/search/issues',
owner: 'foo',
repo: 'bar',
q,
})
}));
Assuming you only want one comment per PR, you can use a Set to get a distinct list of numbers:
const prs = new Set();
results.forEach(r => {
if (r.data.items.length) {
prs.add(r.data.items[0].number);
}
});
const prList = Array.from(prs.keys());
And finally add a comment on each PR:
await Promise.all(prList.map(pr => {
return octokit.request({
method: 'POST',
url: '/repos/{owner}/{repo}/issues/{issue_number}/comments',
owner: 'foo',
repo: 'bar',
issue_number: pr,
body: `something something: ${process.env.BUILD_URL}`
});
}));
Or, if you’re feeling really brave, you can do the whole thing in one line of bash!
curl -s -u "$GH_USER:$GH_TOKEN" -H "Accept: application/vnd.github.v3+json" "https://api.github.com/repos/foo/bar/compare/$BASE_COMMIT...$HEAD_COMMIT" \
| jq '.commits[] | .sha' \
| xargs -I '{}' sh -c 'curl -s -u "$GH_USER:$GH_TOKEN" -H "Accept: application/vnd.github.v3+json" "https://api.github.com/search/issues?q={}" \
| jq '\''.items[0] | .number'\''' \
| sort \
| uniq \
| xargs -I '{}' sh -c 'curl -s -u "$GH_USER:$GH_TOKEN" -H "Accept: application/vnd.github.v3+json" "https://api.github.com/repos/foo/bar/issues/{}/comments" -d "{\"body\":\"something something: $BUILD_URL\"}" > /dev/null'
