Dependent Libraries¶
Supported Dependent Libraries
FunctionGraph supports both standard and third-party libraries.
Standard libraries
When using standard libraries, you can import them to your inline code or package and upload them to FunctionGraph.
Supported non-standard libraries
FunctionGraph provides built-in third-party components listed in Table 1 and Table 2. You can import these libraries to your inline code in the same way as you import standard libraries.

Other third-party libraries (FunctionGraph has no built-in non-standard third-party libraries except those listed in the preceding table.)
Package the dependency third-party libraries and upload them to an OBS bucket or on the function details page. These libraries will then be used in your function code.
Importing Dependent Libraries
Importing a dependency for Python:
from com.obs.client.obs_client import ObsClient
Importing a dependency for Node.js:
const ObsClient = require('esdk-obs-nodejs');
For standard libraries and supported non-standard libraries, you can directly use them in your function.
For non-standard third-party libraries that are not provided by FunctionGraph, you can use them by performing the following steps:
Package the dependent libraries into a ZIP file, upload the ZIP file to an OBS bucket, and obtain the OBS link URL.
Log in to the FunctionGraph console, and choose Functions > Dependencies in the navigation pane.
Click Create Dependency.
Set the dependency name and runtime, specify the OBS link URL, and click OK.
Figure 1 Setting the dependency¶
On the function details page, click the Code tab, click Add in the Dependencies area, select the dependency created in 4, and click OK.
Figure 2 Selecting a dependency¶
Warning
Each dependency package cannot contain a file with the same name as a code file. Otherwise, the two files may be incorrectly merged or overwritten. For example, if dependency package depends.zip contains a file named index.py, the handler of a function cannot be set to index.handler. Otherwise, a code file also named index.py will be generated.
