This package is published using:

Installation

$ npm install --save @snyk/code-client

Usage

Creates and initializes an instance

import codeClient from '@snyk/code-client';

// An address of server which will be used in order to send code and analyse it.
const baseURL = 'https://www.snyk.io';

Requests the creation of a new login session

const loginResponse = await codeClient.startSession({
  baseURL,
  // An identificator for the editor using the Snyk APIs
  source: 'atom',
});

if (loginResponse.type === 'error') {
  // Handle error and alert user
}

const { sessionToken, loginURL } = loginResponse.value;

Checks status of the login process

const sessionResponse = await codeClient.checkSession({ baseURL, sessionToken });
if (sessionResponse.type === 'error') {
  // Handle error and alert user
}

const isLoggedIn = sessionResponse.value; // boolean

Complete list of events:

• supportedFilesLoaded: uploading supported file extensions, can be also used for instantiating file watcher
• scanFilesProgress: emits a number of files being found
• createBundleProgress: emits a progress in instantiating packages for analysis
• uploadBundleProgress: emits a progress in uploading files
• analyseProgress: emits a progress in analysis job
• error: emits in case of an error

Run analysis

const results = await codeClient.analyzeFolders({
  connection: { baseURL, sessionToken, source },
  analysisOptions: {
    severity: 1,
  },
  fileOptions: {
    paths: ['/home/user/repo'],
    symlinksEnabled: false,
  },
});

Run analysis only for specific file, the one just changed for example

const results = await codeClient.analyzeFolders({
  connection: { baseURL, sessionToken, source },
  analysisOptions: {
    severity: 1,
    limitToFiles: ['recently-changed-file.js'],
  },
  fileOptions: {
    paths: ['/home/user/repo'],
    symlinksEnabled: false,
  },
});

Run analysis and report results to platform

const results = await codeClient.analyzeFolders({
  connection: { baseURL, sessionToken, source },
  analysisOptions: {
    severity: 1,
  },
  fileOptions: {
    paths: ['/home/user/repo'],
    symlinksEnabled: false,
  },
  reportOptions: {
    enabled: true,
    projectName: 'example-project',
  },
});

Creates a new bundle based on a previously uploaded one

const results = await codeClient.extendAnalysis({
  ...previousAnalysisResults,
  files: {
    '/home/user/repo/main.js',
    '/home/user/repo/app.js',
  },
});

Run analysis on an existing SCM project and report results to platform

const results = await codeClient.analyzeScmProject({
  connection: { baseURL, sessionToken, source },
  analysisOptions: {
    severity: 1,
  },
  reportOptions: {
    projectId: '<Snyk Project UUID>',
    commitId: '<Commit SHA to scan>',
  },
});

Errors

If there are any errors the result of every call will contain the following:

const { error, statusCode, statusText } = result;

CLI

There is a way to run separate calls using a CLI

Create bundle

Help manifest: time npm run cli -- help bundle:create

Usage: CLI bundle:create [options]

create a new bundle and return its ID with meta info

Options:
  --patterns [string...]     supported file patterns
  --ignore [path...]         ignored path glob
  --path [path...]           source code dir
  --url <url>                service URL
  --token <hash>             user token
  --org <string>             organization
  --source <string>          source identifier (default: "code-client")
  -H, --headers [string...]  custom headers e.g. "X-Custom-Header: some value". Can have multiple values diveded by space
  --debug                    enable debug mode
  -h, --help                 display help for command

Example call:

npm run cli -- bundle:create --url="<service url>" --token="<snyk token>" --headers="<extra>" --patterns=".*" --path="<absolute path>"
