Configuring CI Using Jenkins and Nx
Below is an example of a Jenkins setup for an Nx workspace - building and testing only what is affected.
Unlike GitHub Actions and CircleCI, you don't have the metadata to help you track the last successful run on main. In the example below, the base is set to HEAD~1 (for push) or branching point (for pull requests), but a more robust solution would be to tag an SHA in the main job once it succeeds and then use this tag as a base. See the nx-tag-successful-ci-run and nx-set-shas (version 1 implements tagging mechanism) repositories for more information.
We also have to set NX_BRANCH explicitly.
1pipeline {
2 agent none
3 environment {
4 NX_BRANCH = env.BRANCH_NAME.replace('PR-', '')
5 }
6 stages {
7 stage('Pipeline') {
8 parallel {
9 stage('Main') {
10 when {
11 branch 'main'
12 }
13 agent any
14 steps {
15 sh "npm ci"
16 sh "npx nx format:check"
17 sh "npx nx affected --base=HEAD~1 -t lint --parallel=3"
18 sh "npx nx affected --base=HEAD~1 -t test --parallel=3"
19 sh "npx nx affected --base=HEAD~1 -t build --parallel=3"
20 }
21 }
22 stage('PR') {
23 when {
24 not { branch 'main' }
25 }
26 agent any
27 steps {
28 sh "npm ci"
29 sh "npx nx format:check"
30 sh "npx nx affected --base origin/${env.CHANGE_TARGET} -t lint --parallel=3"
31 sh "npx nx affected --base origin/${env.CHANGE_TARGET} -t test --parallel=3 --configuration=ci"
32 sh "npx nx affected --base origin/${env.CHANGE_TARGET} -t build --parallel=3"
33 }
34 }
35 }
36 }
37 }
38}
39The pr and main jobs implement the CI workflow.
